You have the choak collar on him... No wonder he is crazy.
believe me, i kinda think he needs it. he's a young australian cattle dog. totally bonkers. i personally wouldn't use a choker collar on a dog i owned...
i was walking him earlier and this old lady asked me "is he blind?" cuz of the silver/blue eyes. makes me want a dog like this, but nahhh. too nuts.
Maybe he's really a Dingo and they are just telling you that he is a cattle dog.
we call him a dingo sometimes. i don't think he's got dingo in him. he's be more ferocious.
