Pet supplements have become a billion-dollar industry, but do dogs really need them? Are they safe? Undoubtedly, supplements are not created equal, some work, others don’t, and many are not necessary and may even prove to be harmful to dogs.

If you are giving your dog a complete and balanced diet (premium quality), he probably will not require any supplements, particularly if he is active and healthy. But if your dog is on a homemade diet, supplements may be necessary to ensure that your pet does not suffer from specific deficiencies and their associated ill effects. It is recommended that you check with your veterinarian or pet nutritionist to determine what supplements your pet may require.

Do dog supplements work?

Certain supplements may be recommended by your veterinarian if your dog is found to be suffering from certain health issues that warrant the need for supplementation. However, your dog should undergo a thorough checkup before it can be ascertained if he will benefit from supplements or not.

How effective a supplement can be will depend to a large extent on how it is manufactured and the quality of its ingredients. Many commercially available dog supplements have not gone through clinical trials. Your best bet is to go for supplements from reputable companies but do make sure to do your homework and try to learn as much as you can about the supplement that has been recommended by your vet.

Risks of giving supplements to dogs

According to the FDA and many veterinarians, dogs that are already on a premium quality diet do not need supplements because it could have harmful consequences. Excess amounts of certain vitamins and minerals in the body can lead to serious problems. Some of the common examples are:

  • Too much calcium can pave the way for skeletal problems particularly in large breed of puppies
  • Excess vitamin A can increase a dog’s risk of dehydration and pain in the joints. There is also a negative effect on blood vessels.
  • Too much vitamin D can cause muscle atrophy, bone problems, and loss of appetite.
  • Herbal supplements, even if they are using natural ingredients, can also have potential side effects and/or cause negative reactions.

If your dog is suffering from a certain health issue, like arthritis or liver disease, you should never attempt to forego traditional treatment methods and give supplements and herbals instead. There are ingredients in some supplements that may interact negatively with a medication that your dog may be taking.
