Hi everyone, I am posting something because i am at lost right now. I have a 5 month old samoyed puppy and i love him so much. He is really nice and quiet inside the house, love to learn tricks, very much food motivated... Overall a pretty easy dog to live with... Expect when I take him outside, every singe time i take him for a walk (multiple times a day) he got crazy. He usually walk fine and suddenly comes behind me and starts biting my ankle and calf, then it escalate to biting my arms, thighs, hands and sometimes jumping to bite my face. At this point nothing i can say or do matters anymore, he doesn't care about treats, doesn't respond to any commands, i tried to turn my back at him but he doesn't stop, i said NO and STOP loud and clear but nothing worked... I am open to any suggestions because i have really badly bruised legs and i start to be anxious every time we have to go out. Thanks if anyone have suggestions!
