Richest Dogs in History: 5 Pets Who Inherited Millions (and How Pet Trusts Work)

Imagine finding out your dog is worth more than you. We've all joked about our dogs living better lives than we do. They sleep 18 hours a day. They eat gourmet treats. They have orthopedic memory foam beds. Some even have birthday parties.

But what if your dog also had a multi-million-dollar inheritance? Believe it or not, several dogs throughout history have become richer than many doctors, lawyers, and CEOs after their owners left them enormous fortunes.

Before you start wondering how to convince your Labrador to add you to his will, let's meet five of the wealthiest pups the world has ever known.

1. Gunther VI – The Dog Worth Hundreds of Millions

No list would be complete without Gunther, perhaps the world's most famous wealthy dog. The story began in 1992 when German Countess Karlotta Liebenstein reportedly left approximately $80 million to her beloved German Shepherd because she had no close heirs.

The money was placed into a trust managed by trustees rather than being owned directly by the dog. Over time, those assets were reportedly invested and grew dramatically. Today, the Gunther trust has been associated with luxury mansions, yachts, sports cars, and other investments. Media reports have often valued the trust at hundreds of millions of dollars, although some aspects of the story have also been described as part marketing and part legend.

Favorite luxuries: Italian villas, exotic cars, private staff, and gourmet meals. Talk about living the "ruff" life.

2. Trouble – Leona Helmsley's Tiny Dog With a Huge Bank Account

Hotel billionaire Leona Helmsley, often nicknamed the "Queen of Mean," shocked her family in 2007 when she left $12 million to her Maltese named Trouble. Several family members challenged the will, and a judge later reduced the inheritance to $2 million — reasoning that was still more than enough to provide excellent care for the dog.

Even with the reduction, Trouble lived a life that included personal security guards, luxury veterinary care, and professional caretakers. Not bad for a dog that never had to fill out a job application.

3. Toby Rimes – The Poodle That Started It All

Long before millionaire pets became headline news, there was Toby Rimes. In the 1930s, New York socialite Ella Wendel reportedly left approximately $15 million (worth far more in today's dollars) in trust for her poodle.

While historians debate some details of the estate and trust arrangements, Toby became one of the earliest examples of an incredibly wealthy dog supported through an inheritance. His story helped create the enduring image of the "millionaire dog."

4. Lulu – The Border Collie Who Became a Millionaire Overnight

In 2021, an 84-year-old businessman from Tennessee left $5 million in a trust for his Border Collie named Lulu. The money wasn't simply handed to the dog. Instead, the trust was established to pay for Lulu's care throughout her life. Her caretaker can request reimbursement for expenses associated with caring for Lulu, subject to the terms of the trust.

It's an important reminder that, in many cases, pets don't legally "own" inherited money. Instead, the funds are managed through a pet trust for their benefit. Still… five million dollars buys a lot of tennis balls.

5. Gigoo – The Millionaire Chicken That Proves It Isn't Just Dogs

Okay, we're cheating just a little. Gigoo wasn't a dog — she was a chicken. British publisher Miles Blackwell left approximately £10 million to his beloved hen after his wife passed away.

Why include Gigoo on a dog list? Because it proves wealthy pet inheritances aren't limited to dogs. If chickens can become millionaires, your Golden Retriever may still have a chance.

Can Dogs Actually Inherit Money?

Legally speaking, dogs cannot directly own money or property in most jurisdictions. Instead, responsible pet owners typically establish a pet trust. A pet trust allows money to be managed by a trustee who uses those funds solely for the care of the animal.

The trust can cover expenses such as:

  • Food and gourmet treats
  • Veterinary care and medications
  • Grooming and boarding
  • Toys and enrichment
  • Housing and caretaker compensation
  • End-of-life care

Anything left after the pet passes away usually goes to other beneficiaries named in the trust.

Why Do Some People Leave Millions to Their Pets?

For many owners, pets truly are family. Some wealthy individuals have no children or close relatives and simply want to ensure their beloved companion receives excellent care for the rest of its life. Others leave generous trusts because they're concerned relatives may neglect the animal after they're gone.

In short, these inheritances are usually about providing lifelong care — not creating a canine billionaire with a debit card.

Could Your Dog Become Rich?

Probably. Could your dog become richer than you? That's a different question. Unless your pup has a billionaire owner — or has somehow figured out how to trade stocks while you're at work — the odds are fairly slim.

Still, if your dog suddenly starts insisting on filet mignon instead of kibble, you might want to ask if they've been meeting with an estate attorney behind your back.

Final Thoughts

The stories of dogs that inherited fortunes remind us just how deep the bond between humans and their pets can be. While the headlines often focus on the dollar amounts, these stories are really about owners wanting to make sure their loyal companions are cared for long after they're gone.

Whether your dog dreams of a mansion or is perfectly happy chasing squirrels in the backyard, one thing is certain: to them, you're already worth a million bucks.
