Can a pregnant dog go outside with other animals including dogs?

plz ppl don't think this is a stupid question abut i know some breeders and some say i shouldn't let my dog out and others say that i can, i just wanted 2 know what you guys think. she wouldn't be doing any fiscal exercises she would be just gettin out the house she is only 2 1/2weeks pregnant she can no longer get pregnant from other dogs!
