Hi everyone!
My fears were in vain. As far as the vets can tell she is not pregnant! Just gaining lots of weight from the good food she is finally on. She got an ultra-sound and the think they found a kidney stone though

Here is the good news! At the same time I took in my 5lb. yorkie and she is pregnant! (planned breeding). They did x-rays and an ultrasound and they saw 3 and possibly 4 little munchkins playing in there. She has about 2-2 1/2 weeks to go

Thank-you all! And I will keep you updated on Lillie's puppies.
