Save amara, help my baby Pooch (name coincidence)

This last year has been hard for many people, it has been especially hard on us, due to a broken system and a pregnancy, I have been unable to collect unemployment, no pandemic assistance, I did not receive the stimulus, I was told I can’t file taxes since I had no income. We adopted an abandoned puppy who is nothing but a love bug, when I was pregnant on a walk this took an innocent spill down a hill, turn out it was not so innocent. A stick penetrated through and through her leg, from the back into her inner thigh, to the stomach; we were a mile out on the trail. I was 37 weeks pregnant. Amara could not walk back on her own she had to be carried and rushed to a ER. I went into early labor my son and as born small. Struggles to this day with sleep and reflux: at the time my momma instinct kicked in I thought I was doing what was best.  I walked so fast carrying a dog 37 weeks pregnant and pushed my body I started having contractions and I rushed and walked faster probably faster than any pregnant woman in history. I did what I had to, in order to keep her safe and alive I went into early labor and ended up myself in the hospital resulting in various other medical expenses and then weeks of bed red rest. At first I took her to Piper Olsen who made us wait in the car for 4 hours while taking other patients. Finally I took her to Central emergency and they were able to bring her in and operate immediately. That visit ended up being $8,987. The stick and fall we have found out caused long term and permanent damage. Since Amara was so young I had not yet got pet insurance for her and since she has history she is unsurable. Amara now needs her hip fixed and her knee repaired now that she has healed from infection and had time to cope with her previous trauma. These two surgeries cost roughly $15,000. One is a TPLO for CCL repair. I am unsure what the hip surgery is called but I guess the ball and socket joint that is her hip, her ball is not in her socket from the fall, which is why she can’t use the leg.
I am asking not for all of it. I have a credit limit of $2000 that I can put towards it. I feel horrible. I really want to not have to put down a year and half old puppy. She is so young and the doctor says once the surgery is done she should heal fine and live a long, normal healthy life. I just want what is best for her. She already had a such a rough start I want to give her a long happy rest of her life. I cannot bring myself to put her down. I just can’t. She is so good with my son. She protects him, plays with him, sleeps with him and keeps him entertained. It would be a Gravis loss if I can’t save her. Thank you in advance everyone for your help and support with this. I just don’t have this kind of money. Heck since being out of work with COVID I haven’t even bought clothes for myself post baby. I haven’t even gotten new undies everything I have goes to my son and my son loves this dog so I feel I have to do everything in my power to save her.
