And there again come the dogs with their endless diseases…
A 11,000 year old cancer still alive today, all thanks to dogs:
First described in 1810, Canine Transmissible Venereal Tumor (CTVT), was first thought to simply be a form of canine cancer.
By 1871, scientists realized the cancerous tumors were infections, spread by sexual contact. Today, CTVT is found across the globe, although, interestingly, recent research has demonstrated that the cancers have a remarkable relationship:
The DNA in one tumor is very similar to the DNA in other tumors – even tumors growing in dogs on the other side of the world.
But How Dog Cancer Becomes Contagious, on Humans?
Here is how:
Eleven thousand years ago, one saucy canine got busy and, as can happen with unprotected sex, gave its partner a venereal disease, although uniquely, this VD was cancerous. Over the course of the intervening millennia, that second dog, its partners, and its partners’ partners, all did what dogs eventually do, each spreading the disease, which has continued to retain some DNA from its progenitor.
Now doggists have NO way to deny that dogs DO cause cancer. On humans.
And they might refrain from their bestialities practices of getting into a “love affair” with their “safe” furry friends.
