Most of us are experiencing some form of pandemic-related stress right now. We have all had our routines disrupted, even those of us who are considered “essential workers” and still get to go to work and have social contact there. We have lost our usual day-to-day contacts and activities, and are now restricted in how often we can go out, when we can run errands, etc. Add to that the generalized anxiety many of us share with respect to the future and it’s easy to feel like our lives are out of control.
Welcome to the world of your dog. Or your cat. Or your bird or goldfish, for that matter.
We all have a taste now of what it feels like to have an external force that is beyond our control, determining where we can walk, when we can walk, where we can eat, and what recreational activities are available to us. Our household companions grow up with these restrictions. However, think about how unsettling it must be when their regular daily patterns change. Every time our work schedule changes, or we alter our exercise routines, move to a new house, add another family member or pet, rehome an animal… Some animals are very adaptable and “go with the flow” even when accommodations are not specifically made for them, but many cannot. They feel threatened by the new level of unpredictability that is introduced into their lives with change.
These animals sometimes exhibit destructive, passive, or aggressive behaviors as a result of their stress. We may mistake these behaviors as “acting out” because our pets are “angry” when, in reality, they are trying to soothe or protect themselves. Have you been snappy with your partner, felt like staying in bed all day, not even been able to decide what to eat, or just wanted to PUNCH SOMETHING? If so, you know exactly how stressed pets feel!
All of our pets are”captive species,” a term we used to reserve for wild animals in captivity. Please let your own experience as a “captive species” during the pandemic inform your view of the world your pets inhabit. Their lives will be better for it!
What is pre-anesthetic screening?
“Pre-anesthetic screening” is the term we use to describe tests we use to assess your pet’s fitness for anesthesia. At Integrative Veterinary Care, our standard pre-anesthetic screening is comprised of a small blood chemistry panel to look at basic kidney function and a few other indicators, a complete blood count which allows us to see whether your pet has adequate blood platelets (cells involved in clotting!) and red cells (which carry oxygen), and an ECG (also called an EKG) to assess heart rate and rhythm from the heart’s perspective. In some cases, we need to run an expanded panel, thyroid level, or do chest radiographs (x-rays) to assess heart size and shape.
Why do pre-anesthetic screening?
In the young, overtly healthy pet, we run these tests to look for congenital or developmental anomalies that are invisible on physical examination but which may make anesthesia unnecessarily risky for your pet. One example would be the case of congenital kidney disease that I identified in a 6 month old Maltese who was supposed to be spayed. We had no idea that her kidney values would be 2-3 times normal, because she was running around and eating and drinking like any other puppy. Her owners decided to forego the risk of surgery.
In the older pet, pre-anesthetic screening can unearth issues we had no idea about, but which need to be resolved to minimize anesthetic risk. A fairly common finding is a cardiac arrhythmia called ventricular premature complexes, which can be associated with underlying disease and which, if frequent enough under anesthesia, can be fatal. We have also identified “heart block,” where the electrical impulse is prevented by some anomaly from travelling smoothly from the atria to the ventricles, preventing appropriate changes in heart rate to maintain adequate blood flow to the tissues in the event of a change in blood pressure, etc. In one case, we identified a potentially fatal arrhythmia that was secondary to a urinary tract infection!
The bottom line is that the more information we have about your pet’s physical state, the better job we can do at making anesthesia as uneventful as possible.
My dog or cat (or rabbit, or chicken) spends the day outside…
If your pet spends the day outside, it is possible to keep them safe even in very hot weather, as long as they are healthy. Healthy animals with normal mobility are pretty capable when it comes to keeping themselves as comfortable and safe as possible if provided with appropriate resources. Be aware that pets with short, flat faces (brachycephalic animals) or conditions that affect breathing (such as laryngeal paralysis) may be at risk of overheating when the temperature rises above 80 degrees Fahrenheit, even with appropriate shade, water, etc…
Shade is crucial. If your pet is outside in hot weather, make sure that there is an area available for shelter from heat that is open to moving air and provides an area of all day, full shade at least twice as large his or her bed. This shaded area must be protected by a wall, fence, double layer of shade cloth, or reflective space blanket on the south side to prevent sun exposure from the “hot” side. There must also be an overhang, which can be a roof, double layer of shade cloth, space blanket, pop-up shade structure, or mature tree. Water needs to be available in this fully shaded area, ideally positioned near the center of the “wall” or in a corner to prevent exposure of the water dish to sun and excessive heat.
Rabbits with outdoor run areas may appreciate an artificial burrow, which could be created using retaining wall bricks for walls and a wide board to create a roof, which can be covered with dirt. The entrance should be north-facing, and shading the area is ideal.
Provide at least twice as much water as you think your pet might need, which means at least 2.5 quarts (10 cups) of water per 25 lbs of dog, and 2 cups of water per 8 lbs of cat or rabbit. Remember that larger amounts of water will warm up less quickly, and excess provides “room for error” in case your pet steps in the dish or an unexpected visitor (raccoon, cat) comes to tank up!
Automatic watering systems are a great idea, with some caveats. It is essential that the entire unit be shaded from the faucet (or tank, if the system is gravity-fed) to the dish or sipper. It is essential to test all outlets on such systems daily to make sure that water flow starts and stops like it is supposed to, and to check both the line and outlets for leaks. Check the outlets daily for debris or build-up that could affect the function of the unit or palatability of the water. Make sure that outlets are cleaned thoroughly at least once weekly. It is prudent to have a second bottle available to small mammals who rely on LIXIT-style bottles for water, in case one unit drips and goes dry.
Rabbits and chickens may not drink enough when it is hot, leading to dehydration and intestinal distress. Electrolyte preparations are available for both species. When electrolytes are used, only water with electrolytes should be available. Adding probiotics to the animal’s regimen may also help prevent intestinal distress. Probiotics administered in water are available for rabbits and for chickens.
If your dog is prone to stop drinking with stress, offering diluted bone, chicken, or beef broth twice daily may be helpful. Alternatively, mixing a small amount of meat baby food or other pureed meat into water may promote water consumption. Never leave broth or water with meat mixed into it out for more than an hour before discarding the remainder, or bacterial growth may cause intestinal problems. Flavored water may also be attractive to insects, especially flies.
Cats may be encouraged to drink more by offering water in a recirculating fountain, or simply by placing water in more locations, especially near favored resting spots.
Mister systems can be a great way to keep an area cooler. I do recommend putting them on a timer to prevent the formation of a mud pit or wading pond. It is acceptable to have the mister spray part of the shaded area, but the entire area should not be treated in case your pet needs a dry space to rest in. For rabbits housed in hutches, or chickens, misters can be mounted on the roof of the hutch or coop, on top/outside of the animal’s living space, to keep the roof, and thus the living area, cooler. Never put misters directly on the animals or where their food or bedding will get wet to minimize the risk of mold growth, fly/maggot exposure, etc.
Some animals like their water cool. Putting ice cubes or frozen, hard-sided cooler packs in the water dish helps keep it cool. If you do this, do provide 2 water containers, one with and one without the ice, just in case your pet needs the water to be closer to the ambient temperature in order to drink.
Dogs and chickens get tremendous enjoyment from ice blocks with frozen food treats inside. Both species like chunks of meat, fruits, and vegetables in their ice blocks. There are containers complete with platters that you can use to make ice blocks, or you can use your own plate or pan for serving.
Rabbits may benefit from placing a frozen bottle full of water in their “indoor” area to use as an air conditioner. Some rabbits will snuggle up to the bottle directly to cool down.
Any time you use ice, whether it is contained in plastic or open to the air, it is essential to keep the area around the ice clean. Bedding or food that gets wet, whether due to melting ice or condensation forming on containers, needs to be removed and replaced each evening. When the weather is warm enough that we are worried about keeping our pets cool, mold and bacteria can begin to grow within hours, and wet or musty bedding and decaying food are highly attractive to insects and rodents.
Garages as Shelters
If your pet lives in the garage or has shelter there during the day, a few precautions are necessary. It is never a good idea to leave the front garage door partially open for ventilation – a strategy commonly employed by dog owners. One problem with this technique is that while you may be able to leave a crack that your dog cannot get out through, other animals on the street may be able to get in. Even if other animals don’t get in, your dog will likely experience barrier frustration as he watches other dogs, cats, people and cars pass by, which leads to nuisance barking and aggressive behavior. Newer, non-wood garage doors are also slightly flexible, and I have seen a large dog force his way through an aluminum door by exerting pressure under the center of the door, bending it several inches to escape and charge another dog.
A better strategy is to prop open the door into the yard, which can be protected with a screen if necessary. A pet access flap can be installed in the wall near the walk-through door, if needed. Windows can be opened for further ventilation. A fan placed in a window or hung in the doorway will provide air flow. A swamp cooler or small portable air conditioner can be used to maintain a more constant temperature. Cooling pet beds can also be placed in the garage – they tend to be UV light sensitive, so outdoor use is not generally recommended. There are, however, a number of new cooling beds made of novel materials which are designed specifically for indoor/outdoor use. (Look at “cooling beds” on the In The Company Of Dogs website.)
Dogs of all sizes and shapes who enjoy splashing in water will like having a wading pool. I prefer the more expensive kiddie pools with textured bottoms. (I have had the same $35 kiddie pool for almost 20 years!) If you provide a wading pool for your dog, be sure that it is placed in an area where splashed water will drain and mud will not be a problem. The pool should be drained every 3 days to prevent mosquitoes from breeding in the water. The wading pool should NOT be the only source of water available to your pet – make sure that plenty of water is available in an appropriate container, as outlined above.
A few web searches will turn up dozens of ideas for using solar fans, shade material, and even household items to help keep your animals cool. Do keep in mind the safety and sanitation needs of your specific pet. Beds which are appropriate for a well-behaved, mobile dog may be inappropriate for a crazy chewer or a dog with urinary incontinence who might get stuck trying to get up. Solar fans, appropriately placed for ventilation, might help cool your birds, but beware of the avian tendency to pick at cables and the possibility of kicking up dust with the breeze. If you have an idea and you are just not sure about safety, call your veterinarian’s office and ask – or email a sketch or photo of what you are planning!
I know it happens and I understand.
Your cat gets into a fight, your dog comes up limping, your rabbit starts sneezing, your chicken just doesn’t look quite right… so you wait “a few days to see if it gets better.” Sometimes that’s OK, sometimes it’s not. The problem is that I cannot necessarily give you any good guidelines for telling the difference. Sometimes it’s not even possible to tell you whether or not it’s OK to wait when you call us. And while waiting may save you an exam fee and “a wasted trip,” sometimes waiting costs more money and has an adverse effect on your pet’s outcome.
One example is Midnight, the limping cat who got into a fight with a neighborhood bully almost a week before coming in. The swelling in his leg, which started the next day, improved with time, but Midnight was still unable to use the leg. The family was unable to appreciate that the swelling happened to be directly over a complex joint, and that the joint had been penetrated. By the time Midnight came in, the abscess had ruptured and was dripping joint fluid and pus. A situation that could have been treated within the context of an office appointment with 2-3 weeks of antibiotics, and a follow-up appointment, if he had been seen the day after the fight, required lavage and repair of the joint capsule, placement of a drain under the skin and a flesh wound repair, and 2 follow-up appointments with 6 weeks of antibiotics.
Another example is Harry the sneezing rabbit. Harry had been sneezing for about a month, and his appetite and activity seemed to be normal, but the sneezing was becoming more vigorous and more frequent. Since the change had been so gradual, his family failed to observe Harry’s progressive weight loss and the change in his stool from normal pellets to dehydrated little rocks. When Harry came in, he was underweight, had a runny nose, and he was developing pneumonia. After a week of antibiotics, his family realized how sick he had been when they saw his activity, appetite, and stool return to normal.
If you see your pet do something, like jump off the couch or get into a fight, and they seem painful or even just “off” and aren’t basically normal the next day, bring them in for an exam. If your dog misses a meal or vomits once but seems OK otherwise, go ahead and watch for a day or two, but make a note on your calendar to help you keep track of when it happened. If your cat misses a meal or vomits, call your veterinarian to see whether you should watch him or bring him in. Cats should not skip meals, and vomiting more than a few times a year can be an indicator of underlying problems. If your rabbit, guinea pig, rodent, or chicken (unless she’s molting) misses a meal, call. These guys should never stop eating – if they do, there is a problem.
Anything else that your animal companion does that is abnormal, put on your radar. If you notice your pet doing it a third time, call your veterinarian. An incident that may not be a huge warning signal for some animals may be a problem for your own pet, depending on his previous history. And you, as the caregiver, know better than anyone what that history is.
You may not think so, but that flabby tabby sleeping on the couch probably has stress.
Consider how cats were designed to live, inhabiting an acre or more, primarily solo, occasionally interacting with another cat with an intersecting territory, eating mice and/or birds. (It takes a lot of mice to feed a cat – all of that hunting takes a lot of time.) Maintaining their territory and protecting their resources is essential to survival. They are naturally vigilant and neophobic (afraid of new things), and give suspicious objects and individuals a wide berth. If there is too much stress in a neighborhood, they move.
Now consider how indoor cats live with us. They are usually confined to an area of less than 2000 square feet, in close proximity to other individuals without the opportunity to select their roommates, sharing potty areas, sleeping spots, food, and water. Their environment may change at random (new furniture, new odors, favorite items stolen, strange people knocking down walls and altering countertops, etc) and they have no control over the access of other animals to the borders of their territory (windows, doors). The list of stressors can be endless.
Combine the elevated stress hormones with an endless supply of high-carbohydrate dry food (spaghetti with meatballs) and an almost empty calendar of events, and it’s no wonder most tabbies are flabby!
While this lifestyle does protect our feline friends from being hit by car, bitten by dogs, getting lost, and a host of other bad things, the obese and sedentary lifestyle comes with a host of negatives of its own. There is an intricate interplay between stress hormones, obesity, and inflammation that can influence pancreatic health and diabetes, arthritis, inflammatory bowel disease, interstitial cystitis (formerly known as Feline Urologic Syndrome), and probably every other inflammation-prone tissue in the body. There are also behavioral consequences of this lifestyle, including urine marking, inappropriate elimination, inter-cat aggression, and aggression redirected toward humans, other animals, or the environment.
So what can you do?
The most important thing to remember is that cats have less stress when there are more resources. Not more in bulk, but more in terms of access points. A larger number of resource clusters allows cats to exist in a smaller territory.
Food: Choose a high-protein dry (unless your cat’s medical status dictates otherwise) to supplement a canned base diet. Canned foods should be without added carbohydrates. An extensive review article published recently in JAVMA indicated that the protein content of the food drives water consumption and influences a number of other factors which are beneficial to urinary tract health, gastrointestinal health, and weight management. Dry food should ideally be distributed in small quantities around the house, either in bowls or in food-dispensing toys. Food can be elevated on a perch, on the floor, under the bed, in a closet… Or hidden under a box. The cheapest food-dispensing toy ever is simply a toilet paper tube with one end closed. Spreading out food like this decreases stress in multicat households and allows the cat to engage in some purposeful hunting behavior, mimicking a cat’s wild feeding pattern.
Litter boxes: Even a cat living solo may need more than one toilet, especially if the cat is arthritic or the house is especially large. Split level homes should have a litter box on each level – think one litter box per shared people restroom if you only have one cat. Multi-cat households need even more – a good guideline is one more litter box than you have cats, but here it gets tricky. Two litter boxes side by side, with no divider, is really one restroom with 2 toilets and no privacy. Kitty stress will be reduced and litter box access will be improved if the litter boxes are at least separated, and are arranged in a manner which prevents one cat from guarding access to them all at the same time.
Scratching posts and perches: People have people furniture in every room of the house. The cats should have some furniture, too – at least in shared areas. Scratching posts should be somewhat spread out, ideally with one per cat because the posts really are territorial markers. I personally find the combination kitty towers to be attractive to the cats, attractive to the people, and effective. Perches do not have to be limited to kitty towers and the tops of posts, however. Beds on the corner of a desk, on an accessible shelf, or in a window work well. The more cats you have, the greater the need for multiple elevated perches. Elevation provides the cat with a sense of safety and security, and in a multi-cat household reduces the likelihood of agonistic encounters.
Petting and play: To a great extent, your level of interaction with your cat will be dictated by the cat. However, your cat needs some interaction every day. Cats who “don’t like to be petted” may have legitimate pain issues which should be addressed. That being said, most cats are up for a good head rub now and then. Cats can be taught to accept grooming, if you are careful, use a matt rake, and keep sessions short. “Play” for cats can vary greatly, from actively running and jumping after a wand toy to simply watching an object move. If you keep play sessions short, and offer them often, even pretty lethargic cats can be induced to at least throw out a few swats now and then. Wand toys and laser pointers are the most popular toys among cats.
Outdoor access: For some cats, a little taste of the outdoors can make a big difference. There are a number of “window seats” designed for cats that can be installed even in rental units to allow your feline companion his or her own bay window. There are also outdoor units designed like hamster habitats that allow you to create a series of “kitty tubes” outdoor. Some companies make kitty kennels that can be placed outside a window fitted with a cat flap to allow outdoor access. There is often a concern about other cats having access to your cat through the mesh of these enclosures. The kitty kennels can be protected by strategic placement of a few Sssscat units. Motion-activated sprinklers can be used to protect larger areas, like the perimeter of a yard. In reality, as long as direct cat-to-cat contact, with bite wounds occurring, and access to areas used for potties by outside cats is restricted, the risk to your housecat in having this kind of restricted outdoor access is minimal.
In most cases, a few simple adjustments to the environment can make a huge difference in kitty stress.

Leptospirosis is a bacterial disease that usually causes kidney failure but may also cause meningitis or liver failure. Symptoms may include fever, weakness, pain, inappetence, vomiting, and diarrhea. The organisms are shed in the urine of affected animals, including wildlife, and may survive for weeks or even months in water or moist soil. Leptospirosis is commonly considered to be a “wet weather” disease, and direct exposure to carrier animals is not required for infection due to the possibility of the organism being carried in runoff.
To acquire immunity, the immune system must be exposed to characteristic structures, usually proteins, that serve as a fingerprint for a bacterial or viral organism. These structures are found on the outside of the organism. There are three ways for an immune system to see these structures:
Through natural exposure to the organism (infection)
Through intentional exposure to key parts of the dead organism (killed vaccine)
Through intentional exposure to the living organism after the organism has been rendered harmless (modified live vaccine)
While infection typically results in the longest-term immunity to an organism, the disease caused by infection is what we are trying to avoid by inducing immunity. Killed vaccines are much safer than natural infection, however, since the organism is dead and not reproducing in the animal or doing anything else to excite the immune system, an adjuvant (irritant) is required to provoke the immune response. While the organism portion of the vaccine will be removed in the course of developing immunity, the adjuvant usually remains behind and may act to chronically provoke the immune system. Modified live vaccines introduce actual organisms which are unable to cause disease but otherwise behave exactly like an infection, provoking the immune system without the need for adjuvants. These vaccines are completely cleared from the body when their job is done.
Most of our vaccines are against viruses, which are much smaller and have less complex fingerprints than bacteria. Vaccines against bacterial diseases are difficult to develop, very complex, and result in short-term immunity. The original Leptospirosis vaccines were made by essentially running the actual organism through a blender to rupture and kill it. This produced a vaccine that was safe from the perspective of not being able to cause disease, but which had a tremendous capacity to over-excite the immune system because the vaccine not only exposed the individual to the important structures on the outside of the bacteria, but also to all of the stuff on the inside. This gave Leptospirosis vaccines their reputation for causing “bad reactions.” These vaccines typically last approximately 11 months.
What we use:
A huge improvement in the safety and efficacy of Leptospirosis vaccines came with the advent of genetic engineering, which allowed the production of purified subunit vaccines. Through the magic of gene splicing, E. coli was used to produce specific proteins which occur on the outside of the bacteria, reducing the number of molecules in the vaccine, making it safer and more effective. This vaccine still requires the use of an adjuvant and provides approximately 11 months of protection.
A newer vaccine, which now provides immunity against the four major species of Leptospirosis, is a non-adjuvanted modified live vaccine. A virus has been engineered to infect the patient’s cells with harmless components which make the cells pump out proteins and train the immune system to recognize the fingerprint of Leptospirosis. This vaccine mimics natural infection without causing disease, provoking immunity which has been shown to last at least 15 months without the use of an adjuvant and this is the vaccine we are currently using – Recombitek by Merial.

Fast Facts – as related to the UC-Davis School of Veterinary Medicine Class of 1998 in our required Behavior class:
In the early days of veterinary vaccine development, vaccines were by necessity clumsy and nearly impotent concoctions created by treating the disease agent to render it harmless and adding a compound to irritate the immune system and make it notice an otherwise harmless agent. These vaccines were far safer than natural exposure to the disease but contained a lot of extra material that the immune system really didn’t need to worry about, and resulted in relatively short-term immunity (1 year or less). The availability of veterinary care and the expense of vaccination meant that many animals were un-vaccinated or under-vaccinated, and even well-vaccinated animals might have faulty immunity, so Parvovirus, Distemper, and the like were potentially life-threatening risks for young dogs who had not completed their vaccine series.
Enter the modern-day vaccine. The majority of the vaccines administered by veterinary professionals are now genetically engineered, modified-live vaccines that safely mimic an infection – from the immune system’s perspective – and provoke a strong, targeted immune response with the initial injection. Additional doses are administered to make the immune system “remember” the vaccine and put the important information about the diseases into its long-term memory. Even young puppies can now have good protection, and nowadays behavior is a bigger risk to survival than the diseases against which we vaccinate.
Early socialization and training is behavior vaccination!
When should puppies go to their first puppy class and puppy socials? Two to 14 days after coming home! In a perfect world, every puppy would be enrolled in a class taught using positive motivation, reinforcement and reward before coming home. If the start date falls within the first 48 hours of bringing your puppy home, or if your puppy requires a “quarantine” period because he or she just came out of the shelter, leave your puppy at home and attend class solo so you can start your homework and keep from falling behind!
Which puppies can go about the neighborhood on pavement, rock, and bare dirt from the day they come home? Puppies whose mothers are known to have been up to date on their vaccines or vaccine titers, according to their veterinarian, at the time they were bred and who received a vaccine against Distemper, Adenovirus, and Parvovirus from a veterinary professional at least 10 days before they went to their new homes. These puppies should be experiencing the world from the time they come home even if they are only 8 weeks old.
Which puppies should be socialized primarily in their new homes for the first 2 weeks after coming home? Puppies whose breeders use vaccines from the feed store for the mothers and/or the puppies, whose mothers have uncertain vaccine histories, who were not vaccinated before leaving the litter, or who have been out of an animal shelter for less than 2 weeks.
Which puppies should wait longer than 2 weeks after going home to go out and about in their new world? Only puppies who are sick!
