My heart aches for you, and I searched for some way I could help--so many good suggestions, so many prayers and hearts are with you and Cookie tonight. The only new things I can add are two links. One is from this forum:
http://www.yorkietalk.com/forums/gen...st-yorkie.html
And the other is a service I found online:
https://www.findtoto.com/pet-alert-service.html
I can't vouch for the above service and am not affiliated with them. I just did a search online and found them.
Remember that you are not alone, and Cookie is not alone. So many hearts and prayers are with you that I believe there will be a positive result.
Bless you and your baby.
