What are teats in male dogs?

Teats are In male dogs for absolutely no reason so why don't you call a vet for that

(new person writing) No need to call a vet. Human males also have teats on their chest, and can even get breast cancer. The difference is that human females have permanently enlarged breasts, whereas unless a female dog is nursing, they have flat breasts--like male dogs, male humans and (so far as I know) all other male mammals as well.
