German shepherd

This is your German Shepherd Archie, he knows a lot of commands, from the basics to the most important ones. You have been training Archie since he was a baby, you had a lot of time. Now you are training him too, you buy him a lot of toys, a lot of treats, you perform commands with him and he does them all just as perfectly as when he was a baby. You often walk the streets with him, sometimes you walk where there are few people, and sometimes where there are many. All people admire this dog. He is 3 years old.
