What Are Dog Supplements and How Do They Work?

The market for dog supplements has increased exponentially over the past several years as pet parents strive to do everything they can to ensure their pets have happy, healthy lives. While many dogs on an AAFCO-approved diet may not need supplements, those with medical conditions or predispositions to certain diseases can benefit significantly from them.

It’s crucial to discuss supplement recommendations with your veterinarian before adding any to your dog’s diet. Your vet can help you find a product that fits your dog’s specific health needs.

What Are Dog Supplements?

Dog supplements are products added to a pet’s regular diet that contain ingredients intended to improve health. The National Animal Supplement Council (NASC) is a nonprofit industry group that awards a seal to manufacturers who meet the council’s standards for safe, effective, and high-quality products. When searching for a supplement, look for the NASC seal to ensure it has met these standards.

Scientific research has studied many common ingredients in supplements, and your veterinarian is the best resource to help you determine which products may be beneficial for your dog’s health conditions. While none are magic bullets, many supplements may help slow disease progression or support your dog’s body to prevent illness.

Why Do Veterinarians Recommend Supplements?

Veterinarians often recommend supplements to enhance other prescribed therapies or potentially prevent health issues, such as arthritis, from progressing. For instance, dogs with heart disease or those at risk of developing it may benefit from fatty acid supplements.

While a well-balanced diet is the cornerstone of nutrition, supplements can help augment the nutrients available. Some homemade diets, which are not reviewed or balanced by a veterinarian or nutritionist, often need added supplements to ensure the correct vitamin and mineral ratios are met. In such cases, a veterinarian or veterinary nutritionist should ensure the dog’s diet is complete.

How Supplements Work for Dogs

Supplements work by adding nutrients to the diet. For some dogs, having more nutrients available can help reduce or prevent certain illnesses. Puppies have different requirements than adult dogs due to their growing bodies, and senior dogs often have health conditions that supplements can help treat.

Common Ingredients in Dog Supplements

Glucosamine and Chondroitin

Glucosamine and chondroitin are common ingredients in many joint supplements and make up a compound typically found in cartilage. Supplements with these ingredients can help joint cartilage stay healthy or heal and support the fluid lubricating the joints. Glucosamine and chondroitin may be recommended for dogs with hip dysplasia, osteoarthritis, cartilage damage, or loose joints.

Keep in mind that glucosamine must be used long-term to see any beneficial effects and won’t treat the pain of arthritis or joint issues in dogs. Work with your veterinarian to determine the best inclusion of both a joint supplement and pain medication, if needed, depending on your dog’s health.

Antioxidant Supplements

Antioxidants are substances that protect cells from free radicals, molecules that circulate in the body. Antioxidants can reduce inflammation, prevent disease, and help support the body during natural aging.

Fish Oil Supplements

Fish oils are omega-3 fatty acids, antioxidants that can improve coat and skin health, support the muscles of the heart, and help with brain development.

Probiotic Supplements

Probiotics are microorganisms that are beneficial to a body’s normal health processes. Probiotics help rebalance the flora in the gastrointestinal tract to help heal after illness or to maintain good flora levels in pets predisposed to disease-causing chronic diarrhea or inability to absorb nutrients. Many times, probiotics are used during or after antibiotic therapy to replace some of the “good” organisms that can be collateral damage with antibiotic use.

Liver Supplements

S-adenosylmethionine (SAM-e) is a common liver support supplement that mimics glutathione, a compound made by the body that is used to detoxify and protect the liver. Liver supplements are often recommended for toxin ingestion, gallbladder disease, or hepatitis.

Real-World Perspective

Case Study: Max’s Joint Health Journey

Max, a 7-year-old Labrador Retriever, started showing signs of stiffness and discomfort in his hind legs. His owner, Jane, took him to the vet, where he was diagnosed with early-stage arthritis. The vet recommended a combination of glucosamine and chondroitin supplements along with prescribed pain medication. Over a few months, Jane noticed Max's mobility improved, and he seemed more comfortable during their daily walks. This experience highlighted the importance of supplements in managing chronic conditions and enhancing the quality of life for dogs like Max.
