Arthritis medicine for dogs: every option compared
Checked against FDA and veterinary references: October 2026
Short answer
Most dogs with arthritis do best on a combination: weight control and steady exercise, plus a daily anti-inflammatory such as carprofen, meloxicam or Galliprant, sometimes with gabapentin or amantadine added. A monthly injection, Librela, is another option. Several of these are human medicines a regular pharmacy can fill with your vet’s prescription; others come only through your vet.

How a good arthritis plan fits together
Keeping your dog lean is one of the most effective things you can do for arthritis, because every extra pound adds load to sore joints. Regular, gentle exercise such as leash walks and swimming keeps muscles strong, and physical therapy, ramps, rugs on slippery floors and supportive bedding all help. Medicine works best on top of these, not instead of them.
A daily anti-inflammatory is the usual foundation. Carprofen and meloxicam block the enzymes behind inflammation; Galliprant works more narrowly, blocking one receptor involved in arthritis pain. When one medicine is not enough, vets often add gabapentin or amantadine, or consider Librela, a monthly injection that blocks a protein involved in pain signaling. See our comparisons of Galliprant and carprofen and carprofen and meloxicam.
Safety points
- Your vet will usually check blood work before starting an anti-inflammatory and periodically during long-term use, to watch the kidneys and liver.
- Stop the anti-inflammatory and call your vet for vomiting, black or tarry stools, not eating, increased thirst, or yellowing of the gums or eyes.
- Never combine two anti-inflammatories, or an anti-inflammatory with a steroid such as prednisone, and allow the gap your vet advises when switching.
- Never give human pain relievers such as ibuprofen, naproxen or acetaminophen unless your vet tells you to. See human medicines that are dangerous for pets.
- Gabapentin liquids made for people may contain xylitol, which is poisonous to dogs; use only the product your vet specifies.
What about cats?
Cats get arthritis too, often hidden as reluctance to jump or groom. Solensia, a monthly injection, is approved for arthritis pain in cats. Meloxicam carries a boxed warning in cats because repeated use has been linked to kidney failure, so cats need treatment chosen specifically by a vet. See medicines for cats.
Keeping the cost down
Gabapentin, amantadine and human meloxicam tablets are inexpensive human generics that a regular pharmacy can fill with your vet’s prescription, which often costs less than buying through the clinic. Veterinary products such as carprofen chews and Galliprant come through your vet or a veterinary pharmacy, where prices differ, so compare. See which pet medicines a regular pharmacy can fill.
Frequently asked questions
What is the best arthritis medicine for dogs?
There is no single best one. A dog anti-inflammatory such as carprofen, meloxicam or Galliprant is usually the foundation, with weight management and exercise, and add-ons or Librela when more relief is needed. Your vet chooses based on your dog’s age, kidney and liver health and response.
Can I give my dog ibuprofen or aspirin for arthritis?
No. Ibuprofen and naproxen can cause stomach ulcers and kidney failure in dogs at doses people use, and aspirin causes stomach bleeding and interferes with proper treatment. Never give human pain relievers unless your vet tells you to.
Is Librela safe?
Librela is FDA-approved and helps many dogs. In December 2024 the FDA alerted veterinarians to reported adverse events after Librela, including unsteadiness, weakness and seizures, and asked them to discuss these with owners. Report any change in your dog after a dose to your vet.
Can my dog take two arthritis medicines together?
Some combinations are common, such as an anti-inflammatory with gabapentin or amantadine. Two anti-inflammatories, or an anti-inflammatory with a steroid such as prednisone, must never be combined, and a gap is usually left when switching between anti-inflammatories.
Do joint supplements work?
Supplements are not FDA-approved medicines and quality varies. The evidence is strongest for omega-3 fatty acids from fish oil; ask your vet about a suitable product and dose.
