I've been working on a 'leave it' command with my dog thinking it might be useful somehow in dealing with his leash reactivity. We've only practiced the command indoors in a controlled environment and we've only practiced with low value treats. Today on our walk he ran across a chicken bone. He picked it up right about the time I realized what it was. I fully expected to be prying that bone out of his mouth, but I tried 'leave it' and I'll be darned if he didn't drop that chicken bone back on the ground. He just stood there staring at it until I gave him a bunch of treats, but I'm kind of amazed that it worked at all. I'm so proud of this guy.
