Everyone knows the saying “You can’t teach an old dog new tricks”. I am here to say that that is untrue! Dogs have a wonderful ability to live in the moment which means that if you change, they will change (for more on this concept click here). As a dog gets older, its energy level lessens and their joints become more achy so you may want to re-think introducing your senior to the sport of agility or trying to teach them to “sit pretty”. But especially in the realm of behavior there is no earthly reason why your dog should not learn to behave even if they are 18 years old. Lead your dog!
