how much aspirin can you give a dog
Ablestock.com/AbleStock.com/Getty Images. The recommended dosage of aspirin for dogs varies from 5 to 15 mg per pound once every 12 hours. To minimize the potential for side effects, start on the low side of the scale. Remember, you can always give your dog more aspirin if necessary, up to the recommended dose. Depending on the size of your dog, you may choose to use aspirin specially designed for dogs, baby aspirin (81 mg) or a regular, human-sized aspirin (325 mg). Choose the type of aspirin that is easiest to accurately divide into the appropriate dose.
