PS-Jill is so getting an AT HOME DOG SITTER from now on........I used to have one..but she went away to college...sigh...
What a tragic story! I'm so sorry for you and Einstein. Of course you must be beside yourself.
I don't know if this would work for you, but we asked our vet if any of the technicians that work there would be interested in pet sitting. (We love our vet and knew they only hired the best of the best staff.) It turned out to be a wonderful solution.
Good luck to you and your family. Vacations aren't meant to be this way.
