I love the days when I get the Duo together for our evening hike.
He hasn't set ground rules about playing intensity for Shyla yet. So, I interrupt them, and have them doing a little obedience practice whenever R starts acting reticent about play. Interestingly, R did set the rules about a tennis ball that he was holding. When Shyla tried to take it from him, I heard a low rumble of a growl from R, and Shyla quickly retreated to the other side of the room, leaving R to enjoy his tennis ball. That tells me that R will set the rules about things that are important to him, and Shyla will follow them.
This was just after I'd called them. Shyla was a little faster out of the blocks.
We will keep practicing recalls for our dogs' entire lifetimes. Because recalls are so important to their safety, the dogs always get an amazing jackpot of treats for a fast and enthusiastic recall. For other behaviors - like sit, stay, down, and other basics - we fade the treats with time. Both dogs only occasionally get rewarded with treats for those behaviors. But they always get praise!
Our last two socialization training sessions have gone, for the most part, extremely well - after she had such a dramatic setback post-spaying a few weeks ago. I'm certain that there will be more backward steps in our future because that's how this process goes, according to people more experienced than me. But it doesn't matter in the big picture - I love this girl for who she is, no matter whether she acts fearful or outgoing.
