Osteoarthritis in dogs is one of the most common chronic diseases, especially as they age. However, many owners take months, or even years, to realize that their dog is in pain.
Why? Dogs are experts at hiding discomfort. What we often interpret as “just getting old” may actually be a disease that is affecting their mobility and overall well-being.
The good news is that early diagnosis, together with appropriate treatment and targeted nutrition, can help manage pain and significantly improve your dog’s quality of life.
What Is Osteoarthritis in Dogs and Why Is It So Difficult to Detect?
Osteoarthritis, also known as arthritis, is a degenerative joint disease. Over time, the cartilage that protects the ends of the bones wears down, causing inflammation, pain, and reduced mobility.
Unlike an acute injury, osteoarthritis progresses slowly.
That is precisely why it often goes unnoticed for a long time. Dogs rarely show pain in an obvious way. Instead of limping constantly, they gradually change their behavior to avoid movements that are uncomfortable for them.
Many owners simply attribute these changes to aging, when in fact there is an underlying condition that can be treated.
Is Your Dog at Risk? Factors and Breeds Most Prone to Osteoarthritis
Although any dog can develop osteoarthritis, several factors significantly increase the risk.
Age
This is the main risk factor. The older the dog, the greater the wear and tear on the joints.
Excess Body Weight
Every extra kilogram places additional stress on the joints, accelerating cartilage deterioration and increasing inflammation.

Previous Joint Injuries
Cruciate ligament ruptures, luxations, fractures, or hip and elbow dysplasia can predispose dogs to earlier onset osteoarthritis.
Genetic Predisposition
Some breeds have a higher
- Labrador Retriever
- Golden Retriever
- German Shepherd
- Rottweiler
- Bernese Mountain Dog
- Newfoundland
- Mastiff
- Saint Bernard
However, small-breed dogs are not exempt, especially those affected by patellar luxation or other orthopedic diseases.
Warning Signs: How to Recognize That Your Dog May Have Osteoarthritis
Symptoms usually appear gradually.
Pay attention if you notice any of these changes:
- Gets up slowly after resting.
- Appears stiff when starting to walk.
- Limps after exercise.
- Avoids running or playing as before.
- Has difficulty climbing stairs or jumping onto the sofa or into the car.
- Walks more slowly during walks.
- Becomes less active.
- Sleeps more than usual.
- Becomes irritable when certain areas are touched.
- Has lost muscle mass in the hind legs.
The more signs you observe, the more advisable it is to visit your veterinarian for an examination.

What Your Veterinarian Can Do and What You Can Do
Osteoarthritis has no cure, but it can be managed and its progression can be slowed down.
Your veterinarian will perform a physical examination and, if necessary, imaging tests such as X-rays to confirm the diagnosis and assess the degree of joint involvement.
From there, he/she can design a treatment plan tailored to your dog, which may include:
- Pain relief and anti-inflammatory medication.
- Physiotherapy and rehabilitation.
- Body weight management.
- Adapted exercise.
- Specific nutrition for joint support.
- Nutritional supplementation when appropriate.
At home, you can also make an important contribution to your dog’s well-being by maintaining a stable routine and avoiding excessive physical strain.
Nutrition as Part of the Treatment: What Should a Dog with Osteoarthritis Eat?
Nutrition plays a key role in both the prevention and management of osteoarthritis in dogs. Although diet alone cannot eliminate a degenerative disease such as osteoarthritis, an appropriate diet can help maintain joint health, support mobility, and contribute to a better quality of life.
Acting before the first signs appear can be especially important in dogs at higher risk, such as breeds predisposed to joint problems, large-breed dogs, or animals with high levels of physical activity.
Prevention: Supporting Joint Health from the Earliest Life Stages
In dogs predisposed to developing joint problems, nutrition can be a very valuable preventive tool.
Providing foods enriched with chondroprotective nutrients, such as glucosamine and chondroitin sulfate, from an early age may help maintain the normal structure and function of the joints. In addition, omega-3 fatty acids, particularly EPA and DHA, contribute to the balance of the inflammatory response.
Within a physiological diet adapted to each dog’s requirements, Summit 10 LIFE STAGES and Summit 10 WHOLE CHOICE include thes nutrients as part of their formulations, providing comprehensive nutritional support for joint maintenance.
In dogs that do not receive a diet enriched with chondroprotective ingredients, the addition of a specific supplement such as Summit 10 CARE Nutritional Support MOBILITY+ may be considered to complement their regular diet.

When Osteoarthritis Is Already Present: Nutritional Support Options
Once osteoarthritis has been diagnosed, nutrition becomes part of the comprehensive management of the disease. Depending on the individual needs of the animal, the veterinarian may recommend different strategies.
MOBILITY Veterinary Diet
When considered appropriate by the veterinarian, one option is to choose a complete dietetic food specifically formulated for dogs with joint problems, such as Summit 10 CARE Veterinary Diets MOBILITY.
This diet has been developed for adult dogs with osteoarthritis and includes selected ingredients designed to support joint metabolism, including:
- Omega-3 fatty acids (EPA and DHA), which help modulate the inflammatory response.
- Glucosamine and chondroitin sulfate, natural components of cartilage that help protect it from degradation and support its maintenance.
- Antioxidants such as vitamins E and C, which help combat oxidative stress caused by free radicals associated with inflammatory processes.
- L-Carnitine, which supports fat metabolism and helps maintain an appropriate body weight while preserving muscle mass.
- Avocado-soybean unsaponifiables, with chondroprotective properties and support for joint well-being.
In addition to providing complete and balanced nutrition, Summit 10 CARE Veterinary Diets MOBILITY represents nutritional support withing the comprehensive treatment plan prescribed by the veterinarian.
MOBILITY+ Nutritional Supplement
In certain cases, the veterinarian may recommend complementing the regular diet with a joint supplement such as Summit 10 CARE Nutritional Support MOBILITY+.
This option may be especially useful when the dog needs to remain on another specific diet due to individual needs (for example, a veterinary hypoallergenic, urinary, or other therapeutic diet), or when changing food is difficult because the dog is strongly attached to its current diet.
Summit 10 CARE Nutritional Support MOBILITY+ provides a combination of selected ingredients for joint care, including:
- Glucosamine
- Chondroitin sulfate
- Methylsulfonylmethane (MSM)
- Hydrolyzed collagen type II
- Palmitoylethanolamide (PEA)
- Antarctic krill meal
Supplements do not replace a complete and balanced diet or veterinary treatment, but they can be part of a comprehensive management plan to help maintain mobility and overall well-being.
Practical Tips to Improve Your Dog’s Quality of Life
In addition to veterinary treatment, small changes at home can make a big difference.
Maintain a Healthy Body Weight
Excess body weight is one of the joints’ greatest enemies.
Short, Frequent Walks
Several moderate walks per day are preferable to one very long walk.

Avoid High-Impact Movements
Reducing jumps from sofas, beds, or cars helps decrease joint stress. Ramps can become a great aid.
Provide a Comfortable Bed
Orthopedic or memory-foam beds reduce pressure on the joints during rest.
Keep Your Dog Active
Complete rest is usually counterproductive. Gentle exercise helps maintain the muscle mass that protects the joints.
Avoid Cold and Damp Conditions
Many dogs with osteoarthritis show greater stiffness in cold or humid environments.
Early Detection Makes the Difference
Osteoarthritis in dogs is a progressive disease, but early diagnosis allows intervention before significant deterioration occurs.
If you notice that your dog no longer enjoys walks as much as before, takes longer to get up, or avoids certain movements, do not attribute it solely to age.
Consult your veterinarian. With appropriate treatment, targeted nutrition, weight management, and a few adjustments to the daily routine, many dogs with osteoarthritis can continue to enjoy an active and comfortable life for many years.
Frequently Asked Questions (FAQs)
At What Age Can Osteoarthritis Appear in Dogs?
Although osteoarthritis is more common in senior dogs, it can appear at any age. Dogs with a genetic predisposition, previous joint problems, excess body weight, or high levels of physical activity may develop signs of joint wear even when they are young. For this reason, in dogs with risk factors, it is advisable to support joint health from an early age through appropriate nutrition and regular veterinary check-ups.
What Symptoms Indicate That My Dog May Have Osteoarthritis?
The signs of osteoarthritis in dogs usually appear gradually and may go unnoticed at first. Common symptoms include difficulty getting up, stiffness after resting, reduced interest in playing, difficulty climbing stairs or jumping, slower walks, limping, or behavioral changes associated with pain. If you observe any of these changes, it is advisable to consult your veterinarian for an assessment.
What Is Better for a Dog with Osteoarthritis: A Veterinary Diet or a Joint Supplement?
It depends on the individual situation of each dog. A complete dietetic food such as Summit 10 CARE Veterinary Diets MOBILITY is specifically formulated for dogs with osteoarthritis and provides nutrition adapted to their needs. In other cases, especially when the dog must remain on another specific diet or continue its regular feeding plan, it may be beneficial to complement the diet with a joint supplement such as Summit 10 CARE Nutritional Support MOBILITY+. The veterinarian should always determine the most appropriate strategy according to the individual needs of the animal.
