I want to recommend Ocu-Glo eye vitamins for everyone's dogs. They are pricey, but since they saved my Coco from going blind from retinitis and allowed her to have some vision the last two years of her long life, we've given them to every one of our dogs. They've all gone back to their Creator with clear, bright eyes. The recommendation was from the Doctor of Ophthalmology at Georgia Veterinary Specialists in Atlanta. It's 100 percent worth the money. http://www.ocuglo.com/
