JOINTS Joint Complex for Dogs

DOG FIT DogJOINTS is a high-quality supplement for dogs, developed for the daily support of normal joint function and mobility. Our carefully balanced formula combines proven knowledge from animal health and combines proven ingredients with modern nutritional findings. Thanks to the combination of selected ingredients, JOINTS is particularly suitable for dogs whose musculoskeletal system, i.e., joints, cartilage, ligaments, tendons, vertebrae, and kneecaps, is particularly stressed in everyday life.

Our formula combines glucosamine, collagen, MSM, and extracts of frankincense and devil's claw. These are traditionally used to support joints and the musculoskeletal system.

Tip: JOINTS is also available in a combo set with VITAMIN B or JOINTS greenshell, cheaper than the two individual products at the regular price.

Very good!

We have a French Bulldog with disc and spinal problems. Ever since Rudi started getting the combination of Joints and Vitamin B, he’s been more mobile and better balanced. A big thank you also to the customer service team—they’re always friendly and helpful! ❤️❤️

Thank you!

Our Louie has been taking the pills for almost 3 months now, and I get the impression that he’s doing really well. He really enjoyed the summer; he’s rolling around in the meadow again and lying relaxed on his back—something he didn’t used to do.

Our feedback: Dear Julia, our entire team is so happy that we were able to help Louie. That’s exactly why we do what we do! We wish Louie—and of course you, too—many more wonderful summers! Best regards, Sandra

Works wonders for Grade 1 patellar dislocation

My foster dog (an Akita) is missing a front paw. Due to her gait abnormality and the lack of a brace in Romania, her patella kept popping out at first. Thanks to the capsules, I felt after a short time that things were improving, and after two months, I get the impression she’s managing better.

Just a simple thank you.....

Wow, what can I say... I don't usually write reviews, but this product has won me over 100 percent! I adopted my little Pinschi (3 years old) half a year ago, and the previous owner warned me that if he steps on something, he’ll start howling loudly out of shock! When it happened for the first time, I was glad I’d been warned! I didn’t ignore it for long because it didn’t seem normal to me, and he really did howl loudly for a whole minute in pain! The vet diagnosed a patella (knee) issue, but thank goodness he’s not the type who’s just out to make money—so he told me there are ways to avoid surgery and that I should try this first… No sooner said than done—I searched online and discovered this site! And after three weeks, he only whimpered a little when I applied the treatment—and that was it! Now the package is almost empty, and what can I say… when he “stretches” now, his leg tenses up for a few seconds, and that’s it! No more pain....I thank YOU from the bottom of my heart! You can’t even imagine how wonderful it is to go for a walk without worrying that the dog might cry out in pain and you’d have to watch helplessly ❤️

Recommended

After a period during which our 11-year-old male dog would only defecate while walking and no longer sat down to do so, we took him to our veterinarian, who told us he had an anal gland infection. Antibiotics and painkillers were effective against the inflammation, but there was no change in his defecation. The vet recommended an X-ray under light sedation, which I refused because he hadn’t handled surgery well a few years ago. I observed and palpated my dog more closely than usual and figured out the likely cause: pain in his left hip. The vet said the only option was painkillers and anti-inflammatories, but that was out of the question for me. Treating the symptoms doesn’t address the cause. Osteoarthritis was very likely. After a few hours on the computer, I came across this site—I figured I’d give it a try—though, to be honest, I thought it would be a waste of money. We started giving him the capsules—one a day—and after 3 days he was walking better; after 1 1/2 weeks, he was holding his tail up again during walks; and after just under 3 weeks, he’s now defecating normally again. He’s back to his usual self. We can go on longer walks again, he’s playing with his friends again, and he doesn’t make any sounds of pain at all. Looking back now, it was the best decision I could have made. He’s doing very well, and I thank everyone for bringing his zest for life back.

Highly recommended

Our dog has arthritis in his hind legs. The physical therapist at the veterinary clinic recommended Joints to us. He still has a little trouble getting up in the morning, but overall he’s almost back to his old self. It works really well—full marks!!

Very satisfied

My dog was diagnosed with Grade 1 patellar luxation, and the vet wanted to perform surgery. The animal welfare organization recommended that I seek a consultation with you. The consultation was very thorough—thank you so much. That alone is worth a few stars. I’m giving you full stars because my dog is doing much better after 2 months! The patella only pops out rarely now—maybe once every two weeks—and I can tell by the way he walks. Awesome!!!!

Questions

Which dogs is JOINTS intended for?

For adult dogs of any size and breed. We especially have in mind dogs whose musculoskeletal system is under greater everyday load: active and sporting dogs, as well as large and heavy breeds. For dogs from about 7 years of age we recommend CARE senior. JOINTS is a complementary feed for daily feeding and no substitute for a balanced diet. If your bitch is pregnant or nursing, or your dog is currently under veterinary treatment, please discuss supplementary feeding with your veterinary practice first. You will find the right size for your dog's weight under “Dosage instructions”.

Is JOINTS well tolerated, are there any side effects?

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.

When can I expect to see first results?

Give 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.

How long does one pack of JOINTS last?

One pack contains 60 capsules and therefore lasts around two months with daily feeding. If your dog receives an extra capsule according to the dosage recommendation, it will last correspondingly less. For continuous feeding we offer value packs.

My dog won't eat the capsule: what can I do?

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 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.

What makes JOINTS special?
Our exclusive joint preparation, tailored for adult dogs, offers targeted support for the joints of adult dogs. For the special needs of younger dogs and particularly sensitive dogs, we recommend JOINTS elements.

Increased strain on the joints, age-related changes (such as osteoarthritis) or breed-typical characteristics (such as hip and elbow dysplasia) place particular demands on the nutrient balance of the musculoskeletal system. JOINTS supports normal joint function with a tailored nutrient combination. In combination with JOINTS greenshell, joint function can be supported further. For age-related changes to the spine, our vitamin B can provide targeted support for the nutrient balance. Our joint preparation can also be a valuable support when the joints are under increased strain.
Can I also give JOINTS preventively?
For precautionary supplementary feeding we recommend our JOINTS elements.

For further questions, such as combining several supplements, medication or the 5 + 1 deal, see our general FAQ.
