Colorado is home to many rattlesnakes. Every year, veterinarians treat dogs that have been bitten on local hiking trails. In fact, a dog died from a rattlesnake bite in Castlewood Canyon State Park back in 2011. But you can help your dog avoid a potentially deadly encounter by attending a Rattlesnake Avoidance Clinic. It’s being featured this weekend at the International Sportsmen’s Exposition in Denver. You can register for the training at ColoradoGunDog.org.
