Heather, It sounds as if this dog has had NO training in any department and thinks that he runs the show. Because he has had no training, he has no idea that he is NOT the boss. Because he does not respect authority and/or recognize you as the leader, attempting to train him at this point will be fruitless. BUT... there is hope!! :-) There is a new dog training device called a Gentle Leader. It is a nose loop that somewhat resembles a muzzle however it is *not* a muzzle. It is designed to control that dog that "takes YOU for a walk", it helps control barking, lunging, etc by allowing you to pull up GENTLY on the loop. Pulling up on this loop applies gentle pressure to the dogs muzzle... which is the way that a dominant dog in a pack disciplines it's followers. Further, it is much more humane that allowing the dog to pull and choke. When the dog realizes that you are treating him (humanely) like a dog and you are taking his power away from him, he will be much more obedient in the house, too. These Gentle Leaders are the ONLY type of device that our local animal shelter uses now.... It has been proven 110% effective on ALL the dogs that come into the shelter. Please, don't give up on this dog... Please try the Gentle Leader! It worked for our beagle, too! He no longer drags us when we take him for a walk. You can check out the gentle leader at: http://www.gentleleader.com/pages.cfm?id=19 or do a search for it. Good luck! Renee [Posted in FML issue 4120]
