He's 5-1/2 months. A really good dog, but starting to get chewy...
We got him 7 weeks ago, from a fairly bad situation. But, like I said, he is doing good. He actually passed Basic Ob. his first time through! The only dog in the class to do it and he was the youngest by a couple months in the class, being just 4 months when we started. (But the trainer did not want him in the next class just yet because of his age, so instead of waiting a couple months and having him reevaluated we decided to go through Basic a second time, for socilization and reinforcement.)
Being good in class does not stop him from picking the most expensive shoes in the house to eat.
