I am so glad to hear Moses is doing well after surgery. Sorry he lost a leg....but I have seen so many dogs do well with only three. And no matter what you are his Mom and no one better to love and care for him than you. You made the right decision for your situation. Me and my Belle go back to the vet for a re cast and check up tomorrow. Hopefully, her heel is healing well and we wont be faced with the same decision, but if so than we will love her even more so...just as your Moses. He is blessed to have you. I'm so sorry that someone would suggest you turning him over to a rescue. He is yours and you will care for him the best.
