Maybe it did work out in the dog's best interest. But it wasn't without Frank getting on his flight knowing the dog was tied in the back of the truck, where it remained for FIVE DAYS. So it just as easily could have been a slow death for the dog. Did you read Frank's assessment of his mother's pet? "It’s an old dog – no one wants a 6 1/2, 7-year-old dog with a goofy hip.”Which may have worked out for the dog.
He knew the risk he was running by abandoning that animal at the airport. That's low.
He says he called every shelter within 200 miles, but did he really? We can't be certain. I wonder if every ASPCA/Human Society location really did turn him away.
