H3N2 Canine Influenza Alert

To Our Valued Clients:

Recently there has been a marked increase in the number of cases of canine H3N2 flu diagnosed in Florida. Canine flu is a HIGHLY contagious virus that spreads rapidly and can lead to serious complications if your dog is unvaccinated or not current on vaccines. Dogs most at risk are those that visit:- doggie daycare, dog parks, training classes, boarding facilities, dog friendly events, dog shows or sporting events or greet other dogs during walks.

Signs of CIV (Canine Influenza Virus) are:

        • Coughing

            • Discharge from eyes or nose

                • Loss of appetite

                    • Lethargy

                  If your dog was vaccinated in 2017 and has received BOTH the initial vaccine and the booster, they are protected. Any ADULT dog who received the initial vaccine in 2017 but not the booster, should come in and get the 2nd vaccine. Any dog vaccinated prior to 2017, needs to be updated.

                  We will not be charging an Office Visit charge for a Flu vaccine ONLY visit. Summer is almost upon us and we want to help keep your pet safe and give you peace of mind to continue your travel plans and outdoor activities.

                  If you’d like more information about canine influenza, please call our office.

                  One of my favorite things about spring and summer is good weather to be outside walking and hiking with my dog Titan. Not that we don’t hike year round, but it’s easy to get out when it’s sunny and warm. But, there is definitely one part of being outside that I do not enjoy that spring brings along with it every year…..TICKS!!!

                  Recently Titan and I were outside just walking around the neighborhood; not even in the woods or high weeds. We came home and started our daily “tick check” after being outside and unbelievably found 6 ticks between the two of us! What was even more shocking was that Titan had 3 different species of ticks on him.

                  As a veterinarian, I commonly discuss ticks and tick borne illnesses in the exam room. But, I am writing this to just keep the threat of tick borne illnesses in the forefront of our minds because it can be truly devastating for not only our pets but for us as well.
                  The three tick species that Titan picked up in my Manassas neighborhood were the Lone Star tick; the Black Legged tick and the American Dog tick. I only had one tick on me and it was a Lone Star tick.

                  Virginia has three species of ticks and we encountered and brought home all 3 of them in one 45 minute walk around my neighborhood! My dog Titan is on monthly preventative ticks products and has a current Lyme vaccine but I had not taken any precautions for me on my short neighborhood walk.

                  Today, I am writing to give an overview of the three tick species that hitchhiked home with Titan and I. If you do not know how to identify the three tick species that are common in our area please check out the website from the Virginia Department of Health:

                  First, I will start with the Black Legged tick because it causes more disease in humans and dogs in the United States than any other tick. The Black-legged tick (also known more commonly as the deer tick) can carry a bacteria called Borrelia burgdorferi. This is the only tick in the Eastern United States that can carry the Lyme bacteria. The nymph and adult ticks can transmit this disease to dogs and humans and need to feed for about 36 hours to transmit the disease. Most dogs who are infected with Lyme disease do not develop clinical signs but are infected subclinically without outward signs of the disease. Those dogs who do develop clinical signs will likely have lameness; lethargy and sometimes a fever and sometimes these signs can occur long after the tick bite. Less commonly, some dogs will develop life threatening kidney disease. The Black Legged tick can also transmit the bacteria Anaplasma phagocytophilum causing many clinical signs and a parasite called Babesiosis that infects red blood cells; both in humans and dogs.

                  The second tick I removed from both Titan and myself and is quickly becoming a problem around the United States for dogs and humans. This is the Lone Star tick. The Lone Star tick should strike fear into any human but especially any red meat loving human-because it can cause a severe red meat allergy in some people (and this Iowa born and raised girl buys her beef by the cow). That being said let’s look at the most common diseases carried by these originally Southwestern United States ticks (they now are one of Virginia’s most common ticks). The Lone Star tick can transmit several bacterial species of Ehrlichia causing Ehrlichiosis in humans and dogs. Tick transmission of Ehrlichiosis takes about 24 hours of feeding for the tick. Ehrlichiosis can cause a variety of symptoms in humans and dogs ranging from very mild fever and lethargy to even death in severe cases. The Lone Star tick can transmit other diseases such as Tularemia and Babesiosis but neither of these are common in Virginia.

                  The third tick I removed from just Titan was the American Dog Tick. This tick can cause Rocky Mounted Spotted Fever (RMSF) in dogs and humans. RMSF is caused by an infection with the bacteria Rickettsia rickettsii. The initial symptoms can be very general just like Ehrlichiosis or Anaplasmosis, but if left untreated up to 25% of these cases can be fatal. It is thought that the American dog tick only needs to feed about 10-20 hours to transmit the bacteria; but studies are showing that very few of the American Dog Ticks carry the bacteria that causes RMSF. That being said, tick prevention is vital because this disease can be deadly to us and our beloved dogs.

                  CaptureSo who needs tick prevention???? All of us. Any dog who goes outside needs tick prevention and possibly lyme vaccination. There currently is not a lyme vaccine for humans, but as soon as a safe vaccine is developed I plan on getting it. Our dogs should be tested at least annually to evaluate their tick exposure and potentially to treat them if they are infected. Currently I am treating Titan with a monthly flea/tick preventative called NexGard which is a chewable treat that he loves. But, there are a lot of other options out there from topicals to a new collar called Seresto that are very safe. For us humans, I think wearing proper clothing, checking for ticks and using products containing DEET if you are hiking. You can do your tick check and shower off that DEET once you get home.

                  A couple of last notes. I didn’t talk about cats today but here is a small bit of information about them. Outdoor cats in Virginia can be affected by tick diseases; usually Cytauxzoon felis; causing a disease known as Bobcat fever. The American Dog Tick and Lone Star Tick can carry this parasite. Unfortunately, this disease kills 25-40% of infected cats. This is a devastating disease that I have yet to diagnose but will likely see in the near future.

                  If you are not using regular tick preventatives in your dogs or indoor/outdoor kitties (remember even song birds and squirrels can harbor ticks-they are truly everywhere) then talk to one of our veterinary team. We have great, safe preventatives and we will be very happy to work with your family to determine which would be best for your furry baby.

                  Did you know that obesity is not just an epidemic in humans but also in pets? According to the Association for Pet Obesity Prevention (APOP), over 57% of dogs and 52% of cats are obese and these numbers are on the rise. Much like humans, obesity in pets can lead to diabetes, heart disease, osteoarthritis, joint problems, and ultimately a shortened life expectancy.

                  Based on a survey created by APOP, a surprising 93% of dog owners and 88% of cat owners thought their pet was in the normal weight range. This disparity is known as the “fat gap” and is thought to be one of the primary factors in the growing rate of pet obesity. To tell if your pet is a healthy weight, use this scoring system. Your pet should rank at about a 3 if he or she is a healthy weight.

                  To keep your pet at a healthy weight, take care in providing him or her with a healthy diet and ensuring the proper amount of exercise. Pet foods have become more calorically dense and people are feeding their pets more. If your pet is already overweight or obese, talk to your veterinarian about the best course of action. Your vet will probably recommend a controlled diet and specific type of food.

                  It can be hard to know what the proper caloric intake and weight should be for your pet so APOP has provided a few useful tables to help. This information does not replace the advice of your veterinarian and should only be used as a starting point.
