I have a6 month old Lab puppy who has recently become scared and jumps up and bites my arm. She is never aggressive to anyone else. I think it is related to seeing other dogs as she appears to freeze now when she sees one in the distance. The only thing that stops her is if she hears a different dog bark although she doesn’t see it.
