I live in the country where there are coyotes. I do not know what spaying or neutering has to do with that. Please explain.

It is natural, but it does not happen in a vaccume. If you have an intact bitch and an intact dog and leave them together unsupervised, yes you are likely to have a litter. If you are right there, like in a dog park, there should be no trouble recognizing what is going on in plenty of time.
