OK on all and thanks everyone. We have been feeding him the Costco dry dog food - Natures Domain - salmon meal and sweet potato. Several of the adopters use it, and they say it is good. He is settling down little by little, and we understand that he is a very young dog. He raced in 28 races, won 2, and placed 2nd seven times. Yes we have given him treats from the counter and we will stop that now - still learning. He doesn't put his paws on the counters, just runs his nose back and forth on the front edge.
Another question, do they get bored? We take him out for walks a couple of times per day for about 15 minutes each walk. But past that he is on his bed, not necessarily sleeping, but just hanging out. Of course he still follows us from room to room, but he is gradually slowing down on this, as he sees there probably isn't nothing interesting going on there. He walks wonderfully on the leash staying right by my side.
All n all, we love him!!
