Aspirin is usually the first drug of choice for pain relief in dogs, especially if the pain originates from arthritis or joint damage. Aspirin is a non-steroidal anti-inflammatory drug (NSAID) and shouldn't be combined with other NSAIDs.
Aspirin comes buffered or with an enteric coating. Always buy buffered aspirin because your dog can't metabolise the enteric coating, which could cause an overdose.
You can give your dog a low-dose 81 milligram aspirin, or you can calculate 10 milligrams per 1 pound of body weight, given every 12 hours.
As a non-steroidal anti-inflammatory drug (NSAID), aspirin reduces inflammation and blocks some pain receptors.
Long-term use of any NSAID, including aspirin, can cause stomach ulcers, gastric bleeding, diarrhoea, vomiting and liver and kidney damage.
You can purchase low-dose dog aspirin at your vet or a pet store, but you can also use the children's or low-dose adult aspirin sold in drugstores.
