Hey everyone! I'm starting Grover in beginner obedience next week and I want to make sure we're on the right track. Grover didn't go to puppy classes, for a variety of reasons, it just didn't ever work out. So he'll be 5 months in 2 weeks and we're just diving right in. He knows sit and he can walk on a leash fairly well. Do you think we'll be behind? I ask at the place and they said no. But I'm worried because we've only ever trained Grover to a leash with a harness and the classes require that you use a collar. Another question, they mentioned that they sometimes recommend that you use a pinch collar for training. Is this okay? What have your experiences been with this? I feel if-y about it, but it seems that a lot of trainers recommend it? Thoughts?
