That's pretty strange. How old is he? What do you know about him?
My first thought is that either he has an infection or stones, or he could be from a puppy mill or BYBer - they often confine puppies and young dogs in such a way that they end up living in their own poop and pee. If I remember correctly, the pup then becomes desensitized or something to it.
Or maybe he was marking the bowl and missed? Is he neutered?
Need more information! Definitely strange![/b]
