It can also reduce fevers and can reduce a chemical that is important in the effectiveness of platelets. This results in platelets losing their ability to clump together to prevent bleeding.

Therefore, stomach irritation cannot always be prevented by giving the drug with food or by using a “buffered” or coated aspirin tablet.
Aspirin may interact with other medications and should never be used with other non-steroidal anti-inflammatory drugs (such as Rimadyl, Novox, Meloxicam, Deramaxx and many more) and steroids (such as Prednisone).
To be safest, never administer aspirin to your dog without consulting your veterinarian because there are many drug interactions and side effects.
