Well, if she is pregnant, then puppies are due in a week more or less. Who cares about registration papers with mutt puppies?
All bets are off when you have a bitch in heat. You cannot expect a bitch in standing heat to stay in her yard, especially a puppy. You flunked this test. The chances are overwhelmingly in favor of your bitch being pregnant. It could be a false pregnancy, but she is young and probably fertile, most likely there is no reason for it not to have taken.
Two choices now are spay/abort or have the litter and find homes for a bunch of shepherdoodles. At a year old, your bitch is likely full grown, she is young but probably strong enough to have the puppies. Shepherd pups are normally long and skinny so there may not be any complications -- don't count on this, get a book so that you can recognize the signs of trouble and get help if you need it. Youngsters sometimes are not ready to have puppies, so great care is needed for the first few days to ensure that she is fully taking on her role. Plan to take a week off of work if you are working.
