Please Help Our Lil Gunner

Hi, my name is Lucrezia Weyland and I'm not usually the person to ask for any kind of help especially financial help. This past Sunday Gunner got out of the house and got hit by a car, thankfully he is still alive and all his organs are in good condition. Unfortunately the sacrum/coccyx bone is fractured and he will need to see if any nerve damage has been done so we were told he needs to see and neurologist and get an Mri and also have to have his bone repaired. We are only estimating $4,000 because all we know the MRI is $2,000, we do not know what surgery would be or a visit would cost. If can help even just a little bit it is much appreciated. Thanks for your help.
