Last week I rescued a 4 year old Tri male from a puppy mill situation. He is horribly underweight but getting better. I can't count every rib just by looking anymore. I am having him neutered next week. He also has to have extensive dental surgery which I'm having done at the same time as the neuter. He is terribly stained from living in his own filth for so long. Does anyone know of anything I can use to make him white again? We won't even get into the smell, I know that will eventually go away. Poor little guy is just the sweetest thing. It breaks my heart that he could have been treated so bad.
