An Arizona pet-adoption charity accused U-Haul billionaire Joe Shoen’s wife of dumping seven sick dogs on them and then refusing to pay an over $15,000 medical bill — until she was publicly shamed on social media.

Shelly Froehlich, owner of Rotten Rottie Rescue, said she got a call from Sylvia Shoen, the wife of the U-Haul CEO, in May asking her to adopt her six Rottweiler pups and their mom, Coco, because she was battling cancer and couldn’t care for them, according to the Arizona Republic.

Froehlich, 47, felt bad and even waived her usual $600 fee – unaware that Shoen’s hubby is the second-richest man in Arizona and worth nearly $2.7 billion.

But the dogs were very ill – some plagued with genetic disorders, riddled with parasites or ailing from diarrhea and hydration problems, Froehlich said.

Some of the pups didn’t even have their vaccinations, she told the paper.

Treatment for the illnesses, including surgeries, would set the charity back close to over $15,000 and Froehlich, and after finding out who the couple was, asked the billionaires to foot the bill.

“Nobody is going to adopt King Kong with the heavy medical expenses that he will need just to be able to live out his life pain free and happy,” Froehlich said she told Shoen in a text. “I was shocked that a woman of your wealth would have staff that would let these dogs get into the shape that they are in.

The tense situation escalated and Froehlich threatened to tell people how neglected the dogs were if Shoen didn’t pay up.

“This B—h will never see a copper penny!” Shoen allegedly wrote back in an angry text.

So Froehlich took to Facebook to post about the couple, and her account of the incident was shared over 900 times.

Froehlich even shared Shoen’s personal phone number, which had to be disconnected. Some people sided with the billionaire’s wife, saying she’d been through an awful bout of cancer and that it was her hired puppy caretaker who didn’t do their job.

Joe Schoen told the paper he offered to take the dogs back but that Froehlich refused, saying she was concerned about their health.

The businessman, 68, said he was “perplexed” by Froehlich’s decision and claimed his pups had good homes, denying allegations that they had “worms” and other ailments.

“I only wish all people in the world had as nice a place as these dogs,” he said. “They’re hardly in dire straits. These are happy dogs.”

Eventually, he agreed to pay for the medical expenses of two dogs who needed parasite treatment and hip surgery, totaling $15,300.

“I’m happy they finally stepped up,” Froehlich told The Republic.
