I have a 2 yr old staffy. He's very energetic and gets very excited. I've noticed what looks like a clot of blood, the size of a small grape occassionally popping out of his bottom. It only seems to bleed once he gets himself so excited. Could this be piles? Pleas help!

I dont think dogs can get piles ...sound more of a problem with his anal glands a trip to the vet is my advice .

It sounds as though it might be a small prolapse. Best get himchecked by the vet.
