Venomous snake bite in dogs
Most venomous snakebites in North America are due to Pit Vipers. These include rattlesnakes, pygmy rattlesnakes, Massasauga, Cottonmouths and Copperhead snakes.
Brown Snake envenomation is the most common envenomation in pets in Australia. The exceptions are in Victoria, where Tiger Snake envenomations are more common, and Tasmania where there are no Brown Snakes and Tiger snake bites predominate.
Generally pets are bitten during the warmer summer months. Rattlesnakes are cold-blooded animals and so they prefer hot arid environments such as the desert, sand hills, grassy planes or rocky hillsides.
