Pregnant Husky Needs Surgery

Thank you for taking the time to read this. My name is Vi. I'm a hard working dog mom in a tough financial situation. My Husky Jaxx was in an accident. She lives/guards in a warehouse filled with metal, wood, tools and cars. Last night when she went out to go potty, a large metal pipe (150lbs) fell on her left paw. She screamed so loud and ran in circles. I felt terrible and cried all night. She now has three fractures and needs a very expensive surgery to fix it. To top it off she's pregnant! It's been hard because she had some tummy issues a week ago and had to go on special food/meds. That alone was 200$. I rescued Jaxx as a stray. She is a little over a year old. Few weeks later she went into heat and ran off. I wanted to get her fixed but it hasn't been going well financially. I know our city offers free spay/neutering but for her size and being female, I've researched and found it to be risky since those facilities aren't as clean etc. I was saving up to get her fixed and then she had tummy issues $200 (1weekago). After that my second dog Auto (Also a rescue stray he's almost 3yrs old) had a bill of $240 (a day ago) for an ear infection and skin burns on his paws. Today we did X-rays, meds and she now has a splint total today $200. There go all my savings. I was going to use it to spay her, but now she's having puppies. I'm in a tough situation and would like to help her have her babies safely. She needs surgery before her injury heals wrong. I appreciate you reading this. If you could help or know anyone who could help us we would be forever grateful.
