Arthritis in Dogs and Cats

August 26, 2025

Thanks to advancements in veterinary medicine and the dedication of pet owners, our dogs and cats are living longer than ever. However, with longer lives come age-related health challenges, including arthritis. Just like humans, pets experience joint degeneration over time, leading to pain and mobility issues.

Arthritis commonly develops in dogs around age five or six, depending on breed, and in cats around age seven or eight. However, injuries to bones, tendons, or ligaments earlier in life can accelerate its onset. Recognizing the signs and taking proactive measures can help manage arthritis and improve your pet’s quality of life.

Understanding Arthritis in Pets

Arthritis occurs when the protective cartilage in the joints wears down, causing inflammation, stiffness, and pain. Without proper cushioning, bones grind against each other, leading to discomfort and reduced mobility. Pets with arthritis may struggle to stand up, hesitate before jumping, or show a decrease in overall activity.

While arthritis is a progressive condition, early intervention can slow its advancement and help keep pets comfortable for years to come.

Supplements for Joint Health

Certain supplements can support joint health and reduce the impact of arthritis:

  • Glucosamine & Chondroitin: These compounds help protect cartilage from deterioration and minimize bone-on-bone friction, a key source of arthritis pain. Large-breed dogs benefit most from starting a glucosamine and chondroitin regimen as early as age two or three.
  • Fish Oil: Rich in omega-3 fatty acids, fish oil has anti-inflammatory properties that support joint health and mobility. Giving fish oil twice daily may help reduce stiffness and discomfort.

Since pet supplements are not regulated by the FDA, it’s crucial to purchase them from a veterinarian or a reputable source to ensure quality and effectiveness.

Pain Relief Options

When arthritis progresses, pets may require pain relief to stay comfortable. Several options are available, but they should always be used under veterinary supervision:

  • Non-Steroidal Anti-Inflammatory Drugs (NSAIDs): These medications help reduce pain and inflammation in dogs with advanced arthritis. However, they can have side effects, so a veterinarian should perform blood work and a full exam before prescribing them.
  • Tramadol: In cases of severe pain, Tramadol may be prescribed as an additional pain management option for dogs.
  • Pain Relief for Cats: Treating arthritis in cats is more challenging because they do not tolerate many pain medications well.
    • Important Warning: Never give human pain relievers such as aspirin, ibuprofen, or naproxen to pets without consulting a veterinarian. These medications can be highly toxic and even fatal.

Recognizing Arthritis in Your Pet

Early detection of arthritis can help slow its progression and improve your pet’s comfort. Signs to watch for include:

  • Stiffness or difficulty standing up after resting.
  • Hesitation or refusal to jump onto furniture, beds, or into the car (dogs).
  • Increased inactivity, reluctance to move, or sitting in one place for long periods (cats).

If you notice these signs, consult your veterinarian for an evaluation and discuss treatment options.

Conclusion

Arthritis is a common condition in aging pets, but with early intervention, joint supplements, and proper pain management, your dog or cat can maintain a good quality of life. Regular veterinary checkups, a balanced diet, and appropriate exercise can all contribute to keeping your pet comfortable and mobile for years to come.

If you suspect your pet may have arthritis, schedule an appointment with your veterinarian to discuss the best course of action.
