Is Aspirin Poisonous to Dogs?

In the right dosage, aspirin can benefit a dog needing pain management. However, as with many over-the-counter medicines, dogs (like people) can overdose on aspirin with severe, possibly life-threatening, consequences.

  1. What Aspirin Is Used For

    • Veterinarians sometimes prescribe aspirin to treat pain and inflammation in dogs.

    Dosage

    • The recommended dosage is 5 to 10 milligrams (mg) per pound of your dog's weight. Baby aspirin is sold in 80 mg amounts, and regular-strength aspirin for adults is generally 320 mg. Some pet stores sell aspirin in smaller amounts suitable for dogs; consult with your veterinarian for recommendations.

    Symptoms of Toxicity

    • Symptoms of toxicity include heavy panting, vomiting, lethargy, loss of appetite or extreme thirst. Call your vet if your pet exhibits these symptoms and you suspect aspirin poisoning.

    Preventive Measures

    • Your dog is like a child. Keep medicines in a dog-proof container.

    Considerations

    • Give your dog aspirin only under the direction of your vet. Follow the dosage specifications closely. Do not give coated aspirin to dogs, as their bodies cannot break down the coating. Never give aspirin to puppies--their bodies cannot process aspirin at all.
