Is your dog injured or suffering from an illness?

You’re probably looking for a pain reliever. One of the many popular pain killer pills used is aspirin. The thing is- Is it safe for your dog and cat?

What is Aspirin For Dogs?

Seeing your dogs in pain is the hardest thing. Whether it is from a post-surgery pain or sore paw, it is hard to see them suffer in any way. Addressing the root cause is the best solution to make the pain go away. But, sometimes giving them aspirin is the best course of action.

Aspirin is an over-the-counter drug for pain relief. It is actually formulated for people, but surprisingly it is safe for dogs as well. It is considered to be the best among OTC drugs as it is nonsteroidal and anti-inflammatory. It also prevents blood from clotting.


In general, it has fewer side effects than other pain relievers. Given the following good points, you might be tempted to administer it right away when your dog is in pain. However, it is still a drug that has to be taken with caution.


Seek advice from a licensed veterinarian. Proper guidance can prevent toxicity, which could happen from overdose.

Ingredients in Aspirin for Dogs

All aspirin has acetylsalicylic acid as the key active ingredient. Some pet brands do have added flavorings though. Certain manufacturers have developed coated tablets with powdered cellulose, corn starch, and triacetin.

But, there’s no need to worry! Those are inactive ingredients that would not cause any negative reactions.

Some may still not consider giving their canine companions aspirin, especially with the harmful side effects associated with the drug. But, are there any alternatives? Well, these days, natural alternatives aren’t hard to find.

Aspirin Alternatives

Natural food supplements are always great alternatives to medicinal drugs. Here is a quick rundown of these natural substitutes that possess anti-inflammatory properties:

Fish oil

It is a great choice for arthritis, bowel diseases, and allergies. It relieves pain while helping the kidney detoxify itself, unlike aspirin that leads to kidney damage with prolonged usage.

Extra-virgin coconut oil

Aside from its anti-bacterial and anti-fungal properties, it can also reduce inflammation and pain. Unlike aspirin, EVCO can also be used to treat skin infections and maintain a shiny coat.

Herbs and spices

Rosemary, turmeric, and ginger are known to reduce inflammation. What makes them superior to aspirin, however, is that they are rich in anti-oxidants such as polyphenols and bioflavonoids.




Blueberries and blackberries are great choices. They not only taste good, but they are also rich in vitamins, flavonoids, and carotenoids.

Dark leafy vegetables


Vegetables are rich in essential nutrients for your dog’s speedy recovery. Not to mention, the anti-inflammatory and detoxifying properties they have are among the best.

These are great alternatives to aspirin, especially with the additional nutrients they provide. The only downside of these options is that their effect may not be as fast as aspirin’s. Fortunately, there’s a substitute that can compare when it comes to potency:

CBD oil

CBD oil is considered to be the modern choice of today’s pet parent. CBD is naturally derived from hemp. There are numerous studies that show its beneficial effects.


It is used as a supplement, as well as for treatment and preventive care of dogs. It is used around the world for its pain-relieving and anti-inflammatory benefits. It positively affects appetite, sleeping patterns, mood/mental states, and cardiovascular health. It even boosts the canine immune system.

CBD is great for dogs suffering from chronic joint pains due to old age. It supports healthy bone and joint function, as well as helps with muscle stiffness and soreness. It is also known to have muscle relaxant properties.

Dogs in their golden years lose their vitality and may seem down and sad all the time. CBD oil can lift up their mood with its mood enhancing effects.

CBD oil still has side effects though, but not as harmful as those of aspirin. Possible side effects include dry mouth, low blood pressure, and drowsiness. Compared to other natural alternatives like fish oil, results can be seen within a few minutes of administering CBD.
