I have a 14 month old Chow Chow. We did puppy training classes, level one and two. The trainer suggested we take level two over because my dog will not, stay or come on command. We haven't taken the class again, because he had surgery right after that, twice; then I had surgery, twice. You know life got crazy. What I saw happening in class is that he is a very social dog. When I put him in a sit, and stay, as soon as I walked away, he followed me, or went to visit with the other dogs/people in class. He is very friendly, so I wrote it off to that. But now, I realize just how important it is for him to come when I call. What if he got loose, he now thinks everything is a big game. Help, where do I start? I'm less concerned with the stay command, and more concerned with the come command.
Have you tried letting him out on a long line, and then calling, and pulling gently at the same time? When he gets to you, give him a treat. If you repeat that over and over, it usually works for me. I suggest when he is no longer injured putting him back into obedience again.
I had my little one in puppy class also and we worked on the come command if you have help it will work better what we did: she was put on a long lead then we spaced ourselves out we all had treats and we would take turns calling her to come and treating as soon as she came to us also ALOT of praise it was a game and we made it fun. I still work on it at home and she is doing so much better. I just make sure to have treats or some of her puppy kibble at all times and so far so good. Good luck and just keep working on it, but never call come and if he does not come let it go, go get him so he will know what you want and that you mean it.
We taught the come (or here is what we use) by the direct delivery approach. For a week, at least a dozen times per day we'd walk right up in front of the dog with a treat in hand and say, "[insert name here], HERE" and give a treat. After a week, we tested him while in the yard playing. He was at the opposite end of the yard and I repeated the "here" phrase and he came running. To this day, I have a 100% reliable recall with him....this worked for us because my dog is HIGHLY food motivated.
When God was handing out coats to dogs...the Chinese Crested asked for leather!
We'll I've tried several of your suggestions without any luck. So, Buddha and I are off to obedience class once again! I'm actually looking forward to it, but it doesn't start until late October. I need re-trained, and Buddha will love being around more dogs and people! Maybe we'll get it this time, I just have to work harder on doing homework with him!
