I missed this thread when you first posted, but wanted to pop on and say what a wonderful transformation! Prince is certainly very lucky to have found you. I've been following your various posts with him and you have done a brilliant job. Not many first time owners would have the sense and tenacity to deal with his various problems, and in turn solve said problems. He looks in great shape, what a lovely shiny coat he has now!
Looking forward to seeing more from you and Prince
