    I need some help with my 2 year old spayed female malamute mix.

    Dog Training and Behavior
    Hi! I have a 6-month-old male Coton de Tulear named Arthur. I have been introducing Arthur to as many dogs as possible since I got him at 10 weeks old. He loved running and playing with other dogs (even big ones) and would never bark at them (I've been told this is typical of the breed)...
