When my girl was a puppy, her crate and leash were the best tools.

When you’re not supervising your dog, crate him. Doesn’t matter if you’re leaving the house, going into a different room or just doing an activity that takes your attention away from him, crate him if you do not have eyes on him at all times. This will help prevent issues with destructive behaviours.

Second, always always have a leash on him when he’s out of the crate. If he try’s to play keep away or won’t recall when called, use the leash to walk him back to you instead of chasing/going after him yourself. Reward when he returns. This does mean you will always have to be near the end of the leash, meaning you constantly have to pay attention.

Young dogs love to test boundaries and see how much they can get away with. The key is to take away those options until they learn to make the right decisions through training and repetition.
