We are taking him out for a run three times a day instead of just two, also we are making him do things more often, like sit and lay, when I walk him on his leash if he pulls me I make him sit down, wait a few mins and they tell him ok.

He is such a smart dog, very quick to learn.
We recently learned that he knows a game with his treats, we rub a treat on both hands then put the treat in one hand behind our back, then we put our hands out closed fist around the treat and make him pick which one it is in, he puts his paw on the hand it is in ans we give it to him, he is very gentle about it as well. Very smart dog, we are all very glad to have him in our family !
