Blanca wound up on quite a cornucopia of medicine: the monthly heartworm pill, of course, but also Rimadyl for arthritis, Thyroxin for her hypothyroidism, Benazepril to fend off kidney trouble, Glucosamine to keep those hard-working joints moving, and the occasional course of Cephalexin to fight the ear infections. I wound up with my hand down her throat every morning and every evening. She'd clamp her jaws shut, but quickly relent.
