Piroxicam for Dogs: Benefits, Risks, and What Pet Owners Must Know
Nov, 18 2025
Piroxicam is a nonsteroidal anti-inflammatory drug (NSAID) sometimes prescribed by veterinarians for dogs suffering from chronic pain, especially from arthritis or certain types of cancer. It’s not a drug you can buy over the counter, and it’s not safe for every dog. Used correctly, it can improve mobility and comfort. Used wrong, it can cause serious harm-or even be fatal.
How Piroxicam Works in Dogs
Piroxicam reduces inflammation and pain by blocking enzymes called COX-1 and COX-2. These enzymes produce prostaglandins, chemicals that trigger swelling, fever, and pain. Unlike some newer NSAIDs made just for dogs, piroxicam isn’t selective-it hits both enzymes. That means it’s effective, but also more likely to cause side effects.
It’s commonly used for osteoarthritis in older dogs. One study from the Journal of Veterinary Internal Medicine showed that 68% of dogs with arthritis showed improved mobility after two weeks of piroxicam treatment. It’s also used off-label for transitional cell carcinoma (a type of bladder cancer) because it may slow tumor growth by reducing inflammation around the tumor.
When Vets Prescribe Piroxicam
Most vets won’t start with piroxicam. They usually try safer NSAIDs first-like carprofen, meloxicam, or deracoxib. These are designed specifically for dogs and have a better safety profile. Piroxicam comes into play when:
- Other NSAIDs don’t control pain well enough
- The dog has cancer, especially bladder or nasal tumors
- The dog can’t tolerate other medications due to liver or kidney issues
It’s not a first-line treatment. It’s a backup. And even then, it’s only used if the dog’s bloodwork is normal and the vet believes the benefits outweigh the risks.
Common Side Effects and Warning Signs
Piroxicam is tough on the digestive system. About 1 in 5 dogs will have some kind of reaction. Most are mild, but some are dangerous.
Watch for these signs:
- Vomiting (especially if it’s bloody or looks like coffee grounds)
- Dark, tarry stools (a sign of internal bleeding)
- Loss of appetite lasting more than 24 hours
- Lethargy or weakness
- Yellowing of the gums or eyes (jaundice-sign of liver damage)
- Increased thirst or urination (possible kidney trouble)
If your dog shows any of these, stop the medication immediately and call your vet. Don’t wait. Piroxicam can cause stomach ulcers or kidney failure in as little as 48 hours if the dog is dehydrated or has an undiagnosed condition.
Who Should Never Take Piroxicam
Some dogs should never get piroxicam. These include:
- Dogs under 6 months old
- Dogs with a history of stomach ulcers or gastrointestinal bleeding
- Dogs with kidney or liver disease
- Dogs on other NSAIDs or steroids (like prednisone)
- Dogs with bleeding disorders
- Pregnant or nursing dogs
Even healthy-looking dogs can have hidden problems. That’s why vets always run blood tests before starting piroxicam-and again after a few weeks. A dog might seem fine, but its kidneys could already be under stress.
Dosage and How to Give It Safely
Piroxicam is given once a day, usually with food to reduce stomach upset. The typical dose is 0.3 mg per kilogram of body weight. For a 25kg (55lb) dog, that’s about 7.5 mg daily.
Never guess the dose. Piroxicam comes in 10mg tablets, and splitting them accurately is hard without a pill cutter. Many vets prescribe the 10mg tablet and tell owners to give half for a medium-sized dog. But if you’re not sure, ask for a compounded liquid version-some pharmacies can make it easier to dose small dogs.
Always give it at the same time each day. Missing a dose? Don’t double up. Skip it and go back to the regular schedule. Overdosing increases the risk of serious side effects.
Drug Interactions to Avoid
Piroxicam doesn’t play well with other drugs. Mixing it with these can be dangerous:
- Other NSAIDs (ibuprofen, aspirin, naproxen)
- Corticosteroids (prednisone, dexamethasone)
- Anticoagulants (like warfarin)
- ACE inhibitors (used for heart or kidney disease)
- Diuretics (like furosemide)
Even over-the-counter supplements can interfere. Fish oil, turmeric, and ginger have natural anti-inflammatory effects. Combined with piroxicam, they can increase bleeding risk. Tell your vet about every supplement your dog takes.
Monitoring and Follow-Up
There’s no such thing as a “set it and forget it” prescription with piroxicam. You need regular check-ins.
Most vets require:
- Blood work before starting (to check kidney and liver function)
- Repeat blood work after 7-14 days
- Every 4-8 weeks while on the drug
They’re checking for rising creatinine (kidney stress), elevated liver enzymes, and low red blood cell count (anemia from internal bleeding). If numbers shift, the dose may be lowered-or the drug stopped entirely.
Keep a journal. Note your dog’s appetite, energy, bathroom habits, and any vomiting or diarrhea. Bring it to every vet visit. Small changes matter.
Alternatives to Piroxicam
If piroxicam isn’t right for your dog, there are other options:
- Carprofen or Meloxicam: Safer NSAIDs for long-term arthritis pain
- Gabapentin: Helps with nerve pain and can be used alongside NSAIDs
- Tramadol: A mild opioid for moderate to severe pain
- Physical therapy: Hydrotherapy, laser therapy, and massage improve mobility without drugs
- Weight management: Losing even 10% of body weight reduces joint stress significantly
- Joint supplements: Glucosamine, chondroitin, and MSM can slow cartilage breakdown
For cancer-related pain, some vets combine piroxicam with chemotherapy or radiation. But again, that’s only done under strict supervision.
Real-Life Example: Max, the 11-Year-Old Labrador
Max had severe arthritis. He couldn’t jump onto the couch, and his walks were short and slow. His vet tried meloxicam first. After three weeks, Max was still limping. The vet switched him to piroxicam.
Within five days, Max was walking longer distances and even wagged his tail again. But on day 12, he started vomiting. His owner didn’t think much of it-until the stools turned black. They rushed him in. Blood tests showed internal bleeding and early kidney damage. The vet stopped piroxicam right away. Max recovered after a week of IV fluids and stomach protectants. He’s now on a safer NSAID with regular monitoring.
Max’s story isn’t rare. It’s a reminder that even when a drug works, safety comes first.
What Pet Owners Often Get Wrong
Many owners think:
- “If it helps, I can give more.” → Never. More isn’t better. It’s riskier.
- “My dog seems fine, so I’ll skip the blood test.” → Problems build silently. Bloodwork catches them early.
- “I gave my dog aspirin last year-it helped.” → Aspirin is not safe for long-term use in dogs. It’s not a substitute.
- “I’ll just stop it if he gets sick.” → Stopping suddenly isn’t the issue. The damage is already done.
Piroxicam isn’t a quick fix. It’s a tool. And like any tool, it needs respect.
Final Thoughts: Is Piroxicam Worth the Risk?
For some dogs-with the right diagnosis, careful dosing, and strict monitoring-piroxicam can mean the difference between a painful old age and a good quality of life. For others, the risks are too high.
It’s not about whether the drug works. It’s about whether it’s the right drug for your dog, right now. Talk to your vet about alternatives. Ask for bloodwork. Ask what signs to watch for. Ask what happens if things go wrong.
Your dog’s comfort matters. So does their safety. Don’t choose one over the other. Demand both.
Can I give my dog piroxicam without a vet prescription?
No. Piroxicam is a prescription-only medication. Giving it without veterinary guidance can cause severe side effects, including stomach ulcers, kidney failure, or death. Never use human NSAIDs like ibuprofen or naproxen on dogs-they’re far more dangerous than piroxicam.
How long can a dog stay on piroxicam?
There’s no fixed timeline. Some dogs take it for months under close monitoring. Others need it only for a few weeks. Long-term use increases risk, so vets prefer to switch to safer options when possible. Regular blood tests are required every 4-8 weeks if used beyond a month.
What should I do if my dog misses a dose of piroxicam?
If you miss a dose, skip it and give the next dose at the regular time. Never double up. Overdosing increases the risk of internal bleeding and organ damage. If you’re unsure, call your vet before giving the next dose.
Are there natural alternatives to piroxicam for dog pain?
Yes. Glucosamine and chondroitin supplements can help with joint health. Fish oil (omega-3s) has anti-inflammatory properties. Physical therapy, acupuncture, and weight management are also effective. But these work slowly and aren’t strong enough for severe pain or cancer-related discomfort. They’re best used alongside-or instead of-medication, depending on your dog’s condition.
Can piroxicam cause liver damage in dogs?
Yes. Piroxicam can cause liver enzyme elevations, which may lead to liver damage if not caught early. Signs include yellowing of the gums or eyes, vomiting, loss of appetite, and lethargy. Blood tests before and during treatment are essential to monitor liver function.
Is piroxicam safe for small dogs?
It can be, but dosing is tricky. Piroxicam comes in 10mg tablets, which are hard to split accurately for small dogs under 10kg. Vets may recommend a compounded liquid version or switch to a safer NSAID. Always confirm the exact dose with your vet-never guess.

November 20, 2025 AT 18:37Piroxicam is a beast of a drug-I’ve seen it save my old Lab’s mobility, but man, it’s a tightrope walk. One week he’s bounding like a pup, next week he’s got that weird, quiet lethargy. Bloodwork saved us twice. Always, always test before and every 4 weeks. No exceptions. I keep a little notebook: appetite, stool color, water intake. Tiny changes matter more than you think.
And don’t even think about skipping the vet’s follow-up because ‘he seems fine.’ Dogs hide pain like pros. I once thought my dog was just lazy-turned out his kidneys were whispering for help.

November 21, 2025 AT 10:30so u know what i heard from this guy on youtube who used to work at a vet clinic he said piroxicam is just a money maker for big pharma and the real cause of dog arthritis is grain in their food and they should be eating raw meat and bones like wolves and the vet just wants you to keep buying pills so they can buy their third mercedes

November 22, 2025 AT 23:19Of course the article is ‘balanced.’ But let’s be real: if your dog is on piroxicam, you’re already gambling. The fact that it’s a ‘last resort’ drug says everything. You don’t use a chainsaw to trim hedges. You use it because you’re out of options. And now you’re holding it while your dog’s liver quietly screams.

November 24, 2025 AT 07:38This is one of the most thoughtful, thorough posts I’ve seen on pet meds. Thank you for including the real-life example-it made it personal. I’ve been so scared to ask my vet about alternatives because I didn’t want to seem like I was questioning them. But now I’m bringing my journal and asking for the bloodwork schedule in writing. My 12-year-old Beagle deserves that.

November 26, 2025 AT 05:50Look, I get it-dogs get old, and pain sucks. But piroxicam isn’t magic. It’s a tool. And tools break if you don’t use them right. My dog’s been on it for 8 months. Bloodwork every 6 weeks. No issues. But I didn’t just start it. I did the homework. I talked to 3 vets. I read every study I could find. And I still check his gums every morning. If they’re pale? We’re going in. No waiting. No hoping. Because love means being prepared for the worst.

November 26, 2025 AT 07:11Let me tell you something-I’ve been running agility trials with my 10-year-old Border Collie for years, and when the arthritis hit, we tried everything: glucosamine, acupuncture, laser therapy, even a custom orthopedic bed that cost more than my laptop. Nothing worked. Then we tried piroxicam. Within 72 hours, she was jumping like she was 3 again. I cried. But I also set up a spreadsheet: meds, dates, stool color, water intake, energy levels. I track it like a NASA mission. Because if you’re going to use a drug this powerful, you owe it to your dog to be obsessive. It’s not paranoia-it’s responsibility.

November 27, 2025 AT 08:12There is a metaphysical truth here: pain is not the enemy. Dependency is. Piroxicam does not heal-it masks. And in masking, it creates a false reality where we believe we are caring, when we are merely delaying the inevitable. The dog does not care if you gave it a pill or a hug. It only knows if the pain is gone. But the human? The human is the one who must bear the weight of the choice. And that weight is heavy. So ask yourself: are you treating your dog-or are you treating your guilt?

November 29, 2025 AT 04:32My dog got sick on it. Stopped. He’s fine now. Don’t be a hero. Just listen to your vet. 😔

November 30, 2025 AT 15:56Oh wow, so we’re now treating dogs like terminal cancer patients with NSAIDs? Cute. Next they’ll be giving them chemo in the backyard with a syringe and a prayer. I mean, sure, it works-but at what cost? We’ve turned our pets into pharmaceutical test subjects. And we call it love. Funny how that works.

December 2, 2025 AT 01:11Y’all are acting like piroxicam is the devil. It’s not. It’s just a drug. The real problem? Owners who Google ‘dog pain meds’ at 2 a.m. and then decide they know better than their vet. I’ve seen dogs die because someone gave them aspirin ‘because it’s just like Advil.’ Piroxicam is dangerous? Yes. But so is ignorance. And ignorance kills faster.

December 2, 2025 AT 11:15As an American, I find it disgusting that we let our pets suffer so much that we have to give them drugs that can kill them just to keep them comfortable. In Europe, they have better pain management protocols. We’re behind. And it’s embarrassing. My dog deserves better than a 10mg tablet and a prayer.

December 2, 2025 AT 14:51Important note: Always confirm the exact milligram dose with your vet. Piroxicam is not a ‘one-size-fits-all’ drug. A 5kg dog needs a fraction of a 10mg tablet. Many vets don’t have a 1mg or 2mg tablet available-so ask about compounding. Pharmacies can make a 0.5mg/mL liquid, which is far safer for small breeds. Also: never, ever give it on an empty stomach. Food isn’t optional-it’s protective. And always, always, always monitor hydration. Dehydration + piroxicam = kidney disaster.

December 2, 2025 AT 22:13Let me be the first to say this: piroxicam is the ‘red flag’ NSAID. It’s the one your vet whispers about when they think you’re not listening. It’s the drug they give you when they’re out of polite options. And if your vet prescribes it without a full blood panel and a 30-minute counseling session? Run. Not walk. Run. This isn’t medicine-it’s a Hail Mary. And you’re the one holding the ball.

December 3, 2025 AT 16:55Andrew Montandon nailed it. I’ve been there. My dog Max was on piroxicam for 11 months. We did bloodwork every 5 weeks. Kept a journal. Used a pill cutter. Even switched to a compounded liquid when he got smaller. But here’s the thing: I didn’t just follow instructions. I asked questions. Every time. ‘What if we tried gabapentin instead?’ ‘Could we reduce the dose?’ ‘Is there a safer alternative?’ My vet appreciated it. And Max? He’s 14 now. Still walks. Still wags. Still alive. Because we didn’t just rely on the pill. We relied on vigilance.
Don’t be the owner who says, ‘My vet said it was fine.’ Be the owner who says, ‘My vet and I made a plan.’ That’s what love looks like.
