Only bites my husband
I have a beautiful 16 week old yellow lab that doesn't seem to like my husband. At first, it was cute that he preferred me, but recently he went crazy-barking and lunging at my husband with his mouth open. It honestly scared my husband...and made him angry. Tonight, he bit his ear. Hard. I think he might need stitches. I love my dog, but his behavior has him in great danger of needing a new home. He is in puppy training classes and I work with him at home. He gets plenty of exercise and has plenty of chew toys. Suggestions?
