Aspirin is the go-to medicine for any pain. But is it safe for your dogs and just how much are you allowed to give to them?

What's Aspirin

Having knowledge of whether aspirin is safe for your dogs and the dosage allowed is very helpful especially at times when your dog is suddenly in pain. You might already have a bottle of aspirin in your bathroom drawer and have considered sharing the medication with your dog. But before you give any medication to your pet read on to see what are the effects of aspirin on your dog.


Aspirin is a nonsteroidal anti-inflammatory medicine like ibuprofen, naproxen, carprofen, and other pain killers. Nonsteroidal anti-inflammatory drugs (NSAID) are used for pain, fever, and inflammation. Aspirin is also an anti-coagulant which makes it a very useful medicine. Most homes have a bottle on hand already. But just like in humans there are dogs who might have an allergic reaction to certain medications such as aspirin.

Although it is widely used as an instant pain reliever, most NSAIDs can cause unwanted side effects. It is best to consult your vet on which NSAIDs are appropriate for your dog. They will prescribe an effective and safe aspirin to relieve the inflammation and pain of your dog.


Most aspirin is safe for both humans and dogs, but allergies and some unwanted symptoms might arise if you have not yet consulted your vet. It is important to be aware of these risk factors and side effects before giving your dog aspirin. Be sure to observe your dog after giving him aspirin to make sure that there are no changes in his behavior. If you notice any of these symptoms it is important to immediately go to your vet to eliminate the possibility of aspirin poisoning.

Your vet will give you the right dosage of aspirin for your dog. There are several factors to consider for the right amount of aspirin such as age, body weight, and health condition. A typical dosage guideline is 5-10mg per pound of your dog’s weight. Dosage is given every 12 hours. Make sure your dog has eaten to prevent stomach irritation. Some dogs will find it hard to digest coated aspirin and your vet might give you an alternative medicine instead.

Always ask your vet for the right medication and dosage for your dog. Every dog is different and will require different types of treatment and medicine. A proper assessment at the veterinary clinic is needed before putting your dog on any medication, and it’s important to ask your vet all the questions, rather than trying to guess what’s best for your dog.

If a certain brand of aspirin or dosage is not always available to you and your dog, ask your vet for possible alternatives before giving your dog medication in case of emergency situations.
