We tried few classes, but we had no luck. Richie was the smallest dog in the group at that time and he just couldn't participate in everything. We also had a"personal trainer" once, but the lady was smoking non-stop and was quit harsh to him, I mean that was too much in my opinion. I guess, in our country this kind of things are just not well-developed yet, but good luck, it might be very helpful!
