Top 4 Supplements Every Large Dog Should Take
Large breed dogs face unique health challenges because of their size, including joint stress, digestive sensitivities, and higher nutritional needs. The right supplements can make a huge difference — supporting joint health, maintaining a healthy weight, improving digestion, and keeping energy levels high. Supplements can play a vital role in supporting long-term wellness and complementing a high-quality diet. In this post, we’ll cover the top 4 supplements every big dog should have in their routine.
Top-RAted Supplements for large and Giant Breed Dogs
1. Glucosamine & Chondroitin
Large breeds put extra stress on their joints due to their size and weight. Over time, this can lead to wear-and-tear, arthritis, and hip or elbow dysplasia. Glucosamine and chondroitin help protect cartilage, support joint lubrication, and improve mobility. High-quality dog foods often already include joint-supporting nutrients like glucosamine and chondroitin, but adding a supplement can provide an extra layer of support—especially for large breeds during growth phases. Studies in dogs with osteoarthritis have shown that combinations of glucosamine and chondroitin produced statistically significant improvements in pain and joint function.
Tip: Add VetriScience GlycoFlex to promote cartilage health and Nutramax Dasuquin, a clinically proven joint support supplement, to your large dog’s daily feeding routine for extra protection and mobility support.
2. Omega-3 Fatty Acids (Fish Oil)
Omega-3 fatty acids are powerful nutrients that play a vital role in reducing inflammation throughout the body. For large breeds, this means healthier joints, improved flexibility, and reduced stiffness. Omega-3s also contribute to healthier skin and a shinier coat, support cardiovascular health, and strengthen the immune system. In a 90-day veterinary study (JAVMA, Roush et al., 2010*), dogs fed an omega-3–enriched diet showed significant improvements in mobility and weight-bearing compared to those on a regular diet.Long-term use can help large dogs stay active, agile, and vibrant for years.
Tip: Supplements like Zesty Paws Omega-3 Blend or Vital Pet Life Salmon Oil are favorites among dog owners and can help provide joint-supporting, mobility-boosting benefits while also promoting natural allergy relief and inflammation defense.
3. Probiotics
Large breed dogs are often more prone to digestive sensitivities, which can impact nutrient absorption and overall health. Probiotics introduce beneficial bacteria into the gut, improving digestion, reducing digestive upset, and supporting immune function. A healthy gut not only aids nutrient absorption but also contributes to better energy levels, reduced inflammation, and stronger overall health.
Tip: Purina FortiFlora is a top-rated probiotic that supports healthy gut function, making it especially beneficial for large-breed dogs prone to digestive issues and bloat.
4. Multivitamins
Large breed dogs need additional vitamins and minerals to support their size and activity level. Multivitamins help fill nutritional gaps, support bone and muscle health, and strengthen the immune system. They can also improve coat condition, boost energy levels, and promote long-term wellness — especially in older dogs or those with specific health needs.
Tip: Providing comprehensive support from puppy to senior dogs—including joint health, digestion, skin and coat, immunity, and overall vitality—this 8-in-1 multivitamin is an absolute hit with dog owners: Zesty Paws Dog Multivitamin.
Supplements are a key part of maintaining your large dog’s health, supporting joints, digestion, and overall wellness. When combined with proper nutrition and specialized health insurance, they help ensure your big dog stays active, strong, and happy for years.
