Beautiful dog and we hate that we need to rehome him. He did bite the neighbor. We all feel it was protective based but the neighbor is afraid of him. We agreed to get rid of Walter. We haven't tried training. He is very smart and learns fast. I indicated that he is good with kids and adults because he is awesome with our family. He has growled at adult females and children but no biting.he was not socialized appropriately because of our schedules. He is mostly at home with family and now is territorial and protective.
