Does Kabosu have leukemia?

Could you please clarify for me if there's any truth to the rumor that Kabosu, the famous Doge meme dog, has been diagnosed with leukemia? I've seen some posts online that mention this, but I'm not sure if they're accurate. I'm genuinely concerned for the well-being of this beloved internet icon and would appreciate any reliable information you may have on the matter. Thank you in advance for your help.
