Pet Care: Canine needs geriatric careDear Dr. Fox: Our 17-year-old Maltese is failing. He has limited vision and hearing, and his hind legs and hips are weak. We feed him your home recipe, but lately he can’t seem to keep it down. We find bits of brown rice in his vomit, and his stools are loose. We took him to the vet, and he suggested a bitter-tasting medicine to stop the nausea. We’re hesitant to give him any more drugs. The last drug for incontinence made him very sick.
