"My three-and-a-half-year-old cocker spaniel barks nonstop when people come over to our house. She recently recovered from autoimmune hemolytic anemia and has since become extremely protective of my husband and me. The dog has never bitten anyone, but with the tone of her bark, I&amp;#039;m afraid she may someday \u2014 my worst nightmare. Would it help to socialize her, or is she too old? Socializing her will definitely help, but I feel you should have a professional consultation. Choose someone like a behavior modification specialist, who can diagnose her as aggressive, fearful, or just very vocal. Once that is established, a behavioral modification plan can be put into action to treat this issue once and for all. "^^<http://www.w3.org/2001/XMLSchema#string>
