I tried to send a similar message before but appeared to fail, so sorry if it comes through twice. I was telling my daughter this morning about the Surgeon/ Hannify's Impact episode. She asked me the question "can you stop a dog from fighting". I decided to not go down this track as you might understand including offering up the "ultimate fix". Anyway it prompted me to consult other members as to whether they have had any success and/or known of other trainers who have had notable success with fighters as compared to dogs who were more your "playful non-chaser". Obviously, appropriate discretion is required. I have in years gone by seen dogs with blinkers attached to the muzzles. Not sure if they worked. You can imagine how enthusiastic anyone would be about trialling your greyhound with one of those dogs, ha ha. I think they needed to bring their own trialling companions. Any advice/comments/stories would be appreciated.
