That depends, Katie. While certain veterinarians may prescribe buffered aspirin in low doses for their canine patients, we strongly advise owners to never give their pets any medication without first consulting with their regular veterinarian. Many drugs, including non-steroidal anti-inflammatories like aspirin, can cause serious or potentially life-threatening problems, depending on the dose involved.
If you feel that your dog needs pain relief for any reason, we highly recommend that you get in touch with your veterinarian—if you have not already—so that your dog can be evaluated. You vet can direct you regarding the best dose to use or, if necessary, can prescribe a different pain reliever.
