Dogs are often hailed as man’s most loyal companions—faithful, protective, and endlessly affectionate. Yet, in a handful of horrifying incidents, the very animals meant to safeguard us have turned lethal, leaving behind grim tales of 10 people killed by their own dogs. Below we count down the most unsettling accounts, each one a stark reminder that even the friendliest‑looking pup can become a deadly threat.
10 Bethany Lynn Stephens
On December 13, 2017, 22‑year‑old Bethany Lynn Stephens set out for a routine walk with her two pit bulls, never to return. The following day, her badly mutilated remains were discovered in a field, confirming that the dogs had turned on her.
Police observed the dogs guarding her corpse, refusing any approach. Officers kept a safe distance for several hours while the animals were eventually separated. During that time, they watched one of the pit bulls begin to consume Stephens’s body.
The gruesome scene sparked wild speculation that a rape‑murder might have occurred, but investigators concluded the dogs were responsible. To quell rumors, police released detailed findings, emphasizing that no external assailant was involved. Stephens had recently moved out of her parents’ home but continued to visit daily to walk the dogs she had left behind, until that fateful December 13, when the pit bulls attacked, biting her head, face, throat, hands, and arms as she struggled to defend herself.
9 Tania Klemke
Tania Klemke lived in Canberra, Australia, with a dog that resembled a pit bull. In October 2017, neighbors heard a man screaming inside her home and called police. When officers arrived, they found Klemke badly mauled; she succumbed to her injuries shortly thereafter, while the man she lived with survived his own bite wounds.
The dog had earned a reputation for aggression, frightening even Klemke herself. She warned friends to stay away, yet she clung to the animal because it had once saved her life during a robbery. A broken fence prevented her from keeping the dog outdoors.
The animal frequently growled at neighbors, even approaching windows to bark. It had previously attacked several neighbors—including children—and once inflicted a 42‑stitch wound on a visitor.
8 Linda Oliver
In 2013, 63‑year‑old Linda Oliver and her husband rescued a roaming rottweiler‑mastiff (some reports say a Labrador mix). Their act of kindness turned tragic when the dog bit Linda to death just days later.
While Linda was trying to intervene as the adopted dog attacked her smaller pet in the yard, the larger animal turned its fury on her. She managed to crawl inside and call her husband, but by the time authorities arrived, she had already died.
The dog remained in the yard, blocking officers from entering the home. Police eventually shot the animal, though it initially escaped, later being tracked down and killed.
7 Mario Perivoitos
In 2017, documentary filmmaker Mario Perivoitos was fatally bitten by his own Staffordshire Bull Terrier, Major, while a BBC crew filmed a drug‑related documentary at his home.
After ingesting cocaine, Perivoitos suffered an epileptic seizure and retired to bed. Meanwhile, Major—high on cocaine and heroin—attacked, gnawing at his face and neck. The crew attempted to intervene, but the dog continued until police forced entry about thirty minutes later.
Officers struggled for ten minutes to breach the heavily fortified door, typical of a drug‑dealer’s hideout. Perivoitos later died in hospital, and tests revealed Major had consumed a drug cocktail eight times the legal driving limit.
6 Della Riley
In August 2018, Cincinnati resident Della Riley experienced a seizure at home. Her son rushed out for help, and neighbors quickly called emergency services. When responders arrived, they found one of Riley’s two dogs viciously attacking her, while the second dog stayed out of the fray.
The aggressive dog remained inside, preventing paramedics from reaching Riley. Police had to intervene and fire upon the animal; one of the bullets struck Riley, piercing her abdomen. An autopsy later confirmed she had already died before the shot was fired.
5 Phyllis G. Carroll
In 2007, 63‑year‑old Phyllis G. Carroll was killed by one of her two five‑year‑old chow‑mix dogs—a larger male and a smaller female. Police could not definitively identify which dog delivered the fatal bite, though the male was suspected.
Authorities believe Carroll was about to feed the dogs when the male lunged, clamping onto her arm. She fell to the ground, where the enraged dog then bit her throat. Prior to the incident, Carroll had confided to friends that the male dog’s aggression was escalating.
Both dogs were seized and euthanized following the tragedy.
4 Kelli Chapman
In 2008, 24‑year‑old Kelli Chapman was mauled to death in her bedroom by her two pit bulls. Her husband, Jason Chapman, discovered her body and called 911 at 6:49 PM on a Sunday.
Kelli suffered extensive bite wounds on both forearms, and furniture in the room bore visible damage. Witnesses reported she fought back against the dogs, suggesting a seizure may have triggered the attack.
Two years earlier, the Chapmans had experienced a separate incident: during a 2006 drug raid, their pit bull attacked officers, biting one and attempting to bite another before being shot.
3 Lorraine May
In 2008, 74‑year‑old Lorraine May from Florida was fatally bitten while trying to break up a fight between her two dogs: an 11‑year‑old golden retriever mother and her 6‑year‑old Australian Shepherd mix son, who had a history of constant brawling.
It remains unclear whether one or both dogs were responsible, but evidence suggests her attempt to intervene was mishandled, leading the animal(s) to turn on her. Experts warn against single‑handed interference in dog fights.
Proper protocol calls for at least two people to each grab a dog’s hind legs and gently separate them, or to use a blanket, a loud noise, or a water spray to distract the animals.
2 Hill Andrew Williams
In 2009, 38‑year‑old Hill Andrew Williams met a grisly end at the hands of his two mastiff dogs in his California residence. While the exact motive remains uncertain, investigators suspect the dogs, a 52‑kg male named Butter and a 41‑kg female named Ivory, attacked after Williams interrupted them during a mating session.
Neighbors alerted the Rancho Mirage police after spotting Williams bleeding in his backyard. A friend who visited noted severe arm injuries, and officers later found both mastiffs in the yard. Williams was pronounced dead at the hospital.
1 Unnamed Woman And Her Son
A 52‑year‑old unnamed woman and her 27‑year‑old son were slain by their Staffordshire Terrier in Hanover, Lower Saxony, Germany. The attack went unnoticed until a neighbor spotted a body through a window and called emergency services.
Firefighters managed to capture the dog before reaching the victims. Germany, like the United States, grapples with dog‑mauling incidents. To curb such tragedies, Lower Saxony introduced a “dog holding licence,” requiring prospective owners to pass an initial test and a follow‑up assessment within a year.
+ Sandra Piovesan
In 2006, 50‑year‑old Sandra Piovesan was killed by a pack of nine wolf‑dogs she kept in her Westmoreland County, Pennsylvania, backyard. She also owned two rottweilers, which were housed separately from the wolf‑dogs.
Piovesan divided her expansive yard—roughly the width of a three‑lane road—into three zones: one for the wolf‑dogs, another for their puppies, and a third for the rottweilers. She registered the wolf‑dogs as ordinary dogs to bypass Pennsylvania Game Commission regulations.
Neighbors complained about the foul odor from raw meat, roadkill, and other flesh she fed the pack. The wolf‑dogs behaved like a true pack, with Piovesan acting as the alpha. Internal strife erupted when the dogs fought, killing an older member as they vied for dominance, and one may have turned on Piovesan to claim leadership.
These chilling accounts underscore that even beloved pets can become lethal under certain circumstances. Understanding warning signs, securing proper training, and adhering to local regulations are vital steps to prevent such tragedies.
