Sometimes you think about placing him elsewhere. You think you have a lot of problems. Relax, you only have one. Your dog is alpha. Use your eyes assertively, being sure to make him look away first in a test of wills.
Alpha has to do with being in charge.
Everything in your house, including your dog, his toys, his food, his bed, everything belongs to you. You say what does and does not happen in your house. Start with his food. Make him sit and wait while you prepare their food. You should also be able to stop him and take the food away at any time without him showing you any kind of resistance or aggression.
