What is Extend Joint Care™?

Extend Joint Care™ for Dogs combines four active ingredients in a single non-prescription dietary supplement designed to improve and maintain joint health in your dog. Our unique blend consists of Glucosamine HCL, MSM (Methyl Sulfonyl Methane), Type II Chicken Collagen, and Ascorbic Acid. Each ingredient plays a vital role in supporting hip and joint health in your Dog. At Extend Pet Health, we have formulated this product to be one of the safest and most effective joint care supplements for your dog, supporting healthy joints.

How does it work?

Extend Joint Care™ is the simple way to help ensure that your dog's joints stay healthy and strong through the course of their whole lives. Four active ingredients work synergistically to support joint health, increase joint strength and viscosity, and protect joint cartilage from damage and wear. For additional details, read up on how it works.

Are there any studies on any of the ingredients in Extend Joint Care™?

In what kinds of cases is Extend Joint Care™ most beneficial?

Extend Joint Care™ is most effective for dogs with existing symptoms of joint problems. It also has preventative uses, reducing or eliminating the need for joint injections or other procedures that may have unpleasant side effects.

Is Extend Joint Care™ safe?

Extend Joint Care™ is not known to have any side effects or contraindications. Glucosamine has previously been associated with gastrointestinal upset and increased urination in some dogs. In this event, glucosamine should no longer be administered. Extend Joint Care™ is not intended for use in other animals. Feel free to ask your Vet! We have not yet heard of a vet who has did not recommend it after seeing the ingredients!

FULL PRECAUTION: Safe use in pregnant animals intended for breeding has not been proven. Consult with your veterinarian before using this product in animals with clotting disorders, being treated with anticoagulant medications, diabetes, or any metabolic disorder causing hyperglycemia, history of urinary tract stones, or known allergies to shellfish. Federal law prohibits the extra label use of this product in ruminants. If lameness worsens or persists, discontinue use and contact your veterinarian.

Is Extend Joint Care™ expensive?

Extend Joint Care™ is priced competitively with other leading supplements. However, with its high concentration of quality ingredients, you will find that it carries the load of many other supplements combined. Not only that, but you only need to give one dose per day, nothing more. These benefits combined mean you save money and your dog lives happier and healthier. Just read through our long list of testimonials.

My veterinarian doesn’t know what Extend Joint Care™ is. What can I do?

We're not surprised, as our company is small, though growing fast! If your veterinarian is not familiar with Extend Joint Care™, please have them email questions to

Is Extend Joint Care™ safe to use combined with other supplements or pharmaceuticals?

Extend Joint Care™ is a natural supplement with no known negative interactions. While we’re confident in its ability to improve joint health in your dog, it is not a "miracle cure." Your dog may still need other supplements or prescriptions. Dogs taking NSAID (such as Rimadyl, Prevacox, Deramaxx, and others) may see positive effects of Extend Joint Care™ and can reduce their dosages accordingly. Dogs also have no need to take other, similar supplements alongside Extend Joint Care™. Consult with your veterinarian to formulate the optimum solution for your dog's health.

Is a loading dose necessary?

No, a loading dose is not necessary when administering Extend Joint Care™. But feel free to begin with 1/2 packets for a couple days to see how your dog takes to it.

Should I change dosage depending on the size of my dog?

One packet per day should suffice for most dog sizes. However, you know your dog better than we do, so you can decide if your Teacup Maltese may need less or your Neapolitan Mastiff may need more.

When can I expect to see results from my dog taking Extend Joint Care™?

Extend Joint Care™ goes to work at the cellular level right away, though it may take a short period of time for the effects to manifest themselves. While many happy customers have seen dramatic results in a few short days, know that every dog is different. We recommend waiting two weeks before expecting any visible results.

Could my dog be allergic to something in Extend Joint Care™?

Check the ingredient list carefully and consult with your veterinarian before administering Extend Joint Care™ if your dog has a known allergy. One fact to keep in mind is that the Glucosamine used in the Extend Joint Care™ Hip and Joint formulas is extracted from the horny chitin of shellfish and crustaceans. Contact your veterinarian immediately if your dog develops a reaction to any product.

Yes. We offer a 30-day 100% money back guarantee for our Extend Joint Care™ if you are not completely satisfied.
