This just makes me sad and angry

But I will have to talk myself into the fact, that because the pet store is still out to make money on this poor pup, they won't put him down. They will just turn around and sell him to another unsuspecting soul. Poor little guy! Sorry, but I would have kept him and taken this as a sad lesson well learned: DON'T EVER, EVER, EVER BUY A PUPPY FROM A PET STORE!!! EVER, EVER!!!
