NSAIDs for Dogs: The Options Compared
Non-steroidal anti-inflammatory drugs (NSAIDs) are the mainstay of canine pain relief, and carprofen is the most widely prescribed of them. They work by blocking the COX enzymes that produce inflammatory prostaglandins, which reduces pain, swelling and fever. Several are approved for dogs, they are broadly comparable in effect, and the same core risks apply to all of them: digestive upset, and less commonly liver or kidney effects.
Ibuprofen, naproxen and aspirin are dangerous for dogs at doses people take without a second thought. Dogs metabolise them very differently, and ibuprofen in particular is a common cause of serious gastrointestinal and kidney injury in dogs. Never give a human NSAID without explicit veterinary direction — see carprofen vs ibuprofen.
The NSAIDs Vets Prescribe for Dogs
| Drug | Familiar brands | Notes |
|---|---|---|
| Carprofen | Rimadyl, Novox, Vetprofen, Carprovet, Carprieve | The most widely prescribed canine NSAID; many FDA-approved generics keep cost down |
| Meloxicam | Metacam | Often supplied as an oral liquid, which suits precise dosing in small dogs |
| Firocoxib | Previcox | A coxib-class NSAID, more COX-2 selective |
| Deracoxib | Deramaxx | Another coxib-class option, used for osteoarthritis and post-operative pain |
| Grapiprant | Galliprant | Not a traditional NSAID: it blocks a specific prostaglandin receptor rather than COX enzymes |
No one of these is universally best. Vets choose based on the dog's health history, what has been tolerated before, the dosing form that suits the household, and cost.
How They Compare in Practice
- Meloxicam vs carprofen — the liquid-versus-tablet question, and why small dogs are often on meloxicam.
- Galliprant vs carprofen — a different mechanism, sometimes chosen for dogs with a higher GI or kidney risk profile.
- Carprofen vs Rimadyl — brand versus generic within the same drug.
- Carprofen vs prednisone — an NSAID versus a corticosteroid, and why the two are not combined.
Risks That Apply to Every Canine NSAID
Prostaglandins do not only drive inflammation; they also help protect the stomach lining and regulate kidney blood flow. Blocking them is therefore never entirely without consequence, whichever NSAID is used. The warning signs are the same across the class:
- Repeated vomiting, or blood in vomit or stool
- Black or tarry stool
- Yellowing of the gums, eyes or skin
- A marked increase in drinking or urinating
- Loss of appetite, or unusual lethargy that does not settle
Never combine two NSAIDs, or an NSAID with a corticosteroid such as prednisone, unless your vet has specifically planned it with a washout period — that combination sharply raises the risk of stomach ulceration. See carprofen drug interactions and carprofen side effects in dogs.
Monitoring and Alternatives
For long-term use, vets typically run bloodwork before starting and recheck periodically to confirm liver and kidney values remain normal — see bloodwork monitoring.
NSAIDs are also not the only tool. Weight management, physiotherapy, joint supplements, monoclonal antibody injections and joint injections all play a part in managing canine osteoarthritis, often alongside an NSAID rather than instead of one. See carprofen alternatives.
Frequently Asked Questions
What is the best anti-inflammatory for dogs?
There is no single best option. Carprofen is the most widely prescribed canine NSAID, but meloxicam, firocoxib, deracoxib and grapiprant are all used, and the right choice depends on the dog's health history, tolerance, dosing form and cost.
Can I give my dog ibuprofen?
No. Ibuprofen is dangerous for dogs and is a common cause of serious gastrointestinal and kidney injury. Only give a dog an NSAID approved for dogs and prescribed by a vet.
Is carprofen an NSAID?
Yes. Carprofen is a non-steroidal anti-inflammatory drug of the propionic acid class, approved specifically for dogs.
Can dogs take two NSAIDs together?
No. Combining two NSAIDs, or an NSAID with a corticosteroid such as prednisone, sharply increases the risk of stomach ulcers and kidney injury. Switching between them requires a washout period planned by your vet.
Are there non-NSAID options for dog arthritis?
Yes. Grapiprant (Galliprant) works through a different mechanism, and weight management, physiotherapy, joint supplements and injectable treatments are all used, often alongside an NSAID.
Which NSAID is safest for dogs with kidney problems?
That is a decision for your vet after bloodwork. All NSAIDs affect kidney blood flow to some degree, so dogs with kidney disease need individual assessment rather than a general recommendation.
