under dogs
so theres this new contagious cancer in dogs wich started from a single cell and had a transmission from one dog to another. in a lab they created a contagious cancer and tested it on mice and within a few days it spread. this is so scary everything evolves even diseases and i feel like this is its next step in cancer where it will be transmittable. also tasmanian devils are becoming extinct because of a contagious tumer cancer. yikes
