I agree, If your dog is doing well in the environment with the elderly don't worry what anyone else says. Keep doing it! From an experienced background in pet therapy though I can tell you that most puppies are not suited for therapy work. They are still little rambunkous balls of fur that get really excited around people or especially other dogs. One year old is when your average dog is able to do basic obedience commands consistenly enough to pass the TDI (Therapy dog international) test. Remember also that most people who do pet therapy volunteer their time in nursing homes and their dogs do not get on the job training! You are fortunate to be able to take your dog to work and not have to put it in the kennel all day. I personally am not that lucky. I also think that a puppies personality is not the same as it is when it is mature. This is just plain common sense. Are you exactly the same as you were when you were a child? You learn from experience which shapes your personality throughout your life. A pup is no different. They learn from experience, they lose the childlike exuberance and become more adult minded, intelligent, and know better right from wrong. This is not to say their personality is not similar to what they had when they were pups. It just means it is added onto with experience. Keep up the good work making the lives of people who can not have a pet of their own richer and filled with bundles of furry love
