Hello I've decided to start training Ollie to walk on a loose lead. he has a good idea what the heel command means and can walk by my leg for about 40 seconds at a time at the moment. However I'm undecided what to teach him with; a harness or half check collar. At the moment, I'm using a harness which has a front ring so checking him means he gets pulled round and stopped in his tracks, which works well. After a few checks, he'll walk by your side and stop when you stop. However I've always dreamed of walking a dog with just a collar, and always liked the idea of half check collars as they do a better check than with a normal collar. Although he will always need to wear a harness due to him being on a flexi lead/longline so is it worth just loose lead training with a harness (with ring on the back)? And I don't want anyone to say that I shouldn't "check" dogs. Ollie is a stubborn, strong willed dog and he needs a firm hand, and checking is what is needed to get the point across. He won't walk on a loose lead with just treats, he needs checking too. (tried teaching loose lead walking with just treats, so I know he won't do it).
