It's that time of the year!
Every year in the US, approximately 300,000 dogs and cats are bitten by venomous snakes. These bites can cause serious illness, irrevocable damage, and death. Rattlesnakes live in a wide variety of habitats including but not limited to: deserts, wetlands, and forests from sea level to mountain elevations. Most of the time rattlesnakes are active in the warmer seasons between the spring and autumn. Dogs are more at risk if they accompany their owners on hikes, camping or hunting. Just like us they can stumble upon them on accident. If your dog does any of these activities, or you live closer to the mountains were the rattlesnakes may be in higher concentration, you should highly consider the rattlesnake vaccination.
The rattlesnake vaccination was developed to protect against venom from the Western Diamondback Rattlesnakes and is most effective against this species. However, here in the United States, many snakes have very similar venom, thus the vaccine may help protect against venoms of other rattlesnake species as well. The varieties of snakes it may protect against include the Prairie, Great Basin, Northern and Southern Pacific, Sidewinders, Timber rattlesnakes, Massasauga and the Copperhead. It may also have partial protection against Eastern Diamondbacks but it will not protect against Water Moccasin/Cottonmouth, Mojave Rattlesnakes, or Coral Snakes.
The vaccine works by inducing the dog or cats’ immune system to generate protective antibodies against the venom when they have been bit. There are some factors that can influence the effectiveness of these antibodies such as the snake species, the age of the snake, the amount of venom injected, the location of the bite, how well the dog responds to the vaccine, and the length of time since the last dose of vaccine was administered. According to the Red Rock Biologics* (the makers of this vaccine), there have been reports that the dogs who have these protective antibodies experience less swelling, less tissue damage and a faster recovery from a bite.
When first getting the rattlesnake vaccine, your dog will get the initial vaccine and then in one month will need to receive a booster. After that initial year of vaccinating, they will just need 1 booster annually in the spring before the peak of rattlesnake season. We highly suggest coming in and starting in April through the beginning of June to get the best possible protection during the rattlesnake season. If you live in an area that has a high population of rattlesnakes, a high incidence of rattlesnake bites, or you frequently visit areas of the country with rattlesnakes, then you may consider boostering that vaccine twice a year. This is because the vaccine is most effective the 1st 6 months after administration and declines in effectiveness after that.
If your dog is immunosuppressed, suffering from a severe chronic illness, or has a history of vaccine reactions, your veterinarian may not recommend this vaccine.
When you are hiking in rattlesnake country, try to stick to hiking on open paths, keep your dogs on leashes to increase safety, and discourage them from digging (especially around logs and rocks). If your home is located in an area where rattlesnakes are very common, keep brush and firewood away from your home and keep grass mowed in the areas where dogs frequently spend time.
RATTLESNAKE BITE TREATMENT
Treatment for rattlesnake bites can be expensive. Treatment may include anti-venom injections that can cost hundreds to thousands of dollars. The use of the anti-venom is associated with an increased risk of adverse effects making recovery even more complicated. Other costs associated with rattlesnake bites include hospitalization, intravenous fluids, and other medications and potentially even surgery. By getting your dog this vaccine, you can reduce the impact of the bite, reduce or even eliminate the need for anti-venom and decrease other treatment costs.
Just because a dog gets the vaccines does not mean that the dog does not need to be taken to the vet in the event of snakebite. If your dog does get a bite, take him/her to your nearest vet immediately. Even if it is a non-venomous snake, the wounds could result in infection. If a snakebite occurs during our business hours, please call and come directly into the clinic. If it is the weekend there should be an emergency vet located near your local area. If you are here in the Ogden area, the Animal ER is located in Sunset. It is in Sunset Square at 2465 N Main Street #5 next to Ace Billiards. Their phone number is 801-776-8118. They open at 6pm Monday through Friday and close at 8am. Saturday they open at 12pm (noon) until Monday at 8am. They are also open on holidays.
If you have any other questions about the rattlesnake vaccination, please feel free to call our office at 801-782-4401.

We are a little late but March was all about Heartworms!
So what are heartworms?
Heartworms are one of the most preventable parasitic diseases in animals. A parasitic roundworm, it spreads from one dog host to another.
How do pets get heartworms?
Heartworm larvae are transmitted through infected mosquitoes which subsequently bite our furry family members. One single bite can give our pets heartworms.
Why should we use prevention?
Heartworms can lead to severe problems with the heart, lungs, liver and kidneys, and can be fatal. In the past we have not had many cases here in Utah. However, since natural disasters such as Hurricane Katrina and Hurricane Sandy, dogs have been shipped around the country from places with higher occurrences of heartworm causing the spread of heartworms from those dogs to ours here.
Isn’t there a treatment if my dog contracts heartworms?
There are treatments. However, they are costly and painful. The only medication used for treatment is called Immiticide. Immiticide uses arsenic in its production, which makes it difficult to reliably carry it since not many people are willing to work with it. Currently supplies of Immiticide come from France. We try to have some in stock but we can’t always guarantee that we will have it if we have multiple cases occur in the same time frame. This last year we had two dogs diagnosed with heartworms within about a week of each other. If we had had a third dog come in within that next month or two we would not have been able to treat them. Another problem we run into when it comes to treating with Immiticide, due to the arsenic in it, it can be very painful to the dog being treated. It has many potential side effects including but not limited to: anorexia, agitation with or without tremors and excessive salivation, fever, depression, possible respiratory reactions to the dead microfilaria and thromboembolism can be observed 7-20 days after treatment.
In what ways can heartworms be prevented?
There are several options that we offer on prevention of this debilitating disease. These include the chewable tablets Heartgard and Tri-heart (a generic of Heartgard) as well as Proheart. Proheart is an injection that will cover 6 months of heartworm prevention. It also treats the common hookworm infections that may be present. Proheart can be more convenient than the Heartgard and Tri-heart because you only have to come in to the clinic every 6 months versus having to remember to give a pill every month but it can be more expensive depending on the size of your pet. If you have a larger dog it could actually be more cost effective to do the injection.
How does the prevention work?
We give our pets prevention monthly. The reason is because the prevention works “backwards”. Meaning that, when we give our pet their dose of heartworm prevention it takes care of any heartworm they may have received in the past month. It only works on the stage of heartworm that is passed on from mosquito to pet. So what if your pet was wasn’t on heartworm prevention and was bit by a mosquito 2 months ago? Or 5 months ago? The best option at this point would be to get your pet on prevention and then in 6 months get a heartworm test.
Wouldn’t I want to get a heartworm test done on my pet right away?
Due to the way that a heartworm test works and picks up heartworms, it takes 6 months from the time that your pet is bitten to the time we can test positive for heartworms. The test reacts to hormones in the worms that can only be picked up on the test when they are adults. When a mosquito transfers heartworms to your pet, worms are in a larvae stage that takes the full 6 months to grow.
Even if you miss a dose of prevention on your pet you should get your pet heartworm tested 6 months from the time of the missed dose to make sure your pet is good to go. You should continue to give your pet their heartworm medication or call your veterinarian if you have any questions or concerns.
