He is remorseful, there is no doubt about that. But I cannot stop thinking about the torture that dog must have gone
through. (And I just found out that he has already replaced the dog with a new puppy. Then I get mad at myself for being upset over that too). @Domino: he was just getting home while listening to a call-in show on the radio; he jumped out and ran inside to phone the station, then was put on hold for a very long time.

The dog was not dead when he remembered him, but too much damage had been done by the time he got the dog to the vet, and the dog died overnight.
