Ahhhh...honey, I think you came to the right place for support and guidance.
Has Criket seen a specialist yet? As for money to pay the bills, have you applied for Care Credit yet?
I do believe that he and you will adjust one way or another. My friend has a little Yorkie that has a deformed rear leg, it kinda hangs there, but she adjusted and really does quite well.
As far as the fecal part, well, you can certainly look into diapers
Keep us posted
