please help our super sweet dog named Smokey

I normally wouldn’t do a go fund me but yesterday 8/31/23 our super sweet gentle giant and awesome family member Smokey our dog got hit by a car at 55 mph.The only reason he survived is because he is a 160 lb Great Dane. He sustained abrasions, partial collapsed lung and the most expensive his broken and dislocated leg. I was shocked that the surgery for that would cost 10,000 plus because he needs an orthopedic surgeon. If i cant come up with the money the doctor said the cheapest choice is to amputate the leg. I’m hoping we can save the leg and asking for any kind of help and it will be so greatly appreciated!!
