If your vet suggests giving your dog aspirin for or something else, make sure it’s coated, so it can dissolve slowly. Stay away from buffered aspirin (which contain antacids) because it’s not safe for dogs. Some companies even make “aspirin for dogs.” However, just because companies make something in fancy flavors doesn’t mean it’s a good purchase. Always remember, aspirin (even baby aspirin) is not without risks. Long term aspirin use can cause ulcers, bleeding, and kidney and liver issues.
