Healthy joints matter at every stage of a dog’s life. Puppies are still developing, active adult dogs need strong muscles to support movement, and older dogs may become more prone to stiffness or mobility problems. The goal is not to keep a dog constantly active, but to help them move comfortably with a routine that suits their age, breed, body condition and health.
If your dog is already limping, appears painful or has suddenly become reluctant to walk, jump or use stairs, speak to your vet rather than relying on supplements alone. Joint products can be used as part of a wider wellbeing routine, but they are not a substitute for diagnosis or treatment.
Why joint health matters for dogs
A dog’s joints allow the bones to move smoothly against each other. Over time, injury, genetics, age, excess weight and repetitive strain can all affect mobility. Arthritis is one of the most common joint conditions in dogs and can cause stiffness, pain and reduced willingness to exercise.
The PDSA’s guidance on arthritis in dogs highlights regular sensible exercise and maintaining a healthy weight as two important parts of supporting joint health.
1. Keep exercise regular rather than extreme
Consistency is usually more helpful than occasional bursts of intense activity. For many dogs, daily walks, sniffing, gentle play and age-appropriate activity help maintain muscle strength and general fitness.
Dogs that are not used to strenuous exercise can become sore if activity suddenly increases. Build fitness gradually, especially after periods of reduced activity. Older dogs or those with diagnosed joint problems may benefit from shorter, more frequent walks rather than one long demanding walk.
The PDSA also advises that the amount of exercise a dog needs depends on factors such as breed, age, health and personality. You can read their broader dog exercise guidance here.
2. Maintain a healthy body condition
Extra body weight increases the load placed on joints. Even a modest amount of excess weight can make movement harder for a dog that already has stiffness or arthritis.
Feed according to your dog’s needs, measure portions where possible and remember that treats count towards daily calorie intake. If you are unsure whether your dog is overweight, ask your vet or veterinary nurse to assess body condition and recommend an appropriate target.
3. Make your home easier to move around
Small adjustments can make a meaningful difference, particularly for older dogs or dogs recovering from injury.
- Use non-slip mats or rugs on slippery floors.
- Provide a supportive, comfortable bed.
- Keep food and water somewhere easy to reach.
- Reduce unnecessary jumping on and off high furniture.
- Consider a ramp for the car if your dog struggles to jump in.
- Keep nails trimmed, as overgrown nails can affect footing and gait.
4. Watch for early signs of reduced mobility
Joint discomfort does not always appear as an obvious limp. Changes can be subtle. You may notice that your dog:
- takes longer to get up after resting;
- slows down on walks;
- hesitates before climbing stairs;
- avoids jumping into the car;
- seems stiff first thing in the morning;
- becomes less interested in play;
- licks repeatedly around a joint;
- seems more irritable when touched or moved.
These signs can have many causes, so persistent or sudden changes should be checked by a vet.
5. What about joint supplements?
Joint-support products are available in several formats, including powders, chews, tablets, liquids and oils. Common ingredients may include glucosamine, chondroitin, omega-3 fatty acids, green-lipped mussel, collagen or combinations of nutrients.
Ingredients, quality and serving directions vary significantly between products. Look for clear labelling and follow the manufacturer’s guidance carefully. If your dog takes medication, has a medical condition, is pregnant or is on a veterinary diet, check suitability with your vet before introducing a supplement.
You can browse our Joint & Mobility collection for complementary products designed for everyday pet wellbeing.
6. Puppies need a different approach
More exercise is not always better for a growing puppy. Their bones and joints are still developing, so high-impact repetitive exercise should be approached carefully. Play, short walks, training and mental enrichment can help build confidence and fitness without relying on long strenuous sessions.
The PDSA notes that there is no single exercise formula that suits every puppy, and specifically advises against relying on the old “five minutes per month of age” rule as a scientific standard.
7. Senior dogs can still benefit from movement
Older dogs often need exercise adapted rather than stopped. Regular low-impact activity can help maintain muscle tone and prevent long periods of inactivity. The best routine depends on the individual dog and any diagnosed conditions.
If your dog is already showing stiffness, your vet may recommend a combination of weight management, controlled exercise, medication, physiotherapy, hydrotherapy or other treatments.
When should you contact a vet?
Arrange veterinary advice if your dog is limping, appears painful, has a swollen joint, suddenly stops using a leg, struggles to get up, becomes reluctant to exercise or shows a clear change in mobility. Early assessment can help identify the cause and determine the most appropriate treatment.
Frequently asked questions
At what age should I start thinking about my dog’s joint health?
Joint health is relevant from puppyhood onwards. Healthy growth, suitable exercise, good nutrition and maintaining a healthy weight all matter throughout life.
Should an older dog with stiff joints still be walked?
Often yes, but the amount and intensity should be appropriate for the individual dog. Dogs with diagnosed arthritis may benefit from regular controlled, lower-impact exercise. Follow your vet’s advice.
Are joint supplements a replacement for veterinary treatment?
No. They are complementary products and should not replace veterinary assessment, pain relief or other treatment when these are needed.
Can excess weight affect my dog’s joints?
Yes. Additional body weight increases the load on joints and can make mobility more difficult, particularly in dogs with arthritis or previous injuries.
