I have a 2 year old female english staffie. She is a very timid, anxious nervous dog. Today my wifes father was at our house and is pretty much a stranger to my girl Jess. She got nervous around him and bit him on the leg. he got a fright and jumped back she reacted and began barking and biting him until I pulled her off. I have a de sexed male english staffie and he is wonderful and wouldn't hurt a fly. He is older than her but she seems to be alpha dog and bosses him around. she was the runt of the litter. We have 3 kids and she has never snapped at them or my wife and I but she has at some of my kids friends. Please any advice on this would be so grateful. We love her so much and she is my baby girl but we can't have this continue.
