Welcome to YT! Blake is going to be a handful for a while. He's a baby and he's teething, learning his boundaries, searching to discover his world. I'm not going to tell you it is going to be easy. It's not. Terriers are a stubborn breed.
But soooo worth the time put in. I promise. Just hang in there. As mentioned above, just as you would with a human child...these pups are time consuming and sleep depriving. You'll get there though.
Come here for moral support and ask any questions you have. We will be here for you and Blake!
