Click here for information about the Avian Flu


Avian Influenza, also called H5N1, is a viral disease found in wild and domestic birds. It is transmissible to many mammals, with our biggest concern being pet cats. The most likely ways for cats to become ill is by catching wild birds or from eating a raw-food diet. People can also become sick from avian influenza, though at this time there have been no reported cases of a person becoming infected from a pet cat.

There have been several recent cases of cats contracting avian influenza (and dying) from being fed a commercial frozen raw-food diet. Transmission is also possible from feeding raw (non-pasteurized) milk. Freeze-dried or high-pressure pasteurized diets have a lower risk of causing avian influenza but still have a potential to transmit pathogens. If you are currently feeding a raw diet, we recommend transitioning your pet to a cooked diet. Frozen raw diets can be baked before feeding to kill the virus. 

Cats can also become infected with avian influenza from hunting wild birds. We recommend keeping cats inside at all times, or allowing them outside only while monitored on leash or contained in a catio or cat tent.

Symptoms of avian influenza in cats include respiratory signs such as nasal discharge, coughing and wheezing, and neurologic signs such as wobbliness, difficulty walking and seizures. If you are concerned your cat could be exhibiting signs of avian influenza either call us or your local emergency clinic. Keep in mind that avian influenza is relatively rare, and there are many other diseases that can cause similar signs. If your cat is not allowed outside and is not eating a raw diet then your cat does not likely have avian influenza. If your cat is having trouble breathing or is not able to stand, head to the nearest emergency clinic right away, calling them while en route. 

There is no vaccine to prevent avian influenza in cats.

Home Dental Care for Your Dog

Periodontal Disease
Periodontal disease is one of the most common health issues in veterinary medicine. Even if your dog’s teeth look pearly white and clean, studies show that 80-90% of dogs over the age of 3 have some form of periodontal disease. Whether large or small, adult dogs generally have 42 teeth. In some dogs, especially small dogs, or dogs with shortened muzzles (i.e.; pugs, bulldogs, etc.), we can also see crowding of the teeth, which can trap bacteria and quickly lead to periodontal disease. Pet parents can help reduce the build-up of bacteria and tartar on their pet’s teeth with professional cleanings and routine oral care.

Brushing Your Dog’s Teeth

Brushing is the single most effective means to maintain dental health between professional cleanings. To be effective, brushing needs to be performed several times each week. Of course, daily brushing is best. A gradual approach is needed to get a dog to accept brushing. You will need pet-safe toothpaste and a finger brush or small child’s toothbrush. Dogs can first get used to having someone touch their mouths and teeth and may like to lick the toothpaste. This can be gradually increased to brushing just a couple of teeth at a time. Most dogs will eventually tolerate brushing all the teeth. Only the outsides of the teeth need to be brushed. Dogs should be rewarded with treats or praise during and after brushing.

Chew Toys and Dental Treats

Many chew products are designed to be used regularly to keep tartar from forming on the teeth. For chews the “rule of thumb” is if a fingernail cannot indent the surface of the item, then it should not be given to dogs for chewing. Products such as nylon bones, hooves, antlers, and marrow bones routinely cause tooth fractures and should be avoided. Hard rubber toys such as Kong toys and large rubber balls can be good for chewing. Some softer rawhides can be okay, as well as compressed rawhides. Of course, pet parents should be cautious of their dogs chewing off and swallowing large pieces, as this can lead to problems in the gut. Always monitor your dog while playing with chews and toys and throw away toys and treats that have been shredded or torn into pieces that can easily be swallowed.

Other Home Dental Treatments

Chlorhexidine and Biotrate are effective anti-plaque ingredients. they comes in rinses, gels, toothpastes and water additives. Rinses are applied by squirting a small amount inside the cheek pocket on each side of the mouth. Gels are applied onto the outer surfaces of the teeth. Toothpastes are used in conjunction with brushing and water additives can be used in their regular water bowls or fountains. Some dogs object to the taste of these products, while others accept it with no difficulty. Several dental-specific diets have also been shown to be of benefit in reducing the accumulation of plaque and tartar in dogs either by the design of the kibble or an anti-tartar polyphosphate ingredient.

Oravet barrier sealant is a waxy material that can be applied to the teeth at the time of a dental cleaning to prevent plaque and tartar formation. It is followed by at-home applications on a weekly basis to continue the protection.

The Veterinary Oral Health Council recognizes products that meet pre-set standards of plaque and tartar control. A list of items can be found at VOHC.org.
