What is Aspirin?

Aspirin is a very common over-the-counter pain medication for humans that fall within the category of a Nonsteroidal anti-inflammatory drug (NSAID).

Prostaglandin is the main compound that is responsible for causing fever, inflammation, and pain. The active ingredient in Aspirin blocks prostaglandin production in the human body, thereby reducing pain and inflammation.

    Keep in mind that if your dog is injured, just relieving them of the pain is not only the objective here. The aim should be healing them. Giving them aspirin in these cases is not the best solution as Aspirin will reduce the healing ability of your dog. 

    For healing from any injury, a dog requires prostaglandins, and aspirin pauses the production. This lipid-like hormone is part of a dog’s natural healing process. Also, giving a dog aspirin for a long period has a tendency of joint issues for your dog.

    Alternatives for aspirin

    It is obvious, that your vet would know the best and have a good reason for prescribing aspirin to your dog.

Carprofen is a medicine that is often prescribed for the treatment of osteoarthritis, and it has been seen that it is better for dogs than aspirin does.

    But if your vet has not recommended any such alternative, it is best not to interfere in between and take charge of it on your own. There are various human drugs that do not suit dogs well, and might have a negative reaction on them. You might think that it will be better for them, but instead it might harm them in a certain way, that is beyond your knowledge.

    Instead of going through all this difficulties, take a little bit of time and have a detailed knowledge about aspirin, and could help your dog in the near future. Just give them the proper dosage that has been prescribed by your vet, and keep an eye for any side effects. And for any query consult your vet immediately.
