Cheems Balltze has died at 12 after a battle with cancer.

The Shiba Inu, also known as Ball Ball, died last week after a thoracentesis surgery. The dog fell asleep during the surgery and never woke up.

The owner of the Cheems shared the sad news to Instagram.

"Ball Ball fell asleep on 18/8," his owner told his 800,000+ Instagram followers. "He fell asleep on Friday morning during his last thoracentesis surgery. Originally, we wanted to arrange chemotherapy or other possible treatment for him after this operation, but it is too late now."

"I believe he is running freely in the sky and having a lot of delicious food with his new friends," the owner added. "He will always be inside my heart. I hope he can continue to bring joy to everyone in the online world, that's my only humble request."

Cheems became an internet sensation for his memes centered around his love of cheeseburgers.

Cheems became even more famous after his image was used for two popular memes that you've probably seen a million times before.
