I think a class would be a good idea, but if you aren't comfortable with this one, keep looking. There are lots of ways to train a dog that don't involve choke collars, if that's an issue for you.
Well training him wasnt the issue, he learned all those things in 3-4 weeks, I just want him to have some dogs to play with, our other dog Wiggles is too small for him, he hurts her, and Piddle, whos a little more rough, doesnt like Jasper, just growls and snarls if he comes around...
