20 Worst Dog Breeds for Home Security: Friendly Pups That Won’t Deter Intruders
Dogs are often considered valuable companions for home security, but not all breeds excel in this role.
Some canines lack the protective instincts, size, or temperament needed to effectively deter intruders or alert their owners to potential threats.
This article examines 20 dog breeds that may not be ideal choices for enhancing home security.
While these dogs can make wonderful pets in many other ways, their characteristics may limit their effectiveness as guard dogs or watchdogs.
Understanding the strengths and limitations of different breeds can help potential owners make informed decisions about canine companions for various purposes, including home protection.
1. Chihuahua
Chihuahuas are known for their small size and feisty personalities. While they may bark loudly at perceived threats, their diminutive stature makes them ineffective as guard dogs.
These tiny canines typically weigh between 2 and 6 pounds, standing only 6 to 9 inches tall at the shoulder. Their small size limits their ability to physically deter intruders or protect a home.
Chihuahuas are often more likely to retreat or hide when faced with genuine danger. Their bark might alert homeowners to potential issues, but they lack the intimidating presence needed for effective home security.
Despite their loyal nature, Chihuahuas are not naturally aggressive towards strangers. They may be wary of unfamiliar people, but this trait alone does not make them suitable guard dogs.
2. French Bulldog
French Bulldogs are beloved companions known for their charming personalities and compact size. However, they make poor guard dogs due to their friendly nature and lack of protective instincts.
These dogs rarely bark, which is a disadvantage when it comes to alerting homeowners to potential intruders. Their small stature also limits their ability to physically deter or confront threats.
French Bulldogs are more likely to greet strangers with enthusiasm rather than suspicion. Their affectionate disposition makes them unsuitable for home security roles.
Additionally, their brachycephalic features can lead to breathing difficulties, limiting their endurance and ability to respond quickly in high-stress situations. This breed is better suited as a loving family pet rather than a security asset.
3. Pug
Pugs are small, compact dogs known for their wrinkled faces and flat noses. While they make lovable companions, they are not ideal for home security purposes.
Pugs typically weigh between 14 to 18 pounds and stand about 10 to 13 inches tall. Their small stature makes them unlikely to deter potential intruders.
These dogs have a friendly and gentle temperament. They are more likely to greet strangers with enthusiasm rather than show any protective instincts.
Pugs are not known for their barking abilities. They may occasionally alert their owners to noises, but they lack the loud, intimidating bark needed for effective home security.
Additionally, pugs have limited physical capabilities due to their brachycephalic (flat-faced) features. This can lead to breathing difficulties, especially during physical exertion, making them unsuitable for guarding duties.
4. Basset Hound
Basset Hounds are not ideal for home security due to their gentle and friendly nature. These dogs are known for their laid-back temperament and are unlikely to show aggression towards strangers.
Their short legs and long bodies make Basset Hounds slow-moving, reducing their ability to chase or intimidate intruders. They lack the agility and speed necessary for effective guard dog duties.
Basset Hounds have a tendency to bark, but their deep, melodious voices may not sound threatening enough to deter potential burglars. Their vocalizations are often more amusing than alarming.
While affectionate and loyal to their families, Basset Hounds are generally too trusting of strangers to serve as effective watchdogs. They may greet intruders with wagging tails rather than protective behavior.
5. Shih Tzu
Shih Tzus are small, adorable companion dogs known for their friendly and affectionate nature. These lap dogs typically weigh between 9-16 pounds and stand about 8-11 inches tall.
While Shih Tzus make excellent family pets, they are not suitable as guard dogs. Their small size and gentle temperament render them ineffective at deterring intruders or protecting property.
Shih Tzus are more likely to greet strangers with enthusiasm than display any aggressive behavior. They lack the physical strength and intimidating presence needed for home security purposes.
These dogs have a low prey drive and are not typically alert barkers. This means they may not even notify their owners of potential threats or unusual activities around the home.
In terms of home security, Shih Tzus are better suited as loving companions rather than watchdogs or protectors.
6. Italian Greyhound
Italian Greyhounds are small, slender dogs known for their gentle and affectionate nature. While they make excellent companions, these graceful canines are not well-suited for home security purposes.
Their diminutive size and delicate build make them ill-equipped to deter or confront potential intruders. Italian Greyhounds typically weigh between 7 and 14 pounds, standing only 13 to 15 inches tall at the shoulder.
These dogs are often timid around strangers and may be easily startled by loud noises or sudden movements. Their natural inclination is to retreat rather than confront perceived threats.
Italian Greyhounds have a low bark volume and frequency, which limits their effectiveness as watchdogs. They are unlikely to alert homeowners to potential security risks.
7. Saint Bernard
Saint Bernards are known for their gentle and friendly nature, making them less than ideal for home security purposes. These massive dogs are often more likely to greet intruders with a wagging tail than a protective bark.
Their size can be intimidating, but Saint Bernards typically lack the aggressive instincts needed for effective guard dogs. They are generally calm and patient, even with strangers, which doesn’t align well with security duties.
Saint Bernards are also not particularly alert or quick to react to potential threats. Their laid-back temperament means they may not notice or respond to unusual sounds or activities around the home.
Additionally, these dogs require significant space and are not well-suited for small living areas. Their large size can make them less agile and slower to respond in emergency situations.
8. Pekingese
Pekingese dogs are not well-suited for home security tasks. Their small size and limited physical capabilities make them ineffective deterrents against potential intruders.
These dogs typically weigh between 7 to 14 pounds and stand only 6 to 9 inches tall at the shoulder. Their compact build and short legs restrict their ability to chase or confront threats.
Pekingese are known for their stubborn nature and independent personality. This trait can make them less responsive to commands, potentially hindering their effectiveness in alerting owners to danger.

9. Papillon
Papillons are charming and elegant toy dogs known for their butterfly-like ears. Despite their regal appearance, these small canines are not well-suited for home security duties.
Weighing in at a mere 5 to 10 pounds, Papillons lack the physical presence to deter intruders. Their diminutive size makes them ineffective as guard dogs against human threats.
While Papillons are alert and may bark at unfamiliar sounds, their high-pitched yaps are unlikely to intimidate potential burglars. These dogs are generally friendly and sociable, often greeting strangers with enthusiasm rather than suspicion.
Papillons are better suited as companion animals than security assets. Their gentle nature and small stature make them ill-equipped to protect a home or confront intruders.
10. Yorkshire Terrier
Yorkshire Terriers are diminutive dogs known for their long, silky coats and feisty personalities. Despite their bold attitudes, these tiny terriers typically weigh less than 7 pounds, making them ineffective as guard dogs.
Yorkies are more likely to alert their owners to potential intruders with their high-pitched barks. However, their small size means they pose little physical threat to burglars or other unwanted visitors.
These dogs are often more interested in seeking attention and affection from their owners than patrolling for security threats. Their friendly nature towards strangers further diminishes their effectiveness as home protectors.
While Yorkshire Terriers can be territorial, their tiny stature limits their ability to deter or confront intruders. They are better suited as companion animals rather than security assets for a household.
11. Maltese
Maltese dogs are known for their small size and adorable appearance. These fluffy white companions typically weigh between 4 to 7 pounds and stand no taller than 10 inches at the shoulder.
While Maltese are charming and affectionate pets, they are not well-suited for home security purposes. Their diminutive stature and gentle nature make them unlikely to deter potential intruders.

Their mild temperament makes them poor candidates for home security. Cavaliers are more likely to greet intruders with wagging tails than to deter them with barks or aggressive behavior.
These dogs have a strong desire to please their owners and form close bonds with family members. While this trait makes them excellent pets, it doesn’t translate to effective guard dog capabilities.
Cavalier King Charles Spaniels are generally quiet and not prone to excessive barking. This characteristic further diminishes their usefulness as watchdogs or home security assets.

13. Whippet
Whippets are known for their gentle and friendly nature, making them less than ideal for home security purposes. These slender, graceful dogs are often described as calm and quiet companions, unlikely to raise an alarm in the presence of intruders.
Whippets typically have a low prey drive when indoors, preferring to relax and conserve energy. This laid-back temperament means they may not react to unusual sounds or movements that could indicate a potential threat.
While Whippets are swift runners, they lack the assertive personality needed for an effective guard dog. Their small to medium size also limits their physical intimidation factor, which is an important aspect of deterring potential intruders.
Whippets are generally more inclined to greet strangers with a wagging tail than with any protective behavior. This friendly disposition, while endearing, does not contribute to their effectiveness as a home security measure.

Understanding the Traits of Guard Dogs
Guard dogs possess specific characteristics that make them effective protectors. These traits encompass physical attributes, behavioral tendencies, and specialized training requirements.
Physical Characteristics
Guard dogs typically have imposing physical features. Large breeds often excel in this role due to their intimidating size and strength. Many guard dogs have muscular builds, broad chests, and powerful jaws.
Breeds like German Shepherds, Rottweilers, and Doberman Pinschers are known for their athletic physiques. These dogs often have erect ears and alert expressions, enhancing their vigilant appearance.
Coat types vary among guard breeds. Some have short, dense fur, while others sport longer, thicker coats. Regardless of coat length, guard dogs usually have weather-resistant fur to withstand various environments.
Temperament and Behavior
Guard dogs exhibit distinct behavioral traits. They are naturally protective and territorial, with a strong instinct to defend their home and family. These dogs remain vigilant and attentive to their surroundings.
Loyalty is a key trait in guard breeds. They form deep bonds with their families and are willing to protect them fiercely. Many guard dogs display a reserved or aloof attitude towards strangers.
Intelligence and trainability are crucial for effective guard dogs. They must be able to distinguish between genuine threats and normal situations. Breeds like Belgian Malinois and Bullmastiffs combine intelligence with protective instincts.
Training and Socialization
Proper training is essential for guard dogs to perform their role effectively. Early socialization helps prevent aggression towards non-threatening individuals. Obedience training ensures the dog responds reliably to commands.
Guard dog training often includes specific protection exercises. These may involve teaching the dog to bark on command or to restrain an intruder safely. Professional trainers frequently assist in developing these specialized skills.
Consistent reinforcement of desired behaviors is crucial. Guard dogs need clear boundaries and rules to follow. Regular exercise and mental stimulation help channel their energy positively and maintain their alertness.
Common Misconceptions About Dog Breeds and Home Security
Many people have mistaken beliefs about which dog breeds are best for home security. These misconceptions often stem from stereotypes about size and temperament.
Small Breeds vs Large Breeds
Size doesn’t always determine a dog’s effectiveness as a security measure. Some small breeds can be excellent watchdogs due to their alert nature and tendency to bark at unfamiliar sounds or people.
Chihuahuas, for example, are known for their protective instincts and loud barks that can deter intruders. They’re often more attentive to their surroundings than larger breeds.
Conversely, some large breeds may not be ideal for security. Great Danes, despite their imposing size, are often too friendly to be effective guard dogs.
Aggression vs Protective Instincts
Aggression is not a desirable trait for home security dogs. Well-trained guard dogs should be protective without being unnecessarily aggressive.
German Shepherds are often praised for their protective instincts. They can distinguish between threats and normal situations, making them reliable security dogs.
Pit Bulls are sometimes perceived as aggressive, but their temperament largely depends on training and socialization. A well-trained Pit Bull can be an effective deterrent without posing a risk to family or friends.
Breeds like Golden Retrievers, while friendly, can still serve as deterrents due to their size and bark. Their presence alone may discourage potential intruders.
