I heard “you can’t teach an old dog new tricks?” Is this true?

Certainly not! Dogs, like many species, are able to learn throughout their lifetime. It is never too late to help a dog learn new behaviors. However, just as with people, dogs are creatures of habit and can get “set in their ways” as they get older, so training may take a little more time than training a puppy, for whom everything is new and different. If you’ve ever gone back to school or taken up a new activity in your adult life, you know you can succeed with time, especially with the rewards it will bring, so go slow and reward your dog as she learns the things you want her to learn.
