Just want to comment on your posts.........great.........We have had some aggression problems at home when our recently rescued newf came into season and she decided she would kill our female dog, Tessa. Even just pulling is often the worst thing to do. We found a "hind quarter yield" by tap or push was the greatest help to disengage our dogs, if you got them at the early part, before the fight. We are also heavily into dog training. We have been told by our dog trainer that he finds horse people the easiest to work with. Our dogs are now happy and at peace. They walk off lead, no tricks, in company and now socialize well with all other dogs and horses. Hope to see more of your posts, cheers Ronnie Taft
