Please help Marley get her life saving surgery

I've created a bank account for those that dont want to put it into here Account name: marley Bsb: 923100 Account number : 44114994 I never ask for help but I'm desperate to save my little girl.  On the 15th November I was driving on our farm and my 4 dogs are always by my side. Macey and Max are the parents of Marley and brother Benson.  Mars and Benson are 21 weeks old. I am always super careful when I'm in my car, checking and double checking nipping my horse to make sure none of the dogs are under or in front of the car.  I checked and didn't see anyone. Put my car into first gear and slowly rolled off.. But then I heard the scream..... I stopped and opened my car door and screamed at the sight of little marley underneath my back wheel. I reversed off her and ran to her. She was screaming with pain. I was screaming and crying and in total shock.  I picked her up and put her in the car and took her straight to the Lort Smith Animal hospital   I rang ahead and let them know I was bringing her in. So when we got there I rushed her in and they put her on a stretcher and took her off to administer pain relief. I was fearing the worst outcome but didn't know anything till the xrays were done. They took bloods to make sure she had no internal bleeding and I had to wait till the next day for the xray results. Marley isn't in a good way, she has broken the greater trochanter off her femur and the bone has completely moved. She has fractures on both hips .  Some may ask why I won't put her down and I have thought about that. But they seem to think that once she's had the hip replacement she will have a good quality of life. Shes only a baby and has so much more time on her hands.  The first operation is to pin the femur back together. This operation is approx $4000. My current vet bill is $1000. For them to do the surgery I need to find a $1500 deposit. If the surgery is a success she'll need rehab which I have no idea of those costs.  In 12 months time when she's matured she will need a double hip replacement and then she should be back to near normal again.  Hip replacement is approx $6000 per hip. Its absolutely insane but I owe it to her to keep alive and get the best outcome. I feel horrible even doing one of these but so many people have suggested I do one to save little Marley.  So I thank you in advance. My 6yo son is devestated and keeps asking how we're going to raise  the money for her. I've created a bank account Account name: marley Bsb: 923100 Account number : 44114994
