Help Ruger walk again

Please help our 2 year old mastiff!  Our sweet boy was seriously injured last night (8/19/2020) while playing in our backyard.   We rushed him to the emergency vet, where they quickly realized he had snapped his humerus in half.  Ruger was stabilized, and we rushed him down to Purdue University.   Today, (8/20/20202) has been very emotional as we have tried to figure out the best plan to help our four legged family member.  Surgery is scheduled for tomorrow morning.  We have put our faith in his surgical team.  Nobody is fully prepared to hear the words orthopedic surgeon, amputation,o worst we may not be able to help him, but he is our big teddy bear and we want to give him every fighting chance!  Ruger and our family thank you for any help!  If all of this works I am sure he would love to give you big sloppy mastiff kisses!
