Help Save Tyrion

I am heartbroken. How do I tell Evan there's nothing I can do? This dog is his best friend and therapeutic in so many ways. After every hospitalization he rushes to greet him. Tyrion was rushed to the vet for a bowel obstruction. Unfortunately, the cost of surgery is more than we have and Care Credit is not an option. We are left with no other choice than to take him home to die.
This little boy was born with a rare medical condition called Prune Belly Syndrome.  He has had 6 hospitalizations since he started school in September.  My husband is currently deployed so we have taken a hit in our budget.  This dog is such a special part of our family. This is time sensitive since his bowel may be dying.  Any contribution would be greatly appreciated.
