pregnant or why not?

Question
thank you joyce for previous answer, but I guess you did not get my other question about the sister yorkie whom I just "tried to get pregnant" "Supposedly" friday she should be 5 weeks pregnant but I don't see much. A little bit of pinker nipples but no more. She eats and acts normal, no bigger belly. She tied twice . Once should be 5 weeks monday Dec. 26, second Dec. 29th. Is it possible she is not pregnant? How can it be? The owner of male (3 lbs) my female 6 lbs, helped with tie. He does this all the time. I saw it myself. Please what can you tell me. Should I start giving vitamins and puppy food? Please help! This is the sister of the one that lost all her puppies. thanks Sara

Answer
Hi Sara

What day in her season did you breed her?   How old is she?

She should have vitamins regardless of if she's pregnant or not for health.  Kibble does not have enough vitamin or calcium in the mix.

Puppy food should only be given after the litter is whelped as, especially with smaller dogs, the pups can grow to big and cause complications in whelp.
