On Sunday morning we went to a park which is popular with families with little children. We walked around and I gave treats to Cai for looking at children doing "strange" things. We saw kids roller blading, wading into a pond, running, swinging, hitting a large rubber ball against a wall, and pushing or pulling wagons and such. We heard hids yelling, laughing, and crying. The only thing that spooked him was a girl who was wearing roller blades and a helmet and was swinging on a swing, facing toward us. We moved farther away and then played Look at That. He's getting the hang of it -- sometimes he looks at people and then pointedly looks toward me and steps toward me.
This morning's socialization trip was to Urban Ore, a scrap yard/second hand store for all kinds of home construction and decoration items, such as toilets, sinks, doors, windows, scrap wood, chairs, etc. We passed by a tiny rocking chair and I asked Chimera to put his front feet on it for a treat. He did, and then decided on his own to jump all the way onto it and sit down! I started feeding him handfuls of treats to reinforce the behavior and get him to stay long enough to take a picture:
Back at home, he went into his crate for three hours while I did dog walking. He didn't cry when I got home, even while I showered, until I was done and went into my room and he saw me. Progress!
