How do I know if my Yorkie is pregnant? She has shown some of the signs. She's been sleeping more, possessive with her toys, wants more attention, swollen nipples, and swollen abdominal for the first 34 days. At her 35th day, her abdominal area has shrunk considerably, but everything else has stayed consistent.
Is this normal or is it possible that she was never pregnant and was just showing the signs?
Any suggestions will be appreciated.
