Oh I had not thought of that.
Yes he seems pretty underweight. The condition he was in - it took TWO shampooings with soap and 1 with flea meds to get him clean!! It wouldn't surprise me if that's what I'm looking at. It's tough to see it well in the pics but his right leg in particular is bowed.
If he was a Puggle type he might be that way?
His legal hold time is not even up

but I could not stand to see him there in the shelter, and Steve offered to send him home with me, I am glad, in retrospect, that I did. No puppy should live as filthy and flea bitten as he was...
