How much aspirin for a 20 lb dog?

For a 20-pound dog, the general guideline for aspirin dosage is approximately 5 to 10 mg per pound of body weight every 12 hours. This means a 20-pound dog could receive between 100 mg and 200 mg of aspirin per dose. However, it is crucial to consult a veterinarian before administering aspirin, as they can provide the appropriate dosage and ensure it is safe for your dog's specific health conditions. Always monitor your dog for any adverse reactions when giving medication.
