This is an over the counter product - it does not require prescription.
NUPRO All Natural Dog Supplement was researched and developed by a nutrition doctor. It is a totally holistic product that replaces the vitamins, minerals, and digestive enzymes that a dog does not get from his processed food. In other words, what we are doing is replacing with natural ingredients what a dog would normally have gotten in the wild. It is excellent for all breeds and all ages from puppies to geriatric.
