Rattlesnake Bites With warmer temperatures on the way to Grant County, the chances of your pet meeting a rattlesnake increase. The US has 16 different species of rattlesnakes. Most rattlesnakes are found in the southwest but territories extend in every direction of the compass. Most states have more than one variety of rattlesnake. The rattlesnake is found in wetlands, deserts and forests from sea level to mountain. Rattlesnakes serve a very important role in nature. They are among the most highly specialized creatures on the planet. Rattlesnakes eat many of the smaller animals, such as mice. Mice are responsible for crop damage and for spreading many diseases such as the Hantavirus and the Plague. Unlike common belief, rattlesnakes are NOT aggressive, malicious or evil. A rattlesnake will only bite when threatened or to feed. Being smaller than most everything except their chosen prey, they threaten easily. Given a chance, a rattlesnake will leave a threatening situation as rapidly as possible. They do not choose confrontation but, if they feel cornered, they will bite to protect themselves. A larger animal or human are never considered prey, only threats. Rattlesnakes annually bite 8,000 people, with 12-15 ending fatally. The number of pets, especially dogs, bitten or killed each year is not known. Experts feel, though, that the number is in the thousands. What is rattlesnake venom? It is actually toxic saliva. It is composed of an array of complex proteins. Venom contains more than one toxin that combine to be more potent, in effect, than the effects of each individual toxin. Most toxic effects are a result of the enzymes found in the venom and, so far, there have been 25 enzymes identified. Venom causes severe pain, cell death, numbness, diminished function and can cause the loss of a limb or life. Local effects of venom are inflammation, damage to blood vessel lining, clotting defects and tissue destruction. Some venom can cause paralysis due to neurotoxicity. How can you protect yourself and your pet from being bitten by a rattlesnake? While walking, control your pet with a leash. Don’t allow your pet to run unrestrained. A leash is your pet’s best safety device. Don’t allow your pet to explore holes in the ground, under logs, flat rocks or under planks of wood. A dog poking its nose into every mysterious hole in the ground, sniffing under downed logs, digging in leafy patches on the forest floor…are all opportunities to discover a rattlesnake. Stay on open paths. Snakes avoid open areas where there is little protection from predators. Open areas give you an opportunity to avoid a visible snake. Keep nighttime walks to a minimum. Snakes are nocturnal. If you hear a rattlesnake, keep your pet at your side, locate the snake and move away. Off trial hiking with an unleashed pet may stir up a snake and you could become a victim as easily as your pet. If your pet seems unusually curious about “something” hidden in the grass, back off your pet immediately. Don’t allow your pet to harass other animals. Never attempt to pick up or kill a rattlesnake. Most people are bitten while engaging in these activities. A rattlesnake bite will make dogs very ill and can do serious damage and can be fatal. Fortunately, rattlesnake bites do not happen very often. If your dog has ever been treated with rattlesnake antivenom, your dog is at risk. Antivenom is made from blood serum of hyper-immunized horses. A single dose of antivenom can make dogs so sensitive to the serum that another dose of antivenom is rapidly fatal. Dogs that have been treated with antivenom once should never be treated with it again. Antivenom treatment can cost hundreds to thousands of dollars. A rattlesnake vaccine recently became available for dogs. Why not vaccinate your dog? While the vaccine will make your dog resistant to rattlesnake venom, it will not make a dog immune. Resistance is not 100%, it is still possible for your dog to be injured or killed from a rattlesnake bite. Avoidance of rattlesnakes is the only 100% guarantee. As with any immunization, your dog can have an allergic reaction. Most vaccine reactions are mild and easily treatable, but rarely, vaccination reactions can be serious or fatal. Why vaccinate your dog for rattlesnake bites? A vaccination makes sense if your dog has a high risk of being bitten. A dog vaccinated with the vaccine will be much less likely to suffer permanent injury or death from a bite. If you live in a neighborhood with lots of rattlesnakes, ever had a dog bitten before, take your dog hiking in the mountains and don’t use a leash or will be visiting an area that might have rattlesnakes, a vaccination will help provide resistance. If your dog has ever received antivenom, you can eliminate the risk of fatal antivenom sensitivity by vaccinating. The rattlesnake vaccination is administered in two injections a month apart, the first year, with annual boosters each year after that. Cost is usually about $18.00 per dose. Boosters should be administered in the spring or about a month before your dog is going to be in rattlesnake territory. The vaccine stimulates your dog’s immunity system to produce antibodies. Vaccinated dogs will suffer less pain and have a reduced risk of permanent injury from rattlesnake bites. If your dog is vaccinated with the vaccine and is bitten, be sure to have your veterinarian evaluate your dog as soon as possible after the bite. Infections are still possible. Your veterinarian, also, needs to be sure your dog has enough antibody protection for the specific species of snake that has bitten your pet. Additional medical treatment may be necessary. Is the rattlesnake vaccination the right choice for your dog? Talk with your veterinarian for more information.
