Asprin is not great for dogs however it is the ONLY over the counter pain med reccomend, (accutally baby aspirn) on a full stomach, and only if really needed. Its hard on the liver and kidneys, but most of the animal anti-inflamitorys are thats why animals require a blood test to be on them for longer periods of time. Not sure of the dosage, Id go to a vet and not take any chances
Advil and Tylenol are big NO NO's!!!!!
