Celebrated on 11/01/2026
Did you know that approximately 1 in 4 dogs will develop cancer at some point in their lifetime, and for dogs over the age of 10, that number rises to nearly 50%? National Pet Cancer Awareness Month was established to educate pet owners about early detection and treatment options, potentially saving countless animal lives.
National Pet Cancer Awareness Month was established in 2005 by the Veterinary Cancer Society (VCS) and the Animal Cancer Foundation (ACF). The initiative aimed to raise public awareness about the prevalence of cancer in pets and to promote early detection and treatment. The month of May was chosen to coincide with National Pet Month in the United States, leveraging existing pet-focused campaigns to maximize reach.
Since its inception, National Pet Cancer Awareness Month has grown significantly, with veterinary clinics, animal hospitals, and pet organizations hosting educational events, fundraising walks, and screening clinics. The rise of social media has amplified the campaign, using hashtags like #PetCancerAwareness to share stories and resources. Today, many veterinary practices offer discounted cancer screenings during May, and pet insurance companies often highlight cancer coverage options. The month also serves as a platform for research fundraising, with events like the "Paws for a Cure" walk.
