Brutus and Hobbs, Dwayne "The Rock" Johnson's French Bulldogs

Dwayne Johnson, The Rock, is one of the strongest men in Hollywood: six foot five, a former WWE champion, and the lead in half a catalog of action blockbusters. In 2015 he posted a message on social media that showed him at his most vulnerable, grieving the death of a French Bulldog puppy named Brutus. Behind that post sits a story that mixes two things: a celebrity's attachment to a very small breed, and a health warning that applies to anyone who owns a dog.

Two puppies: Brutus and Hobbs

Johnson had two French Bulldog puppies, littermate brothers named Brutus and Hobbs. The second name is a nod to his own character, Luke Hobbs, from the Fast & Furious franchise. The two were being raised together and spent their days playing in the yard of the actor's home.

September 2015 brought a first scare. Johnson described having to pull Brutus out of his swimming pool after the puppy fell in and could not swim. That detail matters for anyone considering the breed, because the French Bulldog is one of the worst swimmers in the canine world. A compact body, a large heavy head, and dense muscle sink it easily, so a pool without a fence or an exit ramp is a genuine hazard.

The mushroom that killed Brutus

A short time after that rescue, on September 29, 2015, Brutus died. While playing outside with his brother Hobbs, he ate a toxic mushroom growing in the yard. According to Johnson's account, the poison rapidly destroyed the puppy's liver and immune system past the point of no return, and the family made the decision to take him off life support.

Johnson used his enormous audience to deliver a concrete warning to other owners: check for mushrooms in yards, parks, and anywhere dogs play, because something that looks harmless can be lethal to a small animal. Coming from someone with tens of millions of followers, that message did more for awareness of toxic mushrooms than many veterinary campaigns.

Why a mushroom can kill a dog in hours

What happened to Brutus fits a pattern that ASPCA Animal Poison Control describes well. Most wild mushrooms are harmless, but certain species in the genus Amanita, including Amanita phalloides (the "death cap"), carry amatoxins capable of triggering acute liver failure. A single mushroom can hold a lethal dose for a small dog.

The treacherous part is the symptom timeline. After ingestion there can be a deceptively quiet window of 6 to 12 hours before the first digestive signs appear (vomiting, diarrhea, lethargy), per the ASPCA. By the time the owner gets alarmed, the toxins are already damaging the liver, and severe cases can end in death within a day or two. A puppy weighing a few pounds, like Brutus, has far less margin than a large adult dog.

What to do if you suspect your dog ate a mushroom:

• Do not wait for symptoms. A quiet stretch with no signs does not rule out poisoning.
• Get to an emergency veterinarian immediately. Time is the factor that weighs most on the prognosis.
• If you can, photograph the mushroom or save a piece in a paper bag to help identify the species.
• Check the yard after rain. Mushrooms sprout fast in damp, shaded spots with decomposing organic matter.
• When in doubt, call a veterinary poison hotline (ASPCA Animal Poison Control or Pet Poison Helpline) before trying anything on your own.

The French Bulldog: a tiny breed with a long instruction manual

Brutus and Hobbs belonged to one of the most popular breeds on the planet. The American Kennel Club has ranked the French Bulldog the most popular breed in the United States since 2022, ahead of the Labrador Retriever. Its success comes down to an apartment-sized frame, bat ears, and a temperament the AKC describes as playful, alert, and adaptable. The AKC places the breed in the Non-Sporting Group.

The breed by the numbers:

• Weight: the AKC standard caps it at 28 lb (about 13 kg); most adults run 17 to 28 lb (8 to 13 kg).
• Life expectancy: roughly 10 to 12 years.
• Looks: a sturdy, compact body, a short coat, a flat muzzle, a naturally short tail, and the trademark upright ears.
• Temperament: sociable, attached to the family, a quiet barker, built as an urban companion dog.

The French Bulldog is a charming dog with fragile health, and that health deserves a hard look before buying one.

The breathing problem: the flat face comes at a price

The French Bulldog is a brachycephalic breed, meaning the skull and muzzle are severely shortened. The flattened face people find so appealing is the product of human selection that compressed the skull's structure without shrinking the soft tissue inside to match. Veterinary literature calls the result Brachycephalic Obstructive Airway Syndrome (BOAS): narrowed nostrils, an elongated soft palate, and obstructed airways that make breathing harder.

That has a direct day-to-day consequence. Dogs cool themselves mainly by panting, and a brachycephalic dog pants poorly because it has less usable airway surface. The Merck Veterinary Manual warns that brachycephalic breeds are especially vulnerable to heat stroke, since their anatomy keeps them from shedding heat efficiently. A hot day, a long midday walk, or a closed car can turn lethal for a Frenchie long before it would for a long-muzzled dog.

Baseline care for the breed:

• Skip intense exercise in the heat. Walk early or after sundown in summer, and watch for excessive panting.
• Never leave a French Bulldog in a closed car, cracked windows included.
• Keep the weight in check. Extra pounds worsen breathing and aggravate the brachycephalic syndrome.
• Watch pools and open water. This is a poor swimmer; use a canine life vest anywhere near water.
• See a veterinarian if the dog snores heavily, chokes when excited, or tolerates exercise badly: these are BOAS signs that sometimes call for corrective surgery.

What the story of Brutus leaves behind

Hobbs, the surviving brother, stayed by Johnson's side for years, until his death in February 2025. Johnson has since owned more French Bulldogs and other dogs. The Brutus episode endures as one of those moments when a celebrity used his platform for something useful: a reminder that a seemingly safe backyard can hide a deadly poison.

The double lesson is simple. First, wild mushrooms are a real and underestimated risk for dogs, and the only correct plan when ingestion is suspected is the emergency vet without delay. Second, the French Bulldog is a wonderful companion breed and one of the most delicate dogs in existence: it breathes with difficulty, swims terribly, and handles heat poorly. Anyone tempted by one, whether by fashion or because The Rock has them, should go in knowing they are bringing home an adorable dog with a demanding care manual.
