You'd be surprised, a male dog can smella female dog in heat for MILES. Another dog could hop the fence into your yard & mate with her. Male dogs will go to extremes to get to a female dog in heat, they will bite & chew through things, jump over things, they do what ever they can to get her. I would NEVER EVER leave an in heat female dog alone where there is even the slightest chance of her getting pregnant.
