Joint Health for Pets: Signs, Causes, and Support

Supporting joint health in cats and dogs means keeping cartilage, synovial fluid, and surrounding muscles working smoothly so your pet can move comfortably and stay active as they age.

Joint dysfunction is common in older pets, and dogs in particular are prone to osteoarthritis. Osteoarthritis is inflammation inside the joint that can cause pain and a gradual breakdown of articular cartilage, which can make everyday movement feel harder over time.

The first thing is to be aware of the signs that your pet is feeling sore. Look out for:

• Limping
• Reluctance to move, especially in the mornings
• Lack of enthusiasm for walks or playtime
• Difficulty jumping onto furniture or navigating stairs
• Excessive grooming in one area

A visit to the vet is in order with any change of behaviour. If your furry family member does have arthritis, your vet may recommend medication and lifestyle changes like weight management, gentle daily movement, and supportive bedding to reduce strain on sore joints.

You may also consider a nutritional supplement that complements a vet-led plan. Being petlovers ourselves, we have designed one! Our pet product, Petifort, is backed by science and appealing to pets. All the ingredients are human consumption grade, though the taste is probably more attractive to someone that doesn’t mind fish breath.

But what are the main ingredients?

Collagen Hydrolysate & Hyaluronic Acid

Collagen is a key component of cartilage. Collagen hydrolysate is an enzymatically treated, highly digestible, purified product that provides building blocks for cartilage and includes amino acids linked with healthy inflammatory balance. Animal studies using radioactively labelled collagen hydrolysate have shown that oral intake leads to accumulation in cartilage tissue7 where it functions to synthesise the cartilage matrix8. There are numerous studies showing a positive effect on arthritis symptoms, collagen maintenance and bone health in humans8 and animals. A 2010 double-blind, placebo controlled study showed that 10g of collagen hydrolysate for 8 weeks significantly improved stiffness, lameness and activity levels in 15 arthritic dogs6. Boosting the effects of collagen is a hefty dose of hyaluronic acid, a component of synovial fluid that helps joints glide and cushion movement. Supplemental hyaluronic acid is well known for alleviating joint symptoms in humans11, and is well absorbed by animals.

Green Lipped Mussel

A multitude of studies show that New Zealand Green Lipped Mussel (perna canaliculus) offers benefits in the management of joint pain syndromes in humans and animals4,5,6. Our New Zealand sourced mussel powder is rich in Omega 3 fatty acids, vitamins, minerals, amino acids, chondroiton and other glycosaminoglycans. The latter act as lubricant and shock absorber within the joint and make up 95% of the proteoglycans required to construct connective tissue such as tendons and cartilage. Randomised, placebo controlled trials and field trials in dogs have shown improvements in total arthritic score of up to 30%, with improved joint pain and joint swelling as well as improved veterinary-assessed mobility5,6,10,11.

Vitamin C

Vitamin C is necessary for cartilage formation and maintenance and also acts as an antioxidant. Although dogs do produce their own vitamin C, this ability can diminish as they age.

Boron & Manganese

Boron is a trace element, the global concentration of which varies widely and correlates with incidence of arthritis. Arthritic bone contains less boron than normal bone3. Manganese is a trace mineral that has an important role in bone and cartilage development. It can activate enzymes that are necessary for the formation of polysaccarides and glycoproteins, including glycosaminoglycans which are a component of cartilage. A deficiency of manganese limits the rate of glycosaminoglycan synthesis13.

Petifort is in powder form, and can be sprinkled on your pet’s food. In addition to joint health support, our customers have told us that their pets like the taste and show an increased interest in food, which can be helpful when appetite dips with age.

FAQ

What are the earliest signs of joint problems in pets?

Early signs often include stiffness after rest, subtle limping, or hesitating to jump and use stairs. These changes can happen gradually as joints become sore and movement feels less comfortable. If you notice a new pattern for more than a few days, book a vet check and keep activity gentle until you have a plan.

What causes osteoarthritis in dogs?

Osteoarthritis is usually driven by wear and tear, past injury, or joint shape issues that increase friction in the joint. Inflammation can then accelerate cartilage breakdown and make movement painful. Keeping your dog at a healthy weight and building steady, low-impact exercise can reduce the daily load on joints.

How does weight affect joint pain in pets?

Extra body weight increases the force going through hips, knees, and elbows with every step. That higher load can worsen inflammation and speed up cartilage wear. Even small weight loss can make a noticeable difference, so ask your vet for a target weight and a simple feeding plan.

What does supporting joint health in cats and dogs include day to day?

It usually includes appropriate movement, a healthy body condition, and nutrition that supports cartilage and joint fluid. The goal is to keep joints moving smoothly while reducing flare-ups from overdoing it. Use short, regular walks for dogs, add ramps or steps for furniture, and make litter boxes easy to access for cats.

Do supplements help with pet joint health?

Supplements can help support comfort and mobility when they complement a vet-guided plan. Ingredients like collagen, hyaluronic acid, and green lipped mussel are used because they support cartilage structure and joint lubrication. Choose products with clear dosing and consistent daily use, and track changes in movement over 4 to 8 weeks.

Why is green lipped mussel used for joints?

Green lipped mussel contains omega 3s and other compounds that support a healthy inflammatory response. It also provides nutrients involved in connective tissue and joint function. For best results, use it daily and pair it with gentle exercise rather than relying on supplements alone.

When should I see a vet about limping or stiffness?

You should see a vet any time limping, stiffness, or reduced activity is new, worsening, or linked with yelping or swelling. Pain can change how your pet moves and can lead to compensations that strain other joints. A prompt assessment helps you rule out injury and start the right mix of treatment and lifestyle support.
