my yorkie arent showing any signs

Question
my yorkie went into heat on dec 7th..i brought her to the breeder on the 11th..which was just for days after she started bleeding. i dont know if this is normal but she held my girl down and let the smaller yorkie have her way with her.. i didnt think she was ready but since she was the breeder i let her do what she thought was best. we did that 3 more consecutive times one day apart..its been two weeks since she last mated.. and she still isnt showing any signs of being pregnant..ie teats getting bigger, swollen vulva getting larger..anyways i just want to know if theres a possibility she didnt get pregnant, which is totally fine..i just want to know what are her chances..thanks in advance for your help

Answer
Hi Rye

Your "breeder" should know better.  If day 1 was the 7th, that would make the 11th day 4.  A female isn't ready until at least day 10, unless you know for certain that she ovulates early.

It's too soon to say for certain, you'll just have to wait and see.
