Osteoarthritis and Joint Pain in Aging Dogs
What Is Osteoarthritis?
Osteoarthritis is a degenerative joint disease that results from the breakdown of cartilage, causing pain, inflammation, and reduced mobility. It’s especially common in large breeds, overweight dogs, and senior pets.
Signs to Watch For:
- Limping or favoring one leg
- Stiffness after sleep or inactivity
- Difficulty climbing stairs or jumping
- Decreased interest in play or walks
Management Options:
- Weight control to minimize joint strain
- Joint supplements like glucosamine, chondroitin, and omega-3s
- Low-impact exercise such as swimming or short, gentle walks
- Pain relief through NSAIDs, laser therapy, or acupuncture

Preventive Care Strategies for Senior Dogs
Regular Wellness Exams
As your dog ages, routine vet visits do more than monitor health—they help you stay ahead of changes that can impact your pet’s comfort and quality of life. These check-ins are a chance to catch subtle shifts before they become serious problems and adjust care as needed.
At Pinedale Animal Hospital, we recommend:
- Biannual wellness exams to keep a close eye on evolving needs
- Blood and urine screenings to catch organ changes early
- Heart, lung, and joint assessments to monitor aging systems

Nutrition and Supplements
A healthy diet makes a big difference in how your senior dog feels day to day. As metabolism slows and certain conditions emerge, targeted nutrition becomes essential.
- Senior dog formulas support digestion, immunity, and joint health
- Weight control is key to reducing strain on aging joints and organs
- Joint supplements and omega-3s can help ease arthritis and stiffness
- Antioxidants like vitamin E may help delay cognitive decline

Keeping Them Moving—Body and Brain
Movement is medicine for aging dogs. While their pace may be slower and their play sessions shorter, physical and mental activity remains essential for maintaining strength, flexibility, and overall happiness.
Even if your dog has arthritis or mobility challenges, there are gentle ways to keep them engaged:
- Short, consistent walks help keep joints limber and minds sharp
- Strolling around the block or the yard allows them to sniff, explore, and stay mentally stimulated
- If walking is too hard, try a pet wagon or stroller so they can still enjoy the sights and smells of the outside world
- Puzzle toys, scent games, and simple training exercises help keep their brains active and spirits high
- Swimming (if accessible and safe) is a great low-impact option for dogs with joint pain
You know your dog better than anyone—watch for what brings them joy and adapt activities to their comfort level. At this stage, it’s less about how far they go and more about helping them stay connected to the world around them.
Give Your Dog the Comfortable Retirement They Deserve
Your dog’s golden years can still be full of love, comfort, and joy. With regular veterinary care, early disease detection, and a supportive home environment, you can make these years some of the best yet.
