How ProDog Flexx Works
This advanced fusion of ingredients benefits 5 key areas:

This exclusive blend of methyl-sulfonyl-methane (MSM) and hemp protein helps to maintain balanced MSM levels (important in ageing) and assists the body’s natural recovery mechanisms; supporting joint, ligament and muscle rehabilitation.
Rich in chlorella growth factor and enhanced with nucleic acid, this powerhouse combination supports the integrity of the immune system, aiding optimal immune function in dogs of all ages.
The primary ingredients, green-lipped mussel, boswellia and turmeric are formidable superfoods, known to help support the natural systems controlling inflammation and thus aid mobility, flexibility and ease of movement.
The fish collagen, hemp and green-lipped mussel component of this formula make it a plentiful source of Omega 3, 6 & 9 fatty acids – essential nutrients that support maintenance of brain and gut function, physical health and optimal skin and coat condition.
The balanced blend of glucosamine sulphate, chondroitin and green-lipped mussel provides joint health support. This nutritional partnership assists the body’s natural formation of keratin, collagen and elastin, aiding flexibility, tone and strength in a dog’s bones and joints.

My 11 year old border collie had an accident when he was 5. He has been given Flexx ever since then and he walks for miles with no lameness.

Our nearly 8 year old Labrador has been on Flexx since January, we had noticed she was stiff and hesitant to jump onto bed. On the third pot of Flexx now and she seems almost puppy like again!

Joint supplements for dogs are an effective way to provide preventative joint care for any dog and nutritional support for those with discomfort and immobility. Nutritional joint care supplements can be especially helpful for large breed, older dogs or those that are prone to suffering with mobility issues.
Powerful ingredients, such as those in ProDog Flexx, are carefully selected by canine nutrition experts to work in synergy, providing a simple way to incorporate dietary support that aids your dog’s joint health, ultimately helping them get the best out of life.
Joint supplements for dogs can help maintain mobility and freedom of movement by providing a simple dietary addition that supports joint health.
Signs your dog may benefit from a nutritional joint care supplement are:
- Struggling to get up after resting
- Being unable to jump up into the car or onto the couch.
- Reluctance to sit or lie down – and not because they are disobedient – simply because they have stiff or sore joints.
- Limping or odd shuffling when walking, or bunny hopping
- Panting excessively (this can indicate pain or discomfort).
We recommend seeking advice from a vet to rule out serious conditions which may also require medical treatment. ProDog Dog joint supplement, Flexx, is not a medicinal product; therefore can be added to any dog food and fed as a nutritional complement to veterinary care.
Why might your dog need joint supplements? There are a number of reasons to introduce nutritional joint support to your dog’s diet, some of which we have listed below:
- Some large breed dogs are prone to joint issues, therefore nutritional support can help to maintain joint health.
- Breed-specific joint related conditions – for example, some smaller dogs including Shih Tzus, are prone to luxating patella.
- Mobility support – dog joint supplements can aid joints and cartilage strength to support mobility, especially in large, heavy and very active breeds.
- Nutritional supplementation can contribute to the support of inflammatory conditions such as arthritis and mobility related pain.
As your dog ages, their ability to produce the essential proteins that build and strengthen joints, significantly decreases. This leaves them vulnerable to a whole host of joint issues including arthritis, hip and elbow dysplasia, cruciate issues and more. A dietary joint supplement for dogs can help to maintain the molecules and protein levels crucial to joint health in all dogs, including senior, active, working and sports dogs.
We recommend that you don’t give ProDog Flexx joint supplement to dogs under the age 24 weeks. Once they are 24 weeks old, you can start adding it to their food to give them the best start.
