Recognizing Early Signs of Arthritis in Pets

Pets age quietly. They don’t complain, they don’t sigh dramatically, and they certainly won’t tell you their joints are stiff in the morning. But arthritis, a degenerative joint disease that affects both cats and dogs, is far more common than many pet owners realize—especially as pets reach their senior years.

The tricky part? Early signs of arthritis are subtle. Many animals simply adapt to the discomfort, masking symptoms until the disease is more advanced. That’s why being tuned in to the small changes—those tiny shifts in routine, posture, or mood—can make all the difference in catching arthritis early and managing it effectively.

Here’s how to recognize the signs, what to look for in both dogs and cats, and what steps you can take if arthritis is creeping in.

What Exactly Is Arthritis in Pets?

Arthritis, or osteoarthritis, is the progressive deterioration of joint cartilage and the surrounding tissues. Over time, inflammation and pain increase, mobility decreases, and everyday activities can become challenging.

While it’s more common in senior pets, arthritis can also affect younger animals due to injury, genetics, or joint disorders like hip dysplasia or elbow dysplasia. Large breeds, overweight pets, and those with a history of orthopedic problems are especially at risk.

Subtle Signs in Dogs: What to Watch For

Dogs are often more demonstrative than cats, but early arthritis symptoms can still be overlooked. These changes tend to creep in gradually:

• Slower to rise from lying down, especially after naps
• Hesitating on stairs or needing a boost into the car
• Limping, stiffness, or an uneven gait after exercise
• Less interest in long walks or playtime
• Lagging behind on walks where they used to lead
• Licking or chewing at joints
• Changes in posture or stance
• Irritability when touched near joints

Owners sometimes chalk this up to "slowing down with age," but if you’re noticing any combination of these signs, it’s worth having a conversation with your vet.

Subtle Signs in Cats: Masters of Hiding Discomfort

Cats are famously stoic and will often endure joint pain without complaint. But that doesn’t mean the signs aren’t there—they're just easier to miss.

Keep an eye out for:

• Jumping less, or avoiding favorite high spots
• Using furniture as “steps” instead of jumping in one go
• Taking longer to get to food bowls or litter boxes
• Less grooming (especially around the back or hips)
• Matted fur from lack of mobility
• Sudden changes in temperament—grumpiness, hiding, or resistance to being held
• Accidents outside the litter box due to discomfort getting in and out

Even a once-active cat can slowly become more sedentary. That shift deserves a closer look.

What Causes Arthritis in Pets?

While age is a factor, arthritis isn’t just a “senior issue.” Some common contributors include:

• Joint injuries or repetitive strain
• Obesity, which puts excess pressure on joints
• Genetic predispositions (common in breeds like Labs, Shepherds, and Maine Coons)
• Infections or autoimmune disease affecting the joints
• Previous surgeries or orthopedic problems
• Poor nutrition during growth stages

Prevention and early management go a long way—so identifying the problem early gives you more treatment options.

What You Can Do

If you suspect arthritis, don’t wait. Early intervention can significantly improve your pet’s quality of life.

• Schedule a veterinary exam: Your vet may perform a physical exam, X-rays, or other imaging to assess joint health
• Consider weight management: Extra pounds = extra pain. A slim pet is a more comfortable one
• Discuss joint supplements: Glucosamine, chondroitin, omega-3s, and green-lipped mussel extract are often recommended
• Explore physical therapy: Underwater treadmills, massage, and stretching exercises can ease stiffness
• Ask about pain management: This could include NSAIDs, acupuncture, or newer regenerative therapies like PRP or stem cell treatment
• Make your home easier to navigate: Pet stairs, ramps, rugs for traction, and orthopedic beds all help reduce stress on joints

Consistency and early action are key. The goal isn’t just mobility—it’s giving your pet more pain-free days, more tail wags, more curiosity, more comfort.

Aging Gracefully Doesn’t Have to Hurt

Your pet may not tell you they’re aching—but their body will. Catching arthritis early means more options, less pain, and a better long-term outlook. It allows you to support them in doing what they love, whether that’s chasing a tennis ball or curling up on a favorite perch in the sun.

So pay attention to the quiet clues. When a pet starts moving less, they might not be lazy or just “getting old.” They might just need your help.

And helping them feel better? That’s one of the best things you can do.
