I have a feeling this might be a troll, but I'll answer you honestly. I would like to point out that a "Chorkie" is not a purebred dog. If you don't believe me, look it up on the American Kennel Club website. It's very common for puppies to bite, especially if they are teething. Don't resort to anything like a shock collar, as those are just cruel. I would recommend checking out this article:
