We all want as many years with our Weimaraners as possible. As your Weimaraner ages, you may be looking for additional ways to support their health.
The following list of supplements is among the top recommended products for senior Weimaraners. As always, be sure to consult your own veterinarian before making any changes to your Weimaraner’s dietary or medical regimen.
1. Glucosamine & Chondroitin for Supporting Your Senior Weimaraner’s Aging Joints
Joint pain and arthritis are some of the most common ailments an aging Weimaraner will face. Supplements containing glucosamine aid in replacing 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 Weimaraner
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.
We’d recommend looking into a 3-in-1 probiotic that also contains prebiotics and digestive enzymes.
3. Omega-3 Essential Fatty Acids to Fight Inflammation & Reduce Itchy Skin for Your Senior Weimaraner
Older dogs may experience dry, itchy skin and dull, brittle coats. Adding Omega-3 and Omega-6 fatty acids to a senior dog’s diet can reduce inflammation and promote healthy skin and a soft, shiny coat. Omega-3 fatty acids also support healthy mobility and bone health. Additional benefits in the body include allergy support, heart health, strong brain function, and visual acuity.
Krill oil is one of the best sources of Omega-3 available, as it contains a special form of fatty acids that are more usable in your dog’s body. Additionally, many high-quality krill supplements contain a powerful compound called astaxanthin, a highly potent antioxidant.
4. Milk Thistle for Your Weimaraner’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 Weimaraners, 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 Weimaraners. 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 in 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 Weimaraner’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 Weimaraner’s Digestive Health
Senior dogs may experience changes in the lining of the intestines, which lowers 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 Weimaraner Aging Support
As your Weimaraner’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 Weimaraner 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 Weimaraner.
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 Weimaraners 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.
FAQs About the Best Supplements for Senior Weimaraners
1. What supplements are most important for a senior Weimaraner?
The most important supplements for senior Weimaraners usually include joint support (glucosamine, chondroitin, MSM), omega-3 fatty acids, probiotics, and antioxidants to support mobility, digestion, and overall aging health.
2. Do senior Weimaraners need joint supplements?
Yes. Because Weimaraners are large and active dogs, they are prone to hip dysplasia and arthritis as they age. Joint supplements with glucosamine, chondroitin, MSM, and green-lipped mussel help maintain cartilage and reduce stiffness.
3. Are omega-3 fatty acids good for older Weimaraners?
Absolutely. Fish oil and krill oil supplements rich in omega-3s (EPA & DHA) support heart health, brain function, and reduce inflammation in joints.
4. Should I give my senior Weimaraner probiotics?
Yes. Senior dogs often develop digestive issues, and probiotics with prebiotics can help balance gut bacteria, improve nutrient absorption, and support immune function.
5. Do Weimaraners benefit from antioxidant supplements?
They do. Antioxidants like vitamin C, vitamin E, and CoQ10 help fight free radicals, support cellular health, and may slow down cognitive decline in older Weimaraners.
6. What supplements help with cognitive health in senior Weimaraners?
Supplements containing DHA (from fish oil), phosphatidylserine, and antioxidants can support brain health and reduce symptoms of canine cognitive dysfunction (doggy dementia).
7. Can senior Weimaraners take multivitamins?
Yes, but choose senior-specific multivitamins to ensure they’re getting the right balance of vitamins and minerals without over-supplementing.
8. Do senior Weimaraners need immune support supplements?
Yes. Mushroom blends, probiotics, omega-3s, and vitamins A, C, and E can strengthen immune defenses, helping senior Weimaraners fight infections.
9. Are hip and joint chews good for Weimaraners?
They are an excellent choice. Soft chews with glucosamine, chondroitin, MSM, turmeric, or green-lipped mussel are both tasty and beneficial for senior dogs with joint issues.
10. Should I give my Weimaraner supplements for heart health?
Yes. Taurine, L-carnitine, and CoQ10 support cardiac function, which is important because Weimaraners can be prone to heart conditions as they age.
11. Are skin and coat supplements necessary for older Weimaraners?
They can be very helpful. Omega-3s, biotin, and zinc improve skin hydration, reduce shedding, and keep their coat shiny and healthy.
12. What natural supplements can help senior Weimaraners?
Natural options like turmeric (for inflammation), green-lipped mussel (for joints), and bone broth powder (for digestion and joint lubrication) can be excellent additions.
13. Can I give my Weimaraner human supplements?
Not recommended. Many human supplements contain unsafe levels of ingredients for dogs. Always use dog-formulated supplements specifically designed for their size and needs.
14. How do I choose the best supplements for my senior Weimaraner?
Look for supplements that are vet-approved, third-party tested, and made with natural, high-quality ingredients. Always tailor choices to your dog’s health needs.
15. Should I consult a vet before giving supplements to my senior Weimaraner?
Yes. Every senior dog has unique needs. A vet can recommend the right dosages and supplement combinations to avoid interactions with medications.
