I think the others have given you some good ideas of where to start and it may be that they let him get away with things because he is small. Fortunately neither of my two have had aggression issues. Something else to consider, Snoopy can pick up on those feelings that your GF has of being scared/nervous around Snoopy and that may cause him to be even more agitated/nervous/aggressive. I like the idea of making the dog work for its food. I don't have this issue with regular food but I do make them work for treats. One thing you can also try if Snoopy doesn't like the treats, is to use boiled chicken or even a scrambled egg. He may like that better than the treats and have your GF and her grandma give him some. Good luck!
