In parts of the U.S. where venomous snakes are more common, training programs aim to protect pets from getting bitten. The American Society for the Prevention of Cruelty to Animals says up to 150,000 dogs are bitten by poisonous snakes each year. One emergency vet in Tucson, Arizona, says her hospital treats four to six dogs for rattlesnake bites daily, and the occasional cat. With quick treatment, the survival rate for pets is 94%. Snake-avoidance trainers say using electronic collars sparingly teaches pets not to approach poisonous snakes. The ASPCA says the collars should be used under the guidance of a knowledgeable trainer. Other steps to avoid pet-snake interactions include trimming back undergrowth and learning about snakes in your area.
