Your gentle giant deserves the best care possible.
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 5 supplements every big dog should have in their routine.
Top-RAted Supplements for large and Giant Breed Dogs
1. Glucosamine & Chondroitin
Why it’s important:
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. These nutrients work together to reduce inflammation, ease discomfort, and help maintain your dog’s quality of life as they age.
Recommended Products:
- VetriScience GlycoFlex – promotes cartilage health
- Nutramax Dasuquin – clinically proven for joint support
2. Omega-3 Fatty Acids (Fish Oil)
Why it’s important:
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. Long-term use can help large dogs stay active, agile, and vibrant for years.
Recommended Products:
- Zesty Paws Omega-3 Fish Oil
- Nordic Naturals Omega-3 Dog
3. Probiotics
Why it’s important:
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.
Recommended Products:
- Purina FortiFlora
- Nutramax Proviable
4. Multivitamins
Why it’s important:
Even with a high-quality diet, large breed dogs sometimes 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.

- PetHonesty 10-for-1 Multivitamin
- VetriScience Canine Plus Multivitamin
5. Hip & Joint-Specific Chews
Why it’s important:
Hip and joint chews provide a convenient, tasty way to deliver important joint-support nutrients consistently. They are especially helpful for large breeds, as they combine glucosamine, chondroitin, and other supportive compounds in one treat. Regular use can reduce stiffness, improve mobility, and give your dog the confidence to remain active and playful throughout life.
Recommended Products:
- Doggie Dailies Glucosamine Chews
- Cosequin DS Chewable
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.
