My roommate recently brought home a 10 week old female half blue heeled, half lab puppy. I have never lived with a dog before, but to me she seems extremely intelligent. She picked up sit and come before we had her 2 days. She seems very happy, and her training is productive and fun, but because of our inexperience, we have thought about attending professional training. The issue is that when i looked at the credentials of the trainers at the obedience school closest to us, he first thing mentioned is "remote collar training certified". This has left me with a lot of questions. Is shock collar training humane? Will attending a class with shock collar trainers help me if I will not use the same techniques at home? Are there places out there with trainers that will help us with purely positive training? Ignoring Arya is the only "punishment" she has ever received, and with how well it has curbed her nipping, I'm fairly certain neither my roommate or I could bring ourselves to use a shock collar at home. Is this common practice at obedience schools?
