HELP THE VETS

My dad did 18 years I'm the service, sacrificed time with his children,wife,family and life and gets gets barely any help with medical, etc... He had a heart attack less then a month ago and his last checkup when he was still having problems was told to go to the ER but cant be guaranteed that they will cover it. Are you kidding me my dad deserves more then the best care ever him along with every other vet. Please help me for our vet not only with medical care but housing and every other thing they deserve thank you.
