Rehoming the love of my life.

I am so depressed about this. Anyway, there's been a domestic situation and for my dogs safety I have to rehome/foster her while I look for a new place. I am currently in a shelter with my newborn. My border collie/aust. Shep mix is my world. She was my first baby. Her sister, who I took in 3 years ago (my friend passed, I couldn't let her sit in a shelter), they're best friends. This is my family.

I've called the resources in my area (NY, USA) even the crisis center. (They have a program called PAWS for Safety) they don't have any solutions for me.

Is there a site, subreddit. Somewhere..I can find someone to foster (I can pay for their food, they shouldn't be need to be seen by the vet but if need be I'm sure I can cover that as well. They're healthy girls) Can someone refer me to a place? It's been almost a week without them, the apartment I may have found it will take a few weeks for me to get in, if I get it. I want my girls safe and happy and to come back to mommy.

I'm panicking, if not, my abuser is threatening to get rid of them. I'm not in the home, I have no idea what they are.going through. Can someone please help and post some links, popular sites or things (I haven't found any) where pet parents help others? I am desperate for my girls.
