we have a 1.5 year old Pyrenees. He loves us and our kids, he is my baby. However, he has shown some aggressive tendencies with our other dog (only food driven)and now with my husband. The incident was over a spot on the couch. My girls are scared of him and I do worry about what would happen if he went at one of them. He was very aggressive at the vet recently also. Normally a big loving dog though. I am heartbroken and don't know what to do. I am looking for help and advice ASAP please.
