I thought he deserved another break and since I needed to go to Petco anyway, I brought him along. No surprise that he enjoyed the outing, sniffing everything like he's just come to his most favorite place ever in the whole world.
No dogs in the store, though, and I was hoping there would be so I could do a little socialization work. But I did get to do a lot of work with trying to control his excitement and having him stay under control. He did a pretty good job overall, considering the situation. We mostly worked on simple stuff like positions and stopping when I stopped.
He did show interest in people going by, sniffing them as they passed and not shying away or shrinking back. I rewarded him for that and it is a part of socialization so we got a little of it in.
At one point, I think I overstimulated him. I found another cute little ball with some interesting colors while also being "floss" for his teeth (not that he'll likely chew on it, but I figure if I play with it with him and making him bite and pull on it to get it from me...) and I was telling him to get it and getting him excited, and he was slipping around on the floor trying to change directions and get the ball and looking around! He was just super excited and wound up - eyes all big and just didn't know what to do with himself.
Of course, he loved being around the food aisle and sniffing the bags of treats. I don't know if this counts as object discrimination, but he got to pick out which treats he liked best. He kept showing interest in one pack first and most often, so that's the one I bought for him. When I gave him some, he certainly liked them.
So it was a kind of a light day. No "formal" training, but threw some in and he got out of the house and to explore a fun place. He was pretty tired from all the excitement.
