I'm pleased to inform the forum that Shandy,our problematic lab is now a wonderful dog. He is not without all his problems but they have diminished by 90 percent at least. Yesterday was a huge,huge day for all of us. Shandy was muzzled and we took him into B&Q. He was a thorough gentleman at all times and lay down on the floor when my wife and I had to study something. No lunging, he was not anxious. The only problem was stopping people wanting to pat him. He now loves my wife and son. Gets so excited when my son comes for a visit and walks with him with no problems.
