NSAIDs for Dogs: Which Are Safe and Which Are Dangerous

When your dog is stiff, sore, or slowing down, you want relief for them fast. NSAIDs are one of the most common tools veterinarians use to ease a dog’s pain, and for many dogs they make a real difference in comfort and mobility. But the word “NSAID” covers two very different groups: medicines designed and approved for dogs, and human products that can seriously harm them.

This guide explains what NSAIDs do, which ones are safe when a veterinarian prescribes them, and which ones you should never give your dog. The good news is that there are excellent, dog-specific options. The key is letting your vet choose and manage them. This is general educational information and does not replace advice from your own veterinarian, who knows your dog’s health history.

What NSAIDs do

NSAID stands for non-steroidal anti-inflammatory drug. These medicines lower inflammation, which is your body’s response to injury or wear and tear. By calming inflammation, NSAIDs also reduce pain and bring down fever.

In dogs, vets reach for NSAIDs most often to manage the aches of arthritis and joint disease, to control pain and swelling after surgery, and to ease soft-tissue injuries. For an older dog with creaky hips, the right NSAID can mean the difference between struggling to stand and trotting to the door again.

NSAIDs work by blocking certain natural chemicals that drive inflammation. The catch is that some of those same chemicals also help protect the stomach lining and keep blood flowing to the kidneys. That is why NSAIDs, even the dog-safe ones, have to be dosed carefully and watched over time. The difference between a dog-specific NSAID and a human one is how precisely that balance has been worked out and tested for a dog’s body.

Dog-safe (prescription) NSAIDs

Several NSAIDs have been developed, tested, and approved specifically for dogs. These are prescription medicines, which means a veterinarian must examine your dog and decide whether the drug is appropriate, then set the exact dose. Never assume a dose yourself or buy these without a prescription.

Common dog-specific NSAIDs include:

• Carprofen, one of the most widely used NSAIDs for canine arthritis and post-surgery pain.
• Meloxicam, often given as a liquid, which can make small or precise doses easier to measure.
• Deracoxib, frequently used for pain and inflammation around orthopedic surgery and for ongoing joint disease.
• Firocoxib, another joint-pain option developed for dogs. You can read more on our firocoxib for dogs page.
• Grapiprant, sold as Galliprant, a newer type of NSAID that targets pain signaling in a more focused way and is often chosen for arthritis.

Because these drugs are designed for dogs, your vet knows how a dog’s body handles them and can match the medicine to your dog’s weight, age, and health. Dosing is the vet’s job, not something to guess from a chart or a human label.

Just as important is the monitoring that comes with them. Your veterinarian will usually recommend baseline bloodwork before starting an NSAID and periodic checks while your dog stays on it. These tests look at how the liver and kidneys are doing, so problems can be caught early, often before your dog shows any outward signs.

Human NSAIDs to never give

It is tempting to grab the pain reliever in your own medicine cabinet, but you should never give your dog a human NSAID. The two most common are:

• Ibuprofen (Advil, Motrin)
• Naproxen (Aleve)

These drugs have a narrow margin of safety in dogs, meaning the gap between an amount that does nothing helpful and an amount that causes harm is small. In dogs, even modest amounts can damage the stomach lining and cause painful ulcers and bleeding. Larger amounts can injure the kidneys, and serious cases can become life-threatening.

Naproxen deserves special mention because it stays in a dog’s body for a long time. That gives it more chance to cause damage, and problems can keep developing for a day or more after a dog swallows it.

The reassuring part is that you do not need these products. If your dog is hurting, your veterinarian can prescribe a dog-specific NSAID that does the job safely.

And if your dog has already gotten into a bottle, read what to do if your dog ate human medication and call for help right away.

Aspirin: the special case

Aspirin sits in a gray area. It is an NSAID, it is sold over the counter, and you may have heard of it being given to dogs. But that does not make it a safe choice to reach for on your own.

A veterinarian may sometimes direct you to use aspirin for a short period, but it is generally not a good long-term option for dogs and carries the same kinds of stomach and kidney risks as other NSAIDs. Never start aspirin without your vet’s go-ahead, and never give it alongside another NSAID or a steroid. To understand the details and the cautions, see our aspirin for dogs page, and treat it as information to discuss with your vet rather than a plan to act on by yourself.

Side effects to watch for

Even when a dog-safe NSAID is prescribed correctly, you are an important part of keeping your dog safe. Watch for these warning signs, which can point to stomach or kidney trouble:

• Vomiting or diarrhea
• Dark, black, or tarry stool, which can signal bleeding in the digestive tract
• Loss of appetite or refusing food
• Increased thirst or urination
• Unusual tiredness, weakness, or a change in behavior

If you notice any of these, stop giving the NSAID and call your veterinarian right away. It is always better to check in than to wait and see. Many NSAID problems are far easier to manage when they are caught early.

In an emergency, or if you think your dog has had too much, contact your vet or an animal poison hotline without delay: the ASPCA Animal Poison Control Center at (888) 426-4435 or the Pet Poison Helpline at (855) 764-7661.

Rules that keep NSAIDs safe

A few simple rules cover most of what keeps NSAIDs working safely for dogs:

• Only use an NSAID your vet prescribes for your dog. Dosing is the vet’s job, and dog-specific drugs are the only NSAIDs meant for dogs.
• Never combine NSAIDs with each other or with steroids. Stacking these medicines sharply raises the risk of stomach ulcers and other serious harm. Tell your vet about every medicine and supplement your dog takes.
• Get baseline bloodwork before starting and recheck as your vet advises. This protects the organs that NSAIDs can affect.
• Never share one dog’s NSAID with another pet. A prescription is built around one animal’s weight and health, so what helps one dog could harm another.
• Store all NSAIDs out of reach, since many are flavored or coated and dogs will happily swallow them.

NSAIDs are not something to fear. Used the right way, they are one of the kindest things you can do for a dog in pain. The path to that comfort runs through your veterinarian, who can pick the right medicine, set the right dose, and keep an eye on your dog along the way.
