Ohhhh, he is so cute! Poor little guy, I hope he gets well soon! and bless your heart for taking him in - he'll have Larry and Rita in fits, pretty soon, as puppies always do
I'm going to guess Shar-Pei, with all those wrinkles, or bloodhound - ? But he is still so young and when he is older those bones and skin will lengthen out a bit.
As far as names - in keeping, he really should have two names, like Billy Bob or Bobby Ray or Jimmie John or somethin', but I don't think he's big enough for a handle like that, yet
Oh, yeah -
