You know your dog best in terms of personality and dietary preferences, but how much do you really know about what’s going on inside your dog’s body?

Your dog requires a delicate balance of essential nutrients to enjoy optimal health and long-term well-being. Most of the nutrients he needs can (and should) be obtained from your dog’s diet but some dogs need a little extra help.

If your dog is a picky eater or suffers from health problems that impair his ability to absorb nutrients, a multivitamin might be a good addition to his daily routine. Other dogs can benefit from supplementation of a specific nutrient or the addition of active ingredients to provide support for various issues like joint pain, skin problems, or digestive issues.

We’ve done the research to determine some of the best dog supplements in various categories to help you decide which option is right for your dog.

Before we get into the details of our recommendations, let’s take a closer look at the subject of vitamins for dogs and whether dogs really need daily supplements.

Does Your Dog Need Supplements?

According to the Centers for Disease Control and Prevention (CDC), over 57% of American adults over the age of 20 take a daily supplement. It’s completely natural for pet owners who are proactive about their own health to want to take the same steps for their dog, but is it necessary?

The biggest determining factor in your dog’s long-term health and wellness is the quality of his nutrition. Most commercial dog food recipes are formulated to provide for the basic requirements of dogs, but certain challenges can stand in the way of your dog receiving a balanced diet.

Picky eaters may prefer supplemental foods or treats over a nutritionally balanced dog food.

Dogs with dental health issues may have a hard time eating.

Underlying health problems may interfere with a dog’s ability to properly absorb nutrition.

These are examples of cases in which a veterinarian might recommend daily supplements to make sure a dog gets the proper daily dose of essential vitamins and minerals.

In most cases, however, supplements are not necessary. In fact, taking supplements when it isn’t required could have a detrimental effect on your dog’s overall health.

If your dog already gets the nutrients he needs from a balanced diet, supplements could result in an excess of certain nutrients. Excess calcium in the diet can lead to skeletal malformations in puppies, especially when it isn’t properly balanced with phosphorus. Too much vitamin A could exacerbate joint pain and harm the blood vessels while excessive vitamin D can cause bone and muscle problems.

Before giving your dog any kind of supplement (especially human vitamins or supplements), it’s important to consult your veterinarian. Your vet can confirm your dog’s need for a supplement and tell you what nutrients he needs and in what dosage.

How To Choose The Right Dog Supplement

If your veterinarian recommends a supplement for your dog, he may have a specific brand he suggests based on your dog’s individual needs. If not, there are a few things you should look for when shopping around for supplements.

  1. Choose A Supplement Made With Scientifically Supported Ingredients.

If your dog suffers from joint pain, an all-in-one multivitamin may not be necessary. It’s best to choose a supplement formulated for the specific issue your dog is having and look for scientifically supported active ingredients.

More than just the ingredients listed, however, it’s a good idea to check for a certification from the National Animal Supplement Council (NASC). This organization sets labeling guidelines and tests products to see if the formulation matches the claims on the label.

  1. Check For Clinical Studies And Quality Control Measures.

Not only do you need to make sure that the list of ingredients includes the things your dog needs, but you want to verify that the product actually contains those ingredients. Many brands have begun to place QR codes on their labels which enable you to look up the exact lot number for the product and view safety information and independent lab results.

For supplements designed to support a specific area of your dog’s health, it’s a good idea to choose a company that has commissioned clinical studies on their products. If you can’t find information on the website, look for a contact number for the company and call to ask.

  1. Look Out For Unnecessary Ingredients.

Once you’ve verified that the supplement contains the right active ingredients, make sure there isn’t too much else on the list. Avoid products that are overly loaded with carbohydrates and formulas that contain artificial additives like artificial flavoring, coloring, and preservatives.

If your dog has food allergies or sensitivities, it’s particularly important to pay attention to the list of ingredients. Many supplements include animal proteins for natural flavor.

  1. Take Marketing Claims With A Grain Of Salt.

While the NASC sets certain requirements for labeling and makes some effort to verify claims, it’s your job as a consumer to be responsible when selecting products. Be wary of claims on the label that sound too good to be true or that speak in generalities rather than specifics.

Keep in mind as well that dog vitamins and supplements aren’t a cure-all. They’re designed to help support your dog’s health and wellness in the areas where support is needed.

Now that you have a better understanding of when your dog might benefit from a supplement and how to choose one, let’s get into our top picks.

Final Thoughts

Not all dogs require a daily supplement. The best vitamins and supplements for your dog are ones your veterinarian recommends based on your dog’s nutritional needs and health status.

If your vet determines that your dog could benefit from a daily supplement, be sure to ask which specific ingredients to look for and what dosage. Keep in mind with vitamin supplements that the majority of your dog’s daily value will come from his staple diet – a supplement is only designed to boost his intake to the appropriate level.

In addition to be mindful of the active ingredients and dosages in your dog’s supplements, look for a recipe made with high-quality ingredients that is formulated by a licensed veterinarian.
