These 13 Dog Breeds Are The Worst According To Some Experts

Oct 10, 2025bySarah McConnell

Every dog deserves love, patience, and proper care. But some breeds come with traits that even experienced owners find challenging.

Certain dogs simply aren’t a good fit for everyone. That doesn’t make them bad; it just means they need the right environment, consistent training, and a lot of understanding. This list looks at dog breeds that some experts consider among the most difficult to handle.

Whether it’s their size, temperament, or exercise demands, these breeds remind us that choosing a dog should never be about looks alone, it’s about finding a companion whose personality matches your lifestyle.

This article is for general knowledge only and is based on information from online sources. Every dog is an individual, and behaviour can vary widely depending on training, socialisation, and environment.

1. Chow Chow

With a lion-like mane and an independent streak, the Chow Chow can be quite the handful. This ancient Chinese breed tends to bond strongly with one person while remaining distant with others. Their aloof nature makes socialization difficult, and they often show aggression toward strangers or other dogs.

Training requires patience since Chows are notoriously stubborn. They need experienced handlers who understand their territorial instincts. Without proper guidance, these dogs may become overly protective of their homes and families, leading to behaviour problems that frustrate many owners.

2. Dalmatian

Those iconic spots might look adorable, but Dalmatians pack endless energy that exhausts unprepared families. Originally bred to run alongside carriages for miles, they require intense daily exercise that most households cannot provide. Without sufficient activity, they become destructive and anxious.

Dalmatians also suffer from genetic deafness more than other breeds, complicating training efforts. Their high-strung temperament means they often overwhelm young children with their boisterous play. Many end up in shelters when owners realize the commitment these dogs truly demand for a balanced, happy life.

3. Akita

Akitas carry a reputation for fierce loyalty, but that devotion comes with serious drawbacks. This Japanese breed shows extreme territorial behaviour and often displays aggression toward other animals and unfamiliar people. Their powerful build makes controlling them challenging, especially when protective instincts kick in.

Early socialization helps, yet many Akitas never fully trust strangers regardless of training. They demand confident owners who establish clear leadership from day one. Families with multiple pets or frequent visitors may find Akitas too unpredictable, as their guardian nature can quickly escalate into dangerous situations without warning.

4. Siberian Husky

Those piercing blue eyes hide a mischievous escape artist with boundless stamina. Huskies were bred to pull sleds across frozen tundra, so suburban life rarely satisfies their exercise needs. They dig under fences, leap over barriers, and bolt through open doors with impressive determination.

Their vocal nature means constant howling that annoys neighbours. Huskies shed heavily year-round and possess a stubborn streak that makes obedience training frustrating. Without several hours of vigorous activity daily, they channel energy into destructive behaviour that leaves homes in shambles and owners completely overwhelmed.

5. Rottweiler

Rottweilers possess incredible strength paired with a protective instinct that can turn problematic. Originally cattle herders, they naturally guard their territory with intensity that frightens visitors and delivery workers alike. Their size alone intimidates, but add territorial aggression and the combination becomes dangerous.

These dogs need firm, consistent training from experienced handlers who understand dominance behaviours. Without proper socialization, Rottweilers may interpret normal situations as threats, responding with force. Insurance companies often exclude them from coverage due to bite statistics, creating additional complications for owners who underestimate their demanding nature.

6. Basenji

Known as the barkless dog, the Basenji produces an eerie yodel that catches owners off guard. This African breed combines cat-like independence with a stubborn refusal to obey commands. They groom themselves meticulously yet remain nearly impossible to train using conventional methods.

Basenjis possess strong prey drives and will chase anything that moves, making off-leash time risky. Their intelligence works against owners as they outsmart barriers and find creative ways to misbehave. Many people attracted to their unusual qualities quickly discover these dogs require patience and creativity that exceeds their expectations.

7. Jack Russell Terrier

Small size fools people into thinking Jack Russells make easy companions, but their energy levels rival much larger breeds. Bred to hunt foxes underground, they possess relentless stamina and a fearless attitude that creates constant chaos. They bark excessively, dig compulsively, and challenge every boundary set for them.

Their intelligence means they bore easily without mental stimulation, leading to destructive creativity. Jack Russells often develop aggression toward other dogs despite their diminutive stature. Apartment living proves disastrous, as these terriers need space to burn energy that never seems to deplete completely.

8. Chihuahua

Despite weighing mere pounds, Chihuahuas pack enormous attitude into tiny bodies. Their nervous temperament leads to constant yapping that drives neighbours mad. They often bite when startled or threatened, making them unsuitable around young children who handle them roughly.

Chihuahuas bond intensely with one person and show jealousy toward others seeking attention. Housetraining proves incredibly difficult due to their small bladders and stubborn personalities. Many owners spoil them, reinforcing bad behaviour that turns these pocket-sized pups into tyrants. Their fragility also means vet bills add up quickly from injuries sustained during everyday activities.

9. Beagle

Those soulful eyes and floppy ears disguise a hound driven entirely by its nose. Beagles follow scent trails with single-minded determination, ignoring commands once they catch an interesting smell. Their baying howl carries for blocks, creating noise complaints from frustrated neighbours.

Food obsession leads Beagles to counter-surf, raid garbage, and steal meals whenever possible. They gain weight easily, requiring strict portion control that challenges owners. Escape artists by nature, they slip through gaps and tunnel under fences while pursuing scents. Recall training rarely succeeds since instinct overpowers obedience every single time.

10. Afghan Hound

Elegant appearance masks a breed that challenges even experienced dog owners. Afghan Hounds possess an independent spirit that makes training feel impossible. They ignore commands they find unreasonable, preferring to make their own decisions about everything.

Their luxurious coat requires hours of grooming weekly to prevent painful matting. Afghans need substantial exercise but cannot be trusted off-leash due to their strong chase instinct. They remain emotionally distant, rarely showing the affection most people expect from dogs. Veterinary care costs more since their unique build creates specific health concerns that demand specialized attention throughout their lives.

11. Pekingese

Bred for Chinese royalty, Pekingese still act like they deserve palace treatment. Their flat faces cause breathing problems that lead to snoring, snorting, and overheating in warm weather. Housetraining takes months or even years due to their stubborn refusal to cooperate.

These dogs demand constant attention and become jealous of anyone else receiving affection. Their long coat mats easily without daily grooming, creating painful tangles. Pekingese often snap at children who approach too quickly or handle them incorrectly. Health issues plague the breed, including eye problems and back troubles that result in expensive veterinary bills.

12. Bulldog

That adorable wrinkled face comes with serious health complications that burden owners emotionally and financially. Bulldogs suffer from breathing difficulties due to their flat faces, making exercise dangerous in warm weather. They snore loudly, drool constantly, and struggle with simple activities other dogs handle easily.

Skin folds require daily cleaning to prevent painful infections. Many Bulldogs cannot breed or give birth naturally, requiring expensive artificial insemination and cesarean sections. Hip problems, cherry eye, and heart conditions plague the breed. Despite their loving personalities, the medical care they need throughout their shortened lifespans overwhelms many families.

13. Shar Pei

Those signature wrinkles look unique but create ongoing health nightmares for owners. Skin folds trap moisture and bacteria, leading to chronic infections that require constant monitoring. Shar Peis also suffer from a painful eye condition where lashes grow inward, often needing surgical correction.

Beyond physical issues, their temperament challenges inexperienced handlers. They show aloofness toward strangers and aggression toward other dogs without proper socialization. Training requires patience since they possess stubborn streaks typical of ancient guardian breeds. Combined with high grooming and medical needs, Shar Peis demand commitment that exceeds what most families anticipate when drawn to their distinctive appearance.
