How PawSeniors Researches This
PawSeniors articles are written and edited in-house, then checked against primary veterinary sources before publishing.
- Every medical claim is sourced to the American Kennel Club, PetMD, VCA Animal Hospitals, or another named veterinary source, linked at the end of the article.
- We don’t publish AI-generated or unverified health claims, and we don’t accept sponsorship in exchange for editorial content.
- Articles are updated when veterinary guidance changes.
Once joint supplements and environmental changes aren’t quite enough, the conversation with your vet usually turns to prescription pain medication. The options have expanded meaningfully in recent years, and understanding what each one actually does makes that conversation easier to navigate.
NSAIDs: The Standard First Option
Non-steroidal anti-inflammatory drugs remain the backbone of canine arthritis treatment, with carprofen, meloxicam, and grapiprant among the most frequently prescribed in the United States. They work by reducing the inflammation driving arthritis pain, and they tend to act quickly, often noticeably improving comfort within hours of the first dose, which makes them a common starting point when a dog needs relief sooner rather than later. All are given orally, typically once or twice daily depending on the specific drug, as a chewable tablet or liquid, which makes them straightforward to build into a daily routine.
Choosing Between NSAIDs
The three most common NSAIDs aren’t interchangeable, and the choice often comes down to a dog’s specific health profile. Carprofen and meloxicam are traditional NSAIDs with a long track record and strong effectiveness, but they carry a higher relative risk of gastrointestinal and kidney side effects, particularly in dogs with any existing kidney or liver concern. Grapiprant, a newer NSAID that works through a different mechanism, targeting a specific pain receptor rather than broadly suppressing inflammation, is often the first choice for dogs with mild to moderate osteoarthritis, a sensitive stomach, or mild kidney or liver disease, since it tends to be gentler on those organs while still providing meaningful pain relief.
Safety Monitoring Is Not Optional
Every NSAID used long-term requires a prescription and regular bloodwork, typically every three to six months, to monitor kidney and liver function, since these organs process the medication continuously and can be affected even when a dog shows no outward signs of trouble. It’s also worth stating plainly: NSAIDs should never be combined with each other, or with certain other medications like steroids, since doing so dramatically increases the risk of stomach ulcers, gastrointestinal bleeding, and organ damage. If a dog seems to need more relief than one NSAID is providing, the right move is a conversation with your vet about switching or adding a different class of medication, not doubling up on anti-inflammatories.
Librela: A Different Approach Entirely
Librela, the brand name for bedinvetmab, represents a genuinely different category of arthritis treatment: a monoclonal antibody given as a once-monthly injection at the vet’s office rather than a daily pill at home. Rather than broadly reducing inflammation, it works by binding to and neutralizing nerve growth factor, a protein that plays a central role in transmitting arthritis pain signals to the brain. Because it doesn’t work through the same pathway as NSAIDs, it doesn’t carry the same kidney and liver burden, making it a particularly appealing option for older dogs with pre-existing organ concerns that would otherwise complicate NSAID use. For dogs who are difficult to medicate daily, or owners who’ve struggled with pilling, the monthly injection format alone can meaningfully improve how consistently a dog actually receives treatment.
Combining Medications for Better Control
For dogs with more advanced or harder-to-control arthritis pain, vets frequently recommend combining medications from different classes rather than escalating a single drug’s dose. Gabapentin, originally developed as an anti-seizure medication, is commonly added alongside an NSAID or Librela specifically for its separate pain-modulating effects on the nervous system, and the combination of an NSAID plus gabapentin is one of the most commonly prescribed pairings for canine arthritis pain. This layered approach, targeting pain through more than one mechanism at once, often achieves better comfort than pushing any single medication to its upper dose limit.
Choosing What’s Right for Your Dog
The right medication, or combination, depends on your dog’s specific bloodwork, other health conditions, how advanced their arthritis is, and practical factors like how easily they tolerate daily pilling versus a monthly vet visit. None of these options is universally “better”; they’re tools suited to different situations, and a good treatment plan usually starts with whichever option best fits your dog’s individual risk profile, with room to adjust as bloodwork and response to treatment come in over the following months.
Cost and Practical Differences Between Options
Daily NSAIDs are generally the least expensive option upfront, with the main ongoing cost being periodic bloodwork rather than the medication itself. Librela costs more per dose, since it requires a monthly in-clinic visit and injection rather than a pill given at home, but for a dog who’s difficult to medicate daily, or an owner who struggles with consistent pilling, the reliability of a monthly vet-administered dose can offset that cost difference in practice, since a medication that’s actually taken consistently outperforms a cheaper one that’s frequently missed. Gabapentin, when added to either approach, is relatively inexpensive and widely available, making it a low-cost way to add a second mechanism of pain control without a large budget jump.
Signs Your Dog’s Current Plan Isn’t Working
Because arthritis pain tends to progress gradually, it’s worth periodically reassessing whether a medication plan that worked well a year ago is still doing the job, rather than assuming it automatically still is. Watch for a slow return of stiffness after rest, increasing reluctance to do things your dog used to manage fine, like jumping into the car or climbing stairs, or a general dip in activity and engagement that doesn’t have another obvious explanation. Bringing these observations to your vet proactively, rather than waiting for a scheduled recheck, often leads to a plan adjustment, a dose change, an added medication, or a switch to a different class entirely, well before your dog has been quietly uncomfortable for months.
