Hello!
I have an 8yr. Old doberman who I love to death but for 3 days she hasn't been eating her food and she has been urinating a lot! Can anyone tell me if theirs anything wrong? Thanks

However a sudden loss of apetite like that nearly always means a physical problem. Get her to the vet before the weekend.
