I have an Old English Sheepdog puppy 11 weeks old. She is showing some signs of aggressive behavior. When she is picked up from laying down on the floor and held like a baby she growls. My daughter-in-law has a bloodhound/lab puppy that she plays with and they take turns stealing each other's bones. My husband came up behind her and attempted to pick up her bone and move her to a different location and she growled and snapped at him. What do I need to do?
