You bet! There is no age dog that cannot be taught. The “you can’t teach an old dog new tricks” thing is absolutely false! Puppies generally learn quickly and easily because they don’t have deeply ingrained habits yet, but ANY age dog can be taught to be well behaved. Depending on the age and the amount of negative habits that have been learned (and type of dog!), it can sometimes take a little bit longer, but it’s absolutely doable. For example, my favorite example is Willie — a dog in my Therapy Dog class who had never had formal training, and she graduated and earned her Therapy Dog Certification. She was 10 years old when she did it! It’s never too late!
