I always take medical advice from trucks that cannot spell cancer or nose, and don't know the difference between prevent and pervert. Strangely they did use than, instead of then, but it's probably a typo.
Still, America needs more trucks to disseminate vital medical knowledge.
Biden has a dog. Just sayin
So, its not as unhinged as it sounds. Still very wrong mind you. But transmissible cancers are a thing, they just tend to be intra-species, and there isn't such a cancer for humans excluding things like organ transplants. This type of cancer does exist in dogs. Generally its called Clonally transmissible cancer, which given this persons spelling, is likely how he ended up at colon.
I don't know about the cancer stuff, but I'm definitely with him on the No Dogs In House part. No dogs allowed in my house.
No I'm pretty sure he's talking about pervert cancer look how much attention he pays to what dogs do with their noses and butt cancer cells
