Help Dior be more comfortable

Help! Our baby Dior got hit by a car and needs a surgery we can’t afford. She’s got many injuries but the one that needs surgery is a very bad break on her humerus. The surgery is over $4,000 just to repair her humerus bone.  With all the vet bills we have gotten we can’t afford that at this time.  We just want to make her comfortable.  So we are going to get her leg amputated.  We could use any help we can get to help cover the cost of her surgery.
