Dogs and cats are incredibly resilient, and unlike us, they are experts at masking pain. This instinct to hide weakness means that by the time we notice they’re hurting, the pain is often already quite advanced. Sadly, unrecognized or untreated pain is one of the leading reasons for elective euthanasia in pets of all ages. But the good news is—it doesn’t have to be that way.

One of the most common causes of ongoing pain in pets is osteoarthritis (OA)—a condition where joint tissue wears down over time. It’s far more common than many people realize: studies show that up to 40% of dogs and cats live with OA pain, yet fewer than half ever receive a diagnosis. And while arthritis is often associated with older pets, research has revealed that nearly 1 in 4 dogs under the age of four already show signs of OA pain.

The encouraging news is that OA pain is treatable. Today, veterinarians have safe and effective options, from anti-inflammatory medications to breakthrough monoclonal antibody therapies designed specifically to target OA pain. These treatments can make a world of difference, restoring mobility, happiness, and quality of life.

Signs your pet may be experiencing OA pain include:

• Limping after activity or stopping mid-play

• Sensitivity when being groomed, petted, or picked up

• Slowing down on walks or refusing them altogether

• Stiffness or difficulty getting up after resting

• Trouble jumping onto furniture or favorite perches (especially in cats)

• Hesitation or struggles with stairs

• Noticeable behavior changes, including irritability or aggression

If you’re unsure, tools like the Dog or Cat OA Pain Checklist can help highlight subtle signs you may be missing.

It’s important to remember that chronic pain affects more than just your pet’s body—it also impacts their emotional wellbeing. If you notice any of these changes, don’t wait. Schedule a visit with your veterinarian, so it can be determined the cause and create a treatment plan to get your pet back to feeling their very best.
