Is She?? Is She Not???

It's so difficult to tell if my Downsy is going to have pups of her own. It's been three weeks since she was bred to the handsome Beau and although there are some signs, I won't be able to say definitely until at least 4 weeks have passed. She is losing her appetite right now and that is sometimes a sign of pregnancy but not always. She is slightly enlarged in the teats but again not always a sign of pregnancy. Only time or an ultrasound will tell and we can't do an ultrasound until at least 30 days have passed since the last breeding.
