My trainer at Canine Companions for Independence just loaned me a Back Dog training collar that she got in Australia. My pup had a sore near his eye from the Gentle Leader that rode up on him. NO knock on the GL as different dogs have different head structures. He seemed to not be as aggressively trying to remove the BD harness as he was with the other halter. Our boy does happen to be a BLACK DOG. we would love to be able to get Black Dog T-shirts from AUS. you should add them to your inventory (www.mytrainingstore.com)
