National Canine Lymphoma Awareness Day

National Canine Lymphoma Awareness Day is observed every year on November 7. It is a day dedicated to raising awareness about lymphoma, one of the most common cancers in dogs. The observance encourages pet owners to learn the signs of the disease, seek early veterinary care, and support research that gives dogs a better chance at recovery.

History of National Canine Lymphoma Awareness Day

The day was established to bring attention to the fact that lymphoma is one of the most common cancers affecting dogs. It honors the story of Terry Simons, an agility dog trainer whose dog, Reveille, was diagnosed with canine lymphoma in 2011 and later passed away. In response, Terry founded the CLEAR Foundation (Canine Lymphoma Education Awareness and Research) and helped launch the awareness day in 2015.
Since then, the day has served to support education, research and resources for dog owners, veterinarians and rescue organisations dealing with canine lymphoma.

Why is National Canine Lymphoma Awareness Day important?

Cancer in dogs is a serious concern, and lymphoma in particular represents a significant portion of canine cancers. For example, untreated dogs with certain types of lymphoma may survive only weeks after diagnosis. Raising awareness encourages early detection, monitoring, and better outcomes for companion animals.
The day reminds us that dogs are cherished family members. Being proactive about their health—regular checkups, recognizing symptoms, seeking veterinary advice—shows our commitment to their well-being. It also strengthens the human-animal bond by bringing education, support, and hope into what can be a difficult diagnosis.
Here are some quick reasons why this day matters:

• It highlights that lymphoma is among the most common cancers in dogs.
• It shares information about symptoms and what owners should look for.
• It helps connect pet owners with research and veterinary resources (for example, through the CLEAR Foundation).
• It encourages regular veterinary checkups and vigilance for signs of illness.
• It fosters community support for dog owners whose pets receive a lymphoma diagnosis.

How to Celebrate (or Observe) National Canine Lymphoma Awareness Day

Observing this day can be both practical and meaningful. Start by educating yourself and others: learn about what lymphoma is, how it shows up in dogs, and what treatment options exist. Many veterinary clinics, animal hospitals and rescue groups join in the awareness effort.
Also consider taking action: schedule a wellness check for your dog, donate to organisations supporting canine cancer research, or share social-media posts and stories to help spread awareness. These activities honour dogs currently undergoing treatment and remember those who have passed.
Here are ways you might observe the day:

• Visit your dog’s veterinarian for a wellness screening or ask about lymph node checks.
• Post on social media about canine lymphoma awareness to help spread knowledge.
• Make a donation or volunteer with organisations focused on dog cancer research.
• Share resources (articles, videos) about canine lymphoma with other pet owners.
• Spend extra quality time with your dog—reminding both of you of the bond and the importance of health.
