The Origin of National Canine Lymphoma Awareness Day

Her name was Reveille, and like her moniker (which translates from French as “wake up”) the legacy of the dog agility competitor who lost her battle with canine lymphoma in 2012 continues to awaken awareness in animal lovers about this common form of canine cancer.

Observed each year on November 7, National Canine Lymphoma Awareness Day was established in her memory by Reveille’s favorite person, dog agility trainer and competitor Terry Simons. During the year that Reveille lived with the disease Simons went in search of information regarding treatments that might prolong her life. This search put Simons on the path to founding CLEAR (Canine Lymphoma Education Awareness and Research), a non-profit organization which is striving through clinical research to create a better tomorrow for dogs facing a canine lymphoma diagnosis, and offers concerned dog lovers both a better understanding of the disease their dog is fighting, and the choices available to help their furry family member.
