Can My Dog Have Aleve? Why Naproxen Is Dangerous for Pets
Timely recognition of pet painkiller toxicity can save lives and ease recovery.
Can My Dog Have Aleve?
Many pet owners wonder if it’s ever safe to give their dog Aleveâthe over-the-counter pain reliever commonly used by people. The short and crucial answer is: no, dogs should never be given Aleve (naproxen). Even a single tablet can be fatal to dogs. Understanding why naproxen is dangerous, what symptoms to watch for, and what safer alternatives exist can help you protect your dog’s health.
What Is Aleve?
Aleve is a brand name for naproxen, a non-steroidal anti-inflammatory drug (NSAID) regularly used by people to relieve pain, reduce inflammation, and lower fever. Aleve is widely available over-the-counter. While generally safe for humans at recommended doses, naproxen is uniquely toxic to dogs and should never be administered to pets.
Why Is Aleve (Naproxen) Dangerous for Dogs?
The toxicity of naproxen in dogs is due to key differences in how their bodies metabolize and eliminate the drug. In humans, naproxen passes out of the system efficiently through urine. However, according to veterinary expert Dr. Jennifer Sperry, dogs eliminate the medication much more slowly via the liver, and some naproxen is reabsorbed into the bloodstream during digestion. This leads to higher and longer-lasting concentrations of the drug in the dog’s body, rapidly reaching toxic levelsâeven at low doses.
As little as a single 220mg tablet can cause significant harm, including internal bleeding, kidney failure, and death.
What Makes Human Painkillers Unsafe for Dogs?
- Human medications are formulated for adult body weights and organ function, not for dogs.
- Dogs metabolize drugs like naproxen much more slowly, causing the drug to accumulate and reach toxic levels.
- NSAIDs like Aleve, Advil (ibuprofen), and Tylenol (acetaminophen) cause severe gastrointestinal, kidney, and liver damage in dogsâeven at low doses.
Symptoms of Naproxen (Aleve) Poisoning in Dogs
If your dog has ingested naproxenâeven a small amountâsymptoms can develop within a few hours but may worsen over the next days. Common clinical signs of Aleve poisoning include:
- Vomiting (often with blood)
- Loss of appetite
- Lethargy or weakness
- Diarrhea
- Pale or discolored gums
- Stomach ulcers and gastrointestinal bleeding
- Abdominal pain
- Seizures (in severe cases)
- Increased thirst or urination (due to kidney injury)
- Jaundice (yellowing of eyes/gums if liver is affected)
Worst-case outcomes include irreversible organ damage, collapse, and death if not treated promptly.
What To Do If Your Dog Ate Aleve
This is a veterinary emergency. If your dog has eaten Aleve or shows any signs of poisoning, take these steps immediately:
- Contact your veterinarian or an emergency animal clinic right away. Do not wait for symptoms to appearâprompt action is critical.
- Call a pet poison helpline for immediate advice. (U.S. Pet Poison Helpline: 855-764-7661.)
- Bring the Aleve packaging or bottle with you. This helps the vet identify the exact dosage and formulate a treatment plan.

Quick treatment offers the best chance for recovery. Dogs may require hospitalization, IV fluids, medications to protect the stomach, anti-nausea drugs, and in severe cases, interventions for kidney or liver injury.
How Do Vets Treat Naproxen Poisoning?
Treatment depends on the amount ingested, time since exposure, and the dog’s size and health. Common steps include:
- Decontamination: Inducing vomiting (if ingestion was recent and under veterinary supervision) or administering activated charcoal to limit additional drug absorption.
- Supportive care: IV fluids to support kidney function and flush toxins.
- Medications: Antacids and stomach protectants (e.g., sucralfate, famotidine), anti-nausea and gastroprotective medications.
- Monitoring: Hospitalization for close monitoring of organ function (kidney, liver, gut).
- Bloodwork: To assess the extent of poisoning and organ injury.
- Severe cases: May require blood transfusions or emergency interventions if there is severe bleeding or organ failure.
Prognosis
Aleves toxicity is extremely serious and can be fatal, especially if not treated quickly. However, with fast and aggressive intervention, some dogs can recover. The earlier veterinary help is obtained, the better the chances of survival.
Common Mistakes: Why People Give Human Medications
- Assuming whatâs safe for people is safe for pets. Dogs process drugs differently, often with life-threatening results.
- Mistaking dosage. Human doses are much higher than what a dogâs body can safely handle.
- Trying to provide quick pain relief at home. Well-meaning owners want to help but may cause greater harm.
To prevent accidental poisoning, always store medications out of reach of pets, and never administer any drug to your dog without explicit veterinary direction.
Safe Alternatives: What Can You Give a Dog for Pain?
Never give your dog any over-the-counter human pain medication unless prescribed by a veterinarian. However, there are pain relief options that your vet may recommend. These include:
- Veterinary NSAIDs: Drugs specifically developed and approved for dogs, such as carprofen (Rimadyl), meloxicam (Metacam), firocoxib (Previcox), and deracoxib (Deramaxx).
- Other veterinary-prescribed pain medications: Your vet may occasionally prescribe additional drugs for severe pain, such as gabapentin, amantadine, or opioids, but only under strict supervision.
Never attempt to dose your dog yourself. Your veterinarian will recommend the safest medication, dosage, and plan based on your dogâs specific needs, underlying conditions, and concurrent medications.
Comparison Table: Common Human Painkillers and Toxicity in Dogs
| Generic Name | Brand Names | Used in Dogs? | Main Dangers |
|---|---|---|---|
| Ibuprofen | Advil, Motrin | No | Kidney failure, GI bleeding |
| Naproxen | Aleve, Naprosyn | No | Kidney failure, internal bleeding, death |
| Aspirin | Bayer, Ascriptin | Only under strict vet supervision | Stomach ulcers, bleeding |
| Acetaminophen | Tylenol | Only under strict vet supervision | Liver injury, red blood cell damage |
| Prescription NSAIDs (for dogs) | Rimadyl, Previcox | Yes, under vet guidance | Side effects possible, but much safer when dosed correctly |
How to Prevent Accidental Poisoning
- Store all medications securelyâin child- and pet-proof containers, out of reach.
- Never leave pills on countertops or in open purses, bags, or pill organizers where pets can access them.
- Educate family members and visitors about the risks of sharing human drugs with pets.
- Dispose of unused medications properlyâdonât leave expired or unused pills where pets may investigate.
When To Call the Vet: Recognizing a Pain Emergency
If your dog is in pain, contact your vet rather than reaching for a home remedy. Signs itâs time to call the vet include:
- Whimpering or vocalizing
- Limping or trouble standing/walking
- Sudden lethargy or drop in activity level
- Loss of appetite
- Panting, restlessness, or hiding
Timely veterinary assessment can address your dogâs pain safely and effectively, restoring well-being without unnecessary risk.
Frequently Asked Questions (FAQs)
Q: Can dogs have any pain medication meant for people?
A: No. Most human pain medications, including Aleve, ibuprofen, Tylenol, and aspirin (in most situations), are toxic to dogs and should never be given unless specifically instructed by a veterinarian.
Q: How fast can Aleve poisoning happen in dogs?
A: Naproxen can be absorbed in as little as three hours. Symptoms often appear quickly and can escalate to life-threatening complications within a day if left untreated.
Q: What should I do if my dog accidentally eats a naproxen pill or any human medication?
A: Immediate action is essential. Contact your veterinarian or the Pet Poison Helpline. Do not induce vomiting at home unless advised; treatment is more effective the sooner it starts.
