I need help!! We have Henry, a 6 year old 10 pound yorkie. About 2 months ago we adopted Scotty, 10 lbs, 9 months old now, from a yorkie rescue. Scotty, every once in a while for no apparent reason attacks Henry and starts a big fight. Scotty bites Henry, then it turns into a terrible fight and we have to pull the dogs a part and separate them. It is so awful! I have taken Scotty and pulled him down the ground and tell him no. Could Scotty be jealous of Henry? We give equal affection to both. Also, sometimes when Henry is eating, Scotty will just attack Henry for no reason, barking, biting and growling and snarling at him!! If anyone has any advice, I would so much appreciate it! I don't know what to do!! Thank you
