Studies generally conclude that the human version of arthritis supplements are not able to be absorbed by dogs. Instead look for a supplement for dogs. The two I recommend our Dasuquan and Duralactin. Starting him on an additional omega-3 fatty acid for dogs will also help with arthritis. Lastly there is a food made by Royal Canin called mobility support. It is excellent for arthritic dogs. I hope this is helpful and please feel free to post any additional questions.

Glucosamine and msm would be the most important ingredients, but essential to fatty acids can also be helpful. I recommend brands that perform quality control like Nutramax Vetri-Science, Phycox and Synovi G4. While joint supplements can be very helpful for arthritis and other orthopedic conditions they probably don’t help prevent intervertebral disc disease that causes back problems in dachshunds.

You want to add glucosamine, chondroitin and msm. These three ingredients together have been clinically proven to provide the most joint support in dogs. These are actuallly either found in a joint food such as prescription brand Hill's J/D or Royal Canin mobility support. You can also find these in joint supplements like Dasuquin (highly recommended) or Cosequin. I hope this helps.

Can my dog take human glucosamine, chondroitin, and MSM supplements?

Yes, as far as we know these supplements are the same. You can use human branded forms of glucosamine, chondroitin, MSM and fish oils for dogs. These supplements are all very safe. Ensure you are using the dose recommended by your vet for maximum efficacy. I hope that helps and Sail gets better soon.

What's the best glucosamine for my dog's arthritis: vet or store?

Thanks for using Petco Pet Education Center, formerly Petcoach! This is a great question! I think the ones that are specifically designed for dogs are way more complete. I would recommend you consider Cosequin or Dasuquin as both cover all the joint supplements such as glucosamine and chondroitin that are great for joint health. Both of these are over the counter. You are usually able to see a marked improvement within weeks to a few months. Best of luck!

What joint supplement for my senior dog with stiff, arthritic joints?

Great question! I really like Dasuquin and Cosequin as joint supplements for dogs. I have found that in senior dogs with arthritis, Dasuquin is a great option because it contains ASU, which stands for Avocado & Soybean Unsaphonifiables. ASU is seen as considerably more effective in regards to repairing stiff, sore, and injured joints. For Oscar, I'd recommend Dasuquin. I hope this helps!

How much human glucosamine for my 25lb dog with joint pain?

There are many different recommended doses for glucosamine/chondroitin, but most veterinarians recommend between 15-30 mg/kg of the chondroitin component as a starting dose. This would be up to 327 mg, so you might want to give just one capsule per day. It should be fine to give with fish oil, although both supplements can potentially cause diarrhea so if you see any diarrhea you may want to ask your veterinarian about decreasing the dose or giving the supplements at different times.

My dog has joint issues. What are the best supplements to try?

Dasuquin with MSM and Cosequin DS Plus MSM (both by Nutramax Labs) are excellent products. I prefer these because it is the same company that makes the human product, Cosamin, and one of the few companies that submits its products for outside testing to verify ingredients. The GlycoFlex line of products would also be one to consider. These are my own personal recommendations.

My dog has arthritis. How can I reduce flare-ups and improve joint health?

When I have patients with arthritis or starting arthritis I always recommend starting a glucosamine supplement. This can be bought over the counter or online. A great animal one is Cosequin. All the directions are on the bottle. This will help lubricate his joints. Thank you for using Petco Pet Education Center, formerly Petcoach.

How much glucosamine should I give my large dog for joint health?

Yes, chicken cartilage can be beneficial, but it must be raw. This can turn off most owners who are hesitant to feed raw foods. Glucosamine may promote joint health and may slow down degenerative joint conditions. It is usually given by weight. Discuss a proper loading dose and maintenance dose with your vet. Glucosamine hydrochloride is preferred over glucosamine sulfate as it is more easily absorbed by dogs. Vitamin C given in junction can also increase absorption. Choose a quality supplement such as Cosequin or Dasuquin.
