If your dog is in pain, is it okay to give them an aspirin or two?
While veterinarians may prescribe aspirin for dogs in certain situations—like pain relief or inflammation—there are important considerations pet parents should make before reaching into their medicine cabinet and administering aspirin to their canine companions.
Most importantly, your dog shouldn't consume human medications. Human drugs are overwhelmingly unsafe for pets for a number of serious reasons.
Can You Give Dogs Aspirin?
The only human aspirin sometimes recommended by veterinarians for dogs is baby aspirin, due to its low dosage. Still, even low dose aspirin is typically an enteric-coated aspirin, which dogs aren't able to easily digest. These coatings can also restrict proper absorption which may lead the pill to pass through the system undissolved.
Plus, aspirin of any kind isn't FDA-approved as a veterinary medication, and there's a lack of research about safe dosages and effective use. Your vet's approval is the only thing that should prompt you to use aspirin for your dog's pain, even if you're considering baby aspirin.
Aspirin's key compound, Acetylsalicylic acid, is considered safe for dogs in weight-appropriate dosages. Acetylsalicylic acid is considered an NSAID (nonsteroidal anti-inflammatory drug) that can be prescribed as a medication to support your dog's pain, osteoarthritis, clotting disorders, or musculoskeletal inflammation.
This doesn't mean that it's always safe, though.
Improper use of any aspirin for dogs can lead to serious health issues. Factors such as your dog’s age, weight, health conditions, and any other medications they may be taking all play a critical role in how aspirin affects your dog.
If you're looking for a short answer, there are two primary using aspirin for your dog's pain.
-
The aspirin in your pantry might be too strong for dogs. High doses of aspirin can cause a number of issues with the most significant being damage to major organs.
-
Aspirin often has a coating that dogs can't digest, most commonly enteric. This can cause a strain on their digestive system and internal organs, as enteric-coated aspirin can build up in their system.
Can I Give My Puppy Aspirin for Pain?
This is highly unadvised because the high mg of Acetylsalicylic acid in most aspirin tablets could cause aspirin poisoning in your puppy.
Talk to your veterinarian before giving your puppy any over-the-counter pain relief medicine. They may recommend aspirin, or they may warn you against it. Pain medication comes in many forms and many strengths, so it's important to speak with a veterinarian.
My Dog Ate Aspirin: Now What?
If your dog got into some aspirin, or you gave them some to address their pain, you may need to go to the veterinarian quickly.
How Much Aspirin Can Dogs Consume?
If your dog eats less than 22 milligrams of aspirin for each pound they weigh, they might have some mild problems like vomiting or diarrhea. But if they eat more than 45 milligrams for each pound, it could be serious, even deadly.
Your dog's size matters in this situation. Smaller dogs are more vulnerable.
What to Do If Your Dog Has Eaten Aspirin
- How much aspirin did they eat? Check the mg per pill on the bottle. Most aspirin tablets are either 81 mg or 325 mg.
- Check below to see if action is needed.
Dogs 20 Pounds or Less
Aspirin Dosage | Toxicity Risk |
---|---|
1 pill (81 mg) | High Risk |
1/4 pill (325 mg) | High Risk |
Dogs 20 to 50 Pounds
Aspirin Dose | Toxicity Risk |
---|---|
2 pills (81 mg) | Moderate Risk |
1/2 pill (325 mg) | Moderate Risk |
Dogs 50 to 100 Pounds

Conclusion: Don't Give Your Dog Aspirin.
Don't give your dog aspirin without professional advice. If they consumed aspirin, or other medications designed for human use, you may need to make a visit to an emergency facility.
Under certain circumstances, vets may recommend aspirin to improve your dog's condition. However, you shouldn't use aspirin or any other new medication without your vet's advice.
When you give a dog a product intended for humans, you put them at risk of severe health complications. So, don't give a dog aspirin or any other NSAIDs designed for use in humans!
