National Pet Cancer Awareness Month is an annual designation observed in November. Cancer is the leading disease-related cause of death for domestic dogs and cats in the U.S., so this month, spread the word to help educate pet owners about how best to protect their furry family members.


We love our pets just like we love our family, so let’s do our best to keep them healthy. However, cancer in animals continues to increase over the years, but the good news is there are advances being made in healthcare when it comes to early detection and treatment.

Use #PetCancerAwarenessMonth, or #PetCancerAwareness to post on social media. If you have a cat or dog at home, consider scheduling them a medical appointment for a checkup, and keep your eyes open for some warning signs that your pet could have cancer. This month, and in the months to follow, keep your eyes open for any of these signs. If you can catch cancer in your dog or cat early enough, you just might be able to save them.


National Pet Cancer Awareness Month started in 2005 and was created by Nationwide and the Animal Cancer Foundation with a goal in mind to raise money and increase awareness to fight the leading killer of pets.
