Answer
Are your dogs neutered? That needs to be done immediately if it hasn't already. You have two terrier breeds crossed that are both highly energetic dogs. He needs to have a job and a purpose. You need to walk your dogs twice per day LONG walks. Make sure they play at least once a day until their tongues hang out, whether it's fetch or whatever. Get them involved in an obedience program.  Check out the Alpha Dog Bootcamp website for more helpful information regarding establishing pack order in your home.
