20 Worst Dog Breeds for Cats: Feline-Unfriendly Canines to Avoid

Choosing a dog breed when you have cats at home requires careful consideration. Not all dogs get along well with felines, and some breeds may pose risks to cats due to their prey drive or size difference.

Understanding which breeds are less compatible with cats can help pet owners make informed decisions.

The 20 worst dog breeds for cats represent various sizes, temperaments, and instincts that may conflict with feline companions.

These breeds often have strong hunting instincts, high energy levels, or physical characteristics that can make coexistence challenging.

By examining these breeds, potential dog owners can better evaluate their options and create a harmonious multi-pet household.

1. Alaskan Malamute

Alaskan Malamutes are large, powerful dogs with a strong prey drive. Their size and strength make them potentially dangerous to cats.

These dogs were originally bred for sledding and hunting, which contributes to their high prey drive. They may view cats as potential prey rather than companions.

Malamutes are known for their thick coats and wolf-like appearance. Their imposing presence can be intimidating to smaller animals, including cats.

Training and socialization are crucial for Alaskan Malamutes. Even with proper training, their instincts may still pose a risk to feline housemates.

Introducing an Alaskan Malamute to a household with cats requires careful supervision and management. It’s essential to consider the safety of both animals when contemplating this combination.

2. American Pit Bull Terrier

American Pit Bull Terriers have a strong prey drive, making them potentially dangerous for cats. These dogs were originally bred for hunting and fighting, which can trigger their instinct to chase smaller animals.

Their muscular build and powerful jaws pose a significant risk to felines. Even if not intending harm, a Pit Bull’s playful behavior could accidentally injure a cat due to the size difference.

Proper socialization and training from an early age are crucial for Pit Bulls living with cats. Without this, their natural tendencies may lead to aggressive behavior towards felines.

Some Pit Bulls can coexist peacefully with cats, especially if raised together. However, the breed’s predisposition to high energy and strength means constant supervision is necessary to ensure the cat’s safety.

3. Australian Cattle Dog

Australian Cattle Dogs are known for their high energy and strong herding instincts. These traits can make them challenging companions for cats.

Their natural drive to chase and herd can be directed towards felines, causing stress and potential injury. Australian Cattle Dogs may attempt to control a cat’s movements, leading to conflicts.

These dogs have a strong prey drive, which can be triggered by a cat’s quick movements. This instinct may cause them to pursue cats aggressively, even if they don’t intend harm.

Australian Cattle Dogs require extensive exercise and mental stimulation. Without proper outlets, they may focus their energy on chasing or harassing cats in the household.

Training and socialization can help mitigate these issues, but the breed’s inherent traits make them less than ideal housemates for cats. Careful management and supervision are necessary when introducing an Australian Cattle Dog to a home with felines.

4. Basenji

Basenjis are known for their high prey drive and cat-chasing tendencies. These small, athletic dogs were originally bred for hunting in Africa, which contributes to their strong pursuit instincts.

Basenjis possess a keen sense of smell and sharp eyesight, making them quick to spot and chase cats. Their agility and speed allow them to easily pursue felines, potentially causing stress or harm.

While Basenjis are generally quiet dogs, they may bark or make other vocalizations when excited by the presence of a cat. This behavior can further agitate feline companions in the household.

Early socialization and training are crucial for Basenjis to coexist peacefully with cats. However, even with proper introduction and management, their natural hunting instincts may persist, making them a challenging breed for cat owners.

5. Beagle

Beagles possess a strong hunting instinct that can make them challenging companions for cats. Their keen sense of smell and natural prey drive may lead them to chase felines, causing stress and potential harm.

These dogs were originally bred for hunting small game, including rabbits. This background contributes to their high energy levels and tendency to follow scents, which can be problematic in a home with cats.

Beagles are known for their loud, baying voices. This vocalization can startle and upset cats, creating an uncomfortable living environment for feline residents.

While some Beagles can coexist peacefully with cats, proper training and early socialization are crucial. Without these, the breed’s innate instincts may prove too strong, leading to a stressful situation for both animals.

While some Great Danes can learn to live peacefully with cats, their size difference and prey drive make them a challenging breed for feline companions.

16. Jack Russell Terrier

Jack Russell Terriers possess a strong prey drive and high energy levels, making them a challenging breed to coexist with cats. These small but tenacious dogs were originally bred for hunting, which can translate to chasing and potentially harming felines.

Their quick movements and tendency to bark excitedly may startle or stress cats. Jack Russells often view smaller animals as targets, potentially triggering their instinct to pursue.

Training and socialization can help mitigate these tendencies, but the breed’s inherent nature may still pose risks. Early and consistent exposure to cats can improve their ability to coexist, but supervision is crucial.

Jack Russell Terriers require ample exercise and mental stimulation. Without proper outlets for their energy, they may become more likely to engage in problematic behaviors around cats.

17. Manchester Terrier

Manchester Terriers possess a strong prey drive, making them potentially challenging companions for cats. These agile dogs were originally bred for hunting small animals, including rodents.

Their quick reflexes and high energy levels can be intimidating to felines. Manchester Terriers may chase cats, viewing them as potential prey rather than housemates.

Training and socialization from an early age are crucial for Manchester Terriers to coexist peacefully with cats. Even with proper training, their instincts may still surface unexpectedly.

The breed’s tenacity and determination can lead to persistent pursuit of cats. This behavior may cause stress for feline members of the household.

Supervision is essential when introducing Manchester Terriers to cats. Owners should be prepared to manage interactions carefully to ensure the safety of both pets.

18. Miniature Schnauzer

Miniature Schnauzers can pose challenges when living with cats. These energetic terriers have a strong prey drive, which may lead them to chase or harass feline housemates.

Their territorial nature can cause conflicts with cats over shared spaces. Miniature Schnauzers often bark excessively, potentially startling or stressing out cats in the home.

These dogs require extensive exercise and mental stimulation. Without proper outlets, they may direct their energy towards pestering cats. Their high-strung temperament can clash with the typically calmer nature of cats.

Early socialization and training are crucial for Miniature Schnauzers to coexist peacefully with cats. Even with proper introduction, some individuals may never fully adapt to feline companions.

19. Pekingese

Pekingese dogs can be challenging housemates for cats due to their strong-willed and territorial nature. These small but sturdy dogs were historically bred as companions for Chinese royalty, resulting in a confident and sometimes stubborn personality.

Pekingese tend to be protective of their space and possessions, which may lead to conflicts with curious cats. Their short stature can also make them feel threatened by larger felines, potentially causing defensive reactions.

While some Pekingese can coexist peacefully with cats, their low tolerance for rough play and tendency to snap when annoyed pose risks. Proper socialization and training from an early age are crucial for fostering positive interactions between Pekingese and cats.

Supervision is essential when introducing a Pekingese to a household with cats. Gradual introductions and creating separate spaces for each pet can help reduce tension and promote a more harmonious living environment.

20. Siberian Husky

Siberian Huskies possess a strong prey drive, making them potentially challenging companions for cats. These energetic dogs were originally bred for sledding, which contributes to their high exercise needs and tendency to chase small animals.

Their natural instinct to hunt can lead to aggressive behavior towards felines. Huskies may view cats as prey rather than potential friends, especially if not properly socialized from a young age.

The size difference between Siberian Huskies and cats also poses a risk. Even playful interactions could result in accidental injury to a smaller feline companion.

Training and early socialization can help mitigate some of these issues. However, the inherent prey drive of Siberian Huskies remains a concern for cat owners considering this breed.

Behavioral Challenges

Certain dog breeds pose distinct behavioral challenges when living with cats. These issues stem from innate instincts and traits that can make coexistence difficult.

Aggression and Dominance

Some dog breeds exhibit strong dominance behaviors that clash with cats. These dogs may view cats as rivals or intruders in their territory. They often display aggressive posturing, growling, or even physical confrontation.

Breeds like Rottweilers and German Shepherds can be particularly prone to dominance-related aggression toward cats. Their large size and protective nature exacerbate this issue.

Training and socialization from an early age are crucial for these breeds. However, even with proper training, their natural tendencies may persist.

Prey Drive and Chase Instincts

Many dog breeds have a high prey drive, making them likely to chase or hunt cats. This instinct can be dangerous for felines, even if the dog doesn’t intend harm.

Sighthounds like Greyhounds and Whippets have an exceptionally strong chase drive. Their speed and agility make them a serious threat to cats.

Terriers, bred for hunting small animals, often view cats as prey. Jack Russell Terriers and Fox Terriers are notorious for this behavior.

Even playful chasing can be stressful for cats. It’s important to supervise interactions and provide safe spaces for cats to retreat.

Environmental Considerations

The living environment plays a crucial role in dog-cat relationships. Shared spaces and outdoor interactions can significantly impact the dynamics between these pets.

Shared Living Spaces

Dogs with high prey drives or territorial tendencies may struggle to coexist with cats in confined areas. Breeds like Siberian Huskies and Australian Cattle Dogs often need ample space to roam, making small apartments challenging for cat cohabitation.

Some large breeds, such as Great Danes or Saint Bernards, might accidentally harm cats due to their size in tight quarters. These dogs may unintentionally step on or knock over feline housemates.

Terriers, bred for hunting small animals, may view cats as prey in enclosed spaces. This instinct can lead to chasing or aggressive behavior towards feline companions.

Outdoor Interactions

Certain dog breeds pose risks to cats during outdoor encounters. Greyhounds and Whippets, with their strong chase instincts, may pursue cats they spot in yards or on walks.

Hunting breeds like Beagles or Bloodhounds can become fixated on a cat’s scent, potentially leading to dangerous pursuits if not properly controlled.

Some herding breeds, such as Border Collies or Australian Shepherds, might attempt to herd cats outdoors. This behavior can stress or frighten felines unaccustomed to such treatment.

Larger working breeds like Rottweilers or Doberman Pinschers may view unfamiliar cats as threats to their territory, leading to aggressive responses during chance outdoor meetings.

Training and Socialization

Proper training and socialization are crucial for dogs living with cats. These techniques help create a harmonious multi-pet household and reduce the risk of conflict.

Early Intervention Strategies

Introducing dogs and cats at a young age can lead to better outcomes. Puppies are more adaptable and can learn to coexist with felines more easily. Gradual, controlled introductions are key. Start by keeping the animals in separate rooms, allowing them to smell each other through closed doors.

Next, use baby gates to create visual contact while maintaining physical separation. This allows both pets to observe each other safely. Supervise all interactions closely and keep initial meetings brief. Increase duration as the animals become more comfortable.

Teach basic obedience commands to the dog, such as “sit,” “stay,” and “leave it.” These skills help manage the dog’s behavior around cats.

Positive Reinforcement Techniques

Reward-based training is effective for encouraging good behavior between dogs and cats. Use treats, praise, and toys to reinforce calm, non-aggressive interactions. When the dog ignores or behaves calmly around the cat, offer immediate rewards.

Redirect the dog’s attention if it shows too much interest in the cat. Engage the dog in alternative activities or commands to shift focus. This helps prevent chasing or predatory behaviors.

Create positive associations by feeding both pets in the same room, but at a safe distance. Gradually decrease the distance as they become more comfortable. This technique helps them associate each other’s presence with pleasant experiences.

Provide separate resources for each pet, including food bowls, water dishes, litter boxes, and resting areas. This reduces competition and potential conflicts.
