After 3 walks with the pinch collar, it is my considered opinion that Tika might possibly be pulling less often and less hard, maybe. Kind of like Rem, mostly disdainful of my attempts to discourage pulling. Dang "hard" dogs.
Rachel said that Tika was almost wonderful in class today because she came back to me fairly quickly each time she ran off. Of course a couple of times Rachel tossed large jump bars into the grass near her to startle her first. I, naturally, see that she runs off *every* run, every dag nabbed one, rather than sticking with me. Didn't used to do it nearly so often. All after that family of squirrels tortured her (personally, of course) for a couple of weeks a couple of months back. We haven't seen them since; don't know what she'll do if they ever return!
One of Tika's classmates was injured, so his handler borrowed Jake today. He was such a good boy. Folks commented how good he looks and how well he's running. Got the appropriate satisfying oohs and ahs when I said he's going on 12. BTW, if I didn't already mention it, there's a movie of us doing a moderately fast jumpers course at http://agilityinmotion.com/. Click on Dog Agility Movies, then scroll down to April.
