As Australian Shepherds enter their senior years, they can benefit from targeted nutritional support to help maintain their energy, mobility, and overall health. The best supplements for a senior Australian Shepherd can promote healthy joints, brain function, digestion, immune health, and more, helping your dog stay active and comfortable. This guide highlights top supplement choices to help you find the right option for your aging Aussie and support a happy, healthy life.
Best Senior Australian Shepherd Supplements
1. Glucosamine & Chondroitin for Supporting Your Senior Australian Shepherd’s Aging Joints
Joint pain and arthritis are some of the most common ailments an aging Australian Shepherd will face. Supplements containing glucosamine help replace lost joint fluid, providing much-needed lubrication and cushioning to stiff, achy joints. Chondroitin sulfate has been shown to improve the structural integrity of joints by repairing damaged cartilage and preventing further cartilage breakdown.

2. Probiotics for Immune & Gut Support for Your Senior Australian Shepherd
Probiotics are supplements containing large doses of microorganisms. They promote a healthy GI tract by allowing the “good” bacteria in the gut to flourish. “Bad” bacteria often accumulate due to stress, illness, and prolonged use of medications. Since the majority of your senior dog’s immune system is located in the gut, probiotics also help to maintain health throughout the body.
iHeartDogs Pupkin™ Probiotics, Prebiotics, & Postbiotics is a complete daily digestive supplement designed to support healthy digestion, firmer stools, and immune function. It combines 3 billion CFU of probiotics across four beneficial strains with prebiotics and postbiotics to help nourish beneficial gut bacteria and maintain a healthy intestinal environment. Pumpkin provides a natural source of fiber to help regulate bowel movements, while digestive enzymes promote better nutrient absorption. The formula also includes bone broth to help support the digestive tract and turkey tail mushrooms for additional immune support, making it an excellent daily choice for dogs with sensitive stomachs or aging digestive systems.
3. Honey Guard™ – Allergy & Itch Omega 3-6-9 Powder
As Australian Shepherd dogs grow older, maintaining healthy skin and a soft, shiny coat can become an important part of their overall wellness routine. Honey Guard™ Allergy & Itch Omega 3-6-9 Powder is a great option for senior Australian Shepherds because it provides a blend of Omega 3, 6, and 9 fatty acids, including pure Antarctic krill oil, to support healthy skin and coat condition. It also helps maintain normal skin moisture and provides nutritional support for dogs that experience seasonal or environmental allergies. The convenient powder formula mixes easily into food, making it especially useful for senior dogs that may be picky eaters or have difficulty chewing supplements.
This supplement fits well into a daily health plan for an aging Australian Shepherd by offering targeted skin and coat support alongside a balanced diet and regular veterinary care. Every purchase also helps feed shelter dogs, making it a choice that benefits dogs beyond your own companion. If skin and coat health are a priority for your senior Australian Shepherd, Honey Guard™ Allergy & Itch Omega 3-6-9 Powder is worth checking out.
4. Milk Thistle for Your Australian Shepherd’s Liver & Kidney Support, Especially for Dogs Taking Pain Meds
Natural milk thistle is said to protect the liver from damage and may actually improve liver function. This is important for aging Australian Shepherds, especially those with existing liver problems and those taking medications known to be taxing on the liver. For example, any dog regularly taking an NSAID pain medication such as carprofen, Novox, Rimadyl, deracoxi, Deramaxx, firocoxib, Previcox, meloxicam, Metacam, grapipant, or Galliprant may need additional liver support. Make sure to discuss this with your vet.
5. Curcumin (from Turmeric) for Pain & Inflammation
This “wonder spice” is a derivative of turmeric and promotes brain and joint health in aging Australian Shepherds. Some studies have suggested that turmeric can provide nearly the same pain relief as an NSAID drug. Lastly, curcumin is also known for its possible anti-tumor properties and for helping to support dental health.
Many high-quality hip and joint supplements, such as this one, contain turmeric in the formula.
6. Hemp Oil for Your Senior Australian Shepherd’s Pain & Inflammation
No discussion of senior dog supplements would be complete without discussing hemp. In the last 5 years, several studies have begun to show great promise for hemp in helping to alleviate joint pain, calm nervous dogs, reduce inflammation caused by allergies, and reduce seizures in epileptic pups.
We’d recommend a hemp oil or hemp chew that contains 0% THC, as well as using a product that is tested multiple times throughout the manufacturing process to ensure a pure and potent product. Here at iHeartDogs, we only sell and recommend the Cannanine brand.
7. Fiber for Your Senior Australian Shepherd’s Digestive Health
Senior dogs may experience changes in the lining of the intestines, which lower their ability to digest and absorb the nutrients in their food. Adding healthy fiber to your older pup’s diet supports a healthy digestive system, combats constipation, and promotes overall health.
8. Extra Protein for General Australian Shepherd Aging Support
As your Australian Shepherd’s body ages, it breaks down muscle and tissues at a faster rate than before. For this reason, aging dogs need extra protein in their diet (note: there are some exceptions, such as if your senior dog has chronic kidney disease, in which your vet may recommend a lower protein diet).
Many senior Australian Shepherd parents opt to add additional protein to their dog’s kibble, such as a cooked or raw egg, chicken breast, or a freeze-dried dog food topper. Surprisingly, most kibbles only contain around 20-30% protein, so boosting this vital nutrient can be very helpful for seniors. It can also substantially help their appetite!
9. Dog-Safe Mushrooms such as Shiitake, Turkey Tail, & Reishi for Immune Boosting Support
Mushrooms are an incredibly exciting area of emerging nutritional studies. Some clinical trials have shown great promise in extending the lifespan of dogs battling cancer. And while it’s not a miracle, mushrooms like Reishi, Turkey Tail, and Shiitake can undoubtedly boost the immune system of your Australian Shepherd.
As you are probably aware, many mushrooms can be toxic to dogs, especially those found in your yard. Make sure to use a dog-safe mushroom supplement if you choose to give one to Fido. This particular formula contains 6 different mushrooms, as well as organic chicken bone broth.
10. Collagen-rich bone Broth, which supports healthy joints and skin in seniors
One of the biggest causes of early death in Australian Shepherds is reduced mobility. Bone broth is packed with joint-supporting nutrients like glucosamine, chondroitin, and collagen, all of which help keep your older pup mobile longer. In addition, most senior dogs LOVE the flavor, and it will boost the nutrition and taste of their current food.
The product iHeartDogs recommends and sells contains both bone broth and 6 different immune-supporting mushrooms.
