We all want as many years as possible with our old English Sheepdogs. As your old English Sheepdog 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 old English Sheepdogs. As always, be sure to consult your own veterinarian before making any changes to your old English Sheepdog’s dietary or medical regimen.

1. Glucosamine & Chondroitin for Supporting Your Senior Old English Sheepdog’s Aging Joints

Joint pain and arthritis are some of the most common ailments an aging Old English Sheepdog 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 Old English Sheepdog

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 Old English Sheepdog

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. In addition, many high-quality krill supplements also contain a powerful compound called astaxanthin, a highly potent antioxidant.

4. Milk Thistle for Your Old English Sheepdog’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 old English Sheepdogs, 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 old English Sheepdogs. 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 Old English Sheepdog’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 Old English Sheepdog’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 Old English Sheepdog Aging Support

As your old English Sheepdog’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 English Sheepdog 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 old English Sheepdog.

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 Old English Sheepdogs 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.
