Vitamin B-12 Methylcobalamin 5 mg (100 sublingual tabs) 2DOCS pet supplements are designed around the simple principle that dogs and cats are just as physiologically complex and in need of nutritional supplementation as humans. A dog’s dietary needs aren’t exactly the same as a human’s, of course, but the underlying nutritional building blocks are. Dogs and cats require the same vitamins, minerals, essential fats, and proteins as you do, and sometimes suffer from the same sorts of conditions as people: allergies, joint problems, diabetes, and gastrointestinal disorders.
