It has been 23 days since my yorkie was bred. I am wondering if some yorkies just don't show very much? On day 20 she did throw up. I think she may have had morning sickness? I am very anxious to find out and am looking for signs of it. I will not take her into the vet until next week. By then the vet should be able to feel for any puppies. Waiting is the hardest part!
