I have a positive update! Last night when I got home from work, Husband and I took Lexi for a walk around the golf course. I walked her for awhile until I was sure she was exhausted and then let him take over, hot dog pieces in hand. She did GREAT! She was sitting for him and leaning on him as we walked!!!!!!!!! I am still a little weary but I think with time and walking her together nightly we should be able to have them trusting each other again. But for now I am keeping the fridge stocked with plenty of cut up hot dogs!
