My little foster dog is still pregnant! I took her to my own vet and after a thorough examination, ultrasound, x-rays decided she was only due early this coming week! When I told her owner she admitted a mating could have happened quite a few days later than she thought

But I'm a lot more relaxed and confident with my vet now looking after her. He and I have successfully been through many pregnancies and I trust him.
But my problem now is she's getting so picky about food, has such a small appetite and won't eat any dog food! This is really frustrating me because of her earlier poor nutrition. I really want to make sure she gets the best possible now to make up, but she's not making it easy for me

Any suggestions? I've been lucky that mine have always been happy with mostly a good quality dog food so haven't had to deal with this before.
