I said there would be a few posts of my buddy and this is one of them. Recently some type of "bull" dog came near the fence and man...you would have thought he was getting a beating the way he howled at the other dog to get away from his fence. I never heard him sound like that before. He is an incredibly intelligent dog and very territorial and protective. He knows his yard is his. I spoil him I know...and sometimes way too much...but so what. He is a well behaved well mannered dog. He's "My Little One".
