Dumped pregnant tiny yorkie

A dumped very pregnant tiny yorkie . She is young but was carelessly left unattended when in heat The male was a larger chihuahua mix over 3 times her size. She may need a c-section, also has hair loss. She needs full vetting. We have named her little Mia. She is very scared. Please help me get Little Mia all taken care of. I have been rescuing for 5 yrs & never came across anything like it. She cant even move. We r going to vet in the afternoon. I have other rescues looking for homes & some still need fixing.

Please help in any way u can
Thank You & God Blessed all you Angels
