Dog Vitamins and Supplements
If you pop a multivitamin every morning, should you be tossing your dog a canine supplement as well?

Vitamins and minerals are essential components of a dogs diet. They govern many processes in the body, including regulation of heartbeat, ability of the circulatory system to deliver nutrients to the body, and neural activity. High-quality dog foods are specifically formulated to deliver all the nutrients dogs need to stay healthy. Why then do manufacturers produce so many different dog dietary supplements of vitamins, minerals, herbs, and other substances?
Some dogs have special needs such as a weakened immune system that make supplementation a smart choice. Many people claim that supplements have helped their dogs overcome chronic diseases or have alleviated their symptoms. Some dog owners may choose to use supplementation as a preventive measure against future health problems. But some vets advise against supplementation because dog foods are nutritionally complete and certain vitamins, minerals, and herbs given in large doses may be harmful to some dogs. Other vets worry that processed commercial dog food has lost much of the nutrition present in the original ingredients and that supplementation is an important safeguard against deficiencies, some of which may be too minor to detect but which could eventually lead to chronic health problems. Supplementation, these vets argue, is a safety net and will not hurt dogs as long as their owners administer supplements according to package directions.
Supplement manufacturers and many holistic veterinarians argue that supplements aren't effective unless given in doses more exacting than those in dog foods; it can be difficult to determine how much of a supplement a dog actually receives from a bowl of kibble. In supplement form, vitamins, minerals, herbs, and other substances can be administered in the exact dosages appropriate for different ages, weights, and breeds of dogs.
According to regulatory agencies like the FDA, dog supplements fall into a gray area between food and medicine, and many of the ingredients in these supplements are unregulated. Proceed with caution and give them to your dog only under the guidance of a veterinarian who is knowledgeable on the subject. Even if herbs are legal and saleable, they aren't always safe for every dog in every situation.
Supplements that contain the same vitamins and minerals found in food may seem safe, but this isn't always so, either. For instance, dogs store fat-soluble vitamins like vitamin D in their bodies. If they ingest too much of it, the vitamin can accumulate to the point of becoming toxic. Supplements of water-soluble vitamins like C and E probably are less likely to cause a toxic reaction in dogs because they are typically eliminated from the body daily, but any vitamin or mineral taken in megadoses could be potentially dangerous.
Although vets disagree on the importance of supplementing a dogs diet, most dogs remain in good health on a nutritionally complete and balanced dog food and many may benefit from, or at least are not harmed by, certain supplements. For example, consider vitamin C. Unlike people, dogs can synthesize vitamin C in their bodies and may not benefit from a vitamin C supplement the way a person could. Some studies suggest, however, that vitamin C supplements may be useful to highly athletic and working dogs. Dogs who lack the ability to synthesize vitamin C could benefit from supplementation of this antioxidant vitamin. Some breeders believe that vitamin C supplementation helps maintain orthopedic health in giant breeds. When it comes to canine dietary supplements, dog owners and their veterinarians must consider many variables.
The best course of action is to talk to your vet about supplements and determine together if your dog is likely to have a particular deficiency, then supplement that deficiency specifically. Or, if you are interested in supplements to treat a chronic disorder like arthritis or allergies, be sure to tell your vet that you are considering this kind of addition to your dogs health regimen. Your vet may have new information about the safety and efficacy of supplements. For example, the FDA announced that certain substances previously available for dogs such as comfrey and kava kava may not be safe. Because your vet may have access to dog health news you don't hear about, it pays to ask before giving your dog a new supplement.
Until supplements are more closely regulated, follow these safety precautions:
- Look for quality: Buy supplements from reputable manufacturers.
- Follow directions: Always follow package directions for dosage. Don't base an estimate of your dogs doseage on how much of the supplement you take.
- Adhere to animal specifications: Never give your dog a supplement packaged for a human or for a different type of animal. For instance, don't give a cat supplement to a dog, and vice versa. Accurate dosage matters when it comes to small animals.
- Inform your vet: Always tell your vet if you are supplementing your dogs diet.
- Herbs and supplements should be treated like any other medication or dietary change: if your dog experiences any sudden change in health or behavior, see your vet.
