McDaniel said McGuire told her: "You take that dog to any vet you want, and I will pay for every penny."
At first, McDaniel couldn't imagine accepting money from a total stranger.
But McGuire insisted.
"I said, 'Don't worry about it. I'll pay for it.' And she said, 'Are you serious?'" McGuire recalled later that day. "You just don't say no when someone's world is collapsing. If you have a way to help out, you help out."
McDaniel gathered up Gabanna and hurried to drop off her daughter with a baby sitter.
On her way to the veterinarian's office, McDaniel realized her gas tank was nearly empty. She stopped at a nearby Rutter's to fill up — only to discover she had left her wallet in the diaper bag she left with the babysitter.
Panicked, McDaniel went into the store and called her fiancé for help. An assistant manager at the store tapped her on the shoulder.
"She put $10 in my gas tank out of her personal pocket money," McDaniel said.
And off they went to get Gabanna the medical help she needed.
Gabanna suffered a broken pelvis, and her skin is badly scraped. But, McDaniel said, she is expected to make a full recovery.
For the next couple of months, McDaniel will be keeping Gabanna as still as possible. Hopefully, the canine escape artist won't need surgery.
And the $470 veterinarian bill will be covered by a 31-year-old CEO and some of his Facebook friends who offered to pitch in when McGuire posted this story online.
"Honestly, my fiancé and I haven't really met people like this before," McDaniel said. "It's just nice to know that people still are like that."
