 Hi, it's Alan Cable with another dog tip. I have a friend who came over for a visit last night. Her daughter's pregnant, and she was trying to get the dog in the kennel when he put his teeth on her arm. So this friend adopted the dog, which is a smart idea. It's never okay for a dog to put his teeth on you. In fact, from a very young age, you've got to teach your dog that. No teeth on humans. It's a real good idea to teach your kids all about dogs. How to behave and act around them, especially strange dogs, and how to approach to say hi. Typically, a dog is going to warn you before he bites you.
