Rattlesnakes are venomous serpents that are found throughout North America and elsewhere. They can live in most climates but are especially plentiful in the southwestern United States.
Rattlesnakes are pit vipers, which means that they have a small indentation, or pit, between their eye and nostril. This is a sensory organ that detects the heat of the rattlesnake's prey.
Rattlesnakes live in dens, which may be holes in the ground, crevices in rocks, or hollowed logs. In cooler climates, they hibernate during the fall and winter seasons. They are not nocturnal, but in hot weather, they are often more active at night.
A rattlesnake's venom is meant to kill its prey. Most rattlesnakes' venom is hemotoxic. This means that it affects the integrity of the victim's blood vessels, resulting in pain, tissue damage, and internal bleeding. If the bite is on the throat or face, the resultant swelling can cause death due to airway closure as well. Some rattlesnakes have neurotoxic venom, which attacks the nervous system and results in paralysis.
Rattlesnake Bites in Dogs
Dogs are especially prone to rattlesnake bites because they are curious, often nosing around in logs, under rocks and leaves, and in holes in the ground. They may also feel protective of their humans if they come across a rattlesnake during a hike and attack it in defense of their person.
Rattlesnake Treatment in Dogs
The treatment of rattlesnake bite in dogs includes the following:
Many dogs die each year from rattlesnake bite, and many more are permanently injured.
Rattlesnake Vaccine for Dogs
Red Rock Biologics provides a rattlesnake vaccine for dogs. It was approved by the USDA in 2004. This vaccine is designed to help the dog develop antibodies in response to the appearance of rattlesnake venom in the body. These antibodies can result in less pain and tissue damage in the area of the bite, more time to get to a veterinary clinic after a bite, and potentially less need for antivenin and other treatment.
This vaccine protects against the venom of the Western Diamondback rattlesnake. It may provide some degree of cross-protection for the venom of several related rattlesnakes, such as:
This vaccine does not protect against the venom of the Water Moccasin, Mojave rattlesnake, or Coral snake (Red Rock Biologics).
How Well Does the Rattlesnake Vaccine for Dogs Work?
The vaccine is not fully-protective; it will not completely mitigate the effects of a rattlesnake bite. How well it works for a dog that is bitten by a rattlesnake depends on the type of snake, the amount of venom delivered during the bite, the size of the dog, the size and age of the snake, and the location of the bite. However, dogs that are bitten by the types of rattlesnakes listed above often experience less pain, swelling, and faster recovery when they have been previously vaccinated.
Snakebite is always an emergency, even if your dog has received the rattlesnake vaccine. You should take your dog to the veterinarian immediately if he is bitten by a snake of any kind. Your veterinarian will determine whether your dog needs anti-venin or any other additional treatment.
Getting the Best Response from Your Dog's Rattlesnake Vaccine
The effectiveness of the rattlesnake vaccine can be increased by adhering to the following guidelines:
Consider the vaccine even if you do not live in a rattlesnake-endemic area if you plan to take your dog to such an area for a visit or part of the year.
Safety of the Rattlesnake Vaccine in Dogs
This vaccine is licensed for use in dogs in the US. There is a different vaccine licensed for horses. There have not been many side effects reported in conjunction with this vaccine, according to Red Rock Biologics. They report the following side effects:
The rattlesnake vaccine should only be given to healthy dogs. Your veterinarian is best-suited to evaluate whether your dog should receive the vaccine, how many initial boosters he needs, and how often the vaccine should boosted after that.
