Yes please help! Nikki is fine until Bear starts barking and growling and then Nikki is like oh ya lets fight! Beacause she knows if she stps on him it would break his back!!!! Bear does not back down! Once a Rottwiler Pitbull mix (verry big dog) tryed to attack me and Bear bit him in the leg and would not let go! I grabbed him and ran! WE got away safe but he will never back down!! I'm afraid he will get hurt! Please tell us if you have any ideals!
