Re-posting with rules...I had to delete the last post because people couldn't play nice. So lets try this again...looking at the dogmatic head collars...anyone know if they are any different than the halt? I have a 14.5lb yorkie mix and am not sure if we would be a size 1/2 or 1 from dogmatic. He is reactive around puppies and hyper dogs, he is a work in progress... Please no name calling....I am a dog trainer, 6+ yrs, a member of The Pet Professional Guild...All I want to know is about the head collar. Thanks!
