Shirley Dermott, AR 12/21/2009 3:59:05 PM My rescued 10-year old Yorkie had a nauseous odor, thin, greasy coat. After visit with vet, he is bathed every 7-10 days with prescription shampoo, and thyroid meds. He's happier, doesn't spend every minute scratching or chewing himself. His coat has thickened and people now comment on his beautiful coat and happy face. From his previous vet info, he was extensively treated with steroids and no thyroid checks.
