The Power Duo for increased joint needs.
This set combines our premium products for targeted support during heavy strain. Ideal for accompanying challenges such as joint wear, instability of the kneecap (patella), as well as issues with hips and elbows.
Suitable for dogs from 12 months. (For younger and stomach-sensitive dogs, we recommend JOINTS elements or JOINTS greenshell.)

The products supplement your dog's daily feeding with valuable micronutrients. They contribute to accompanying the normal function of the joints and supporting physiological mobility, even with heavy strain or breed-specific issues.
The certified feed supplements supply the organism with valuable micronutrients in an optimally usable dose. The synergy of JOINTS (with glucosamine, collagen, MSM, devil's claw, and frankincense) and JOINTS greenshell (with green-lipped mussel, collagen, vitamin E, and B vitamins) supports elastic and resilient cartilage tissue. Furthermore, fascia, ligaments, and tendons, which are important for the stability of the joints and kneecap, are strengthened nutritionally.
Supporting the physiological production of joint fluid (synovial fluid) ensures better lubrication. Additionally included B vitamins can accompany the regeneration of nerve pathways, which are often affected by joint instabilities. The goal is to maintain the joy of movement in a natural way.
Through the division into weight classes small, medium and large, you can feed your dog exactly the right dose needed for ideal utilization.

Issues such as malformations in the hip (HD) and elbow (ED) or age-related joint wear (osteoarthritis) place high demands on the nutrient supply. When cartilage tissue is stressed, a targeted supply of joint nutrients is essential. The JOINTS combination provides exactly these building blocks to nutritionally accompany normal function and regeneration.
A dislocated kneecap (medically called patellar luxation) occurs often in smaller, but also in large dogs. It ranges from slight instability to permanent problems. In addition to mechanical stress, surrounding nerves and ligaments can also be affected.
Our expert advice: With a high degree of severity, surgery is often necessary, but should always be carefully considered. Whether a conservative path with physiotherapy is an option is best discussed with your veterinary practice. Strengthening the surrounding tissue (ligaments, fascia, muscles) is crucial to better fix the kneecap. Our nutrient combination can make a valuable contribution here.
During the heat cycle, ligaments can become more “stretchable” due to hormones. This is a natural process but can influence stability in predisposed dogs. We recommend focusing on strengthening the tissue through physiotherapy and high-quality feed supplements.
JOINTS greenshell also contains B vitamins and the antioxidant vitamin E. B vitamins are important for smooth nerve function, as nerve pathways can be irritated by joint instabilities. Vitamin E acts as a radical scavenger and supports cells as well as the immune system.

Great support
Great product. My dog has significantly fewer—if any—joint problems now.

in cases of a large patella
It was a shot in the dark, after I’d already tried a few things. My dog has a Grade 3 (maybe even a little worse), and sometimes the patella needs to be guided back into place with some help. Surgery is only an option for me in an absolute emergency—that is, when it’s really stuck. Sandra’s consultation was excellent and honest—he also said that, given the severity of the dislocation, it was worth a try. Now, after two months, the patella doesn’t pop out as often, and—most importantly to me—it slips back into place on its own. This is a huge success, because up until now, every vet wanted to operate right away! I’m definitely going to keep at it and hope it stays this way.

A Great Combination with a Big Impact
We were diagnosed with a Grade 1–2 patella condition. Any surgery is a major ordeal for an animal, and I wanted to avoid that. While doing my research, I came across dogfit and decided to try the combination—partly because of all the great reviews. Kjell now gets it every day, and we also do muscle training for his hind legs every other day. I’m very satisfied and plan to stick with it! Kjell and I highly recommend it!

Grade 2 to 3 patellar injuries in both knees...
Grade 2 to 3 patellar luxation in both hind legs. Two vets, one veterinary clinic, three opinions. We looked into alternatives. Four months have passed since then, and we were able to avoid surgery!! Let’s hope it stays that way. Thank you!

Very satisfied
My little Chihuahua started hopping and walking on three legs. According to the (exorbitantly expensive) veterinary clinic, it was a patellar luxation and she needed surgery. On the recommendation of my animal naturopath, I tried this combination product. After about two months, I noticed that she was hopping much less often overall than before. I highly recommend it!

After removing the contents, it is recommended to soften the capsule in a little water and add it as well.
Please store in a dry, cool place (6-25 °C), protected from light and out of the reach of small children.

The two supplements work at different points and therefore complement each other well in daily feeding: JOINTS greenshell and JOINTS can be given in one step instead of ordering two products separately. The set is also cheaper than buying individually. You will find what each supplement contains under “Ingredients”.
Both work. As a rule, JOINTS greenshell and JOINTS can be fed together or split between morning and evening. All that matters is that your dog receives each of the two once a day. Choose whatever fits your daily routine.
JOINTS greenshell & JOINTS is generally very well tolerated. We select our ingredients for high quality and a natural composition. As with any natural product, an individual dog may still react sensitively to a single ingredient. If you notice signs of intolerance, pause the supplement and get in touch with us. We are happy to help. If your dog has pre-existing conditions or receives a special diet or medication, please also talk to your veterinary practice.
Give JOINTS greenshell & JOINTS regularly for at least six weeks, in some cases longer. How quickly you notice something varies from dog to dog and depends on your dog's individual needs. Natural formulations need time to unfold their supporting properties: regular feeding matters more than a high single dose.
The set contains two packs of 60 capsules each. Feeding both supplements daily, it lasts around two months. If your dog receives an extra capsule according to the dosage recommendation, it will last correspondingly less.
That can almost always be solved. Many dogs accept the capsule more readily when it is embedded in something soft: a spoonful of wet food, quark or a piece of liver sausage usually does the trick. If your dog doesn't like the capsule at all, you can also open it and mix the contents into the food. One note on this: with JOINTS greenshell and JOINTS the capsule shell is made of high-quality beef gelatine and is therefore a valuable component in itself. So don't throw it away after opening. Soften it briefly in a little water and add it to the food. What matters most is regularity: an occasionally missed dose is no problem, but feeding should not be interrupted for long.
