Dog Breeds That Guard Picnic Tables From Stray Cats
1. German Shepherd

Height: 24–26 inches (male), 22–24 inches (female)
Weight: 65–90 pounds (male), 50–70 pounds (female)

The German Shepherd is not only one of the most recognized guard dog breeds, but also one of the most versatile dog breeds in the world. While they are best known for their police and military work, these dogs have also excelled in roles like search and rescue, service dogs for people with disabilities, and even in acting roles on screen.
These herding dogs are confident and alert, often forming a deep bond with their owners. Though naturally protective, German Shepherds are not unnecessarily aggressive—they simply have a natural instinct to assess situations and protect when needed.
German Shepherds also enjoy having a task. Whether it’s guarding picnic tables from stray cats or participating in structured dog sports, they thrive when given responsibility. Their intelligence demands not just physical outlets, but also regular mental stimulation, such as puzzle toys, tracking games, or advanced obedience routines.
2. Rottweiler
Breed Group: Working
Height: 24–27 inches (male), 22–25 inches (female)
Weight: 95–135 pounds (male), 80–100 pounds (female)
Lifespan: 9–10 years
The Rottweiler is a powerful and confident working dog, descended from Roman mastiffs and refined in Germany as a herder and protector of cattle. Purina states that they earned the nickname “butchers’ dogs” in Rottweil for driving livestock and guarding butchers’ earnings, thanks to their muscular build and fearless presence.
Despite their intimidating look, Rottweilers are deeply affectionate with their family and can be gentle and playful with kids when properly trained from an early age. These dogs are very intelligent and highly trainable, though they do best with experienced dog owners who provide strong leadership and structure.
Rottweilers thrive when they have a purpose. They enjoy activities that challenge both their body and mind, including obedience training, dog sports, and even guarding picnic tables! Regular exercise and consistent routines are essential for this breed to stay balanced and well-behaved.
3. Doberman Pinscher
Breed Group: Working
Height: 26–28 inches (male), 24–26 inches (female)
Weight: 75–100 pounds (male), 60–90 pounds (female)
Lifespan: 10–12 years
The Doberman Pinscher was originally bred by a German tax collector named Louis Dobermann, who needed a strong, alert, and loyal dog to accompany him on his rounds. The result was a sleek, muscular breed with sharp instincts and a powerful presence. Today, the Doberman has evolved into a loving family companion that is still known for being one of the best guard dogs around.
Dobermans are known for their intelligence, loyalty, and ability to learn quickly. They are extremely loyal to their owners and often form tight bonds with their family. With proper socialization and obedience training from an early age, they grow into calm and well-adjusted pets who are also watchful and ready to protect when needed.
Although often misunderstood as aggressive, modern Dobermans are generally friendly, sociable with humans and other dogs, and enjoy being involved in family life. Their confident nature and alertness also make them great for unique roles, like helping to guard picnic tables from stray cats with little more than their presence.
4. Bullmastiff
Breed Group: Working
Height: 25–27 inches (male), 24–26 inches (female)
Weight: 110–130 pounds (male), 100–120 pounds (female)
Lifespan: Around 10 years
AKC says that the Bullmastiff earned the nickname “Game Keeper’s Night Dog” for its historical role in quietly stopping poachers. With its imposing size and steady presence, this breed is naturally one of the excellent guard dogs, capable of deterring threats without aggression.
Although powerful, Bullmastiffs tend to be gentle giants. They form strong bonds with their family and live up to the reputation of loyal companions. Careful socialization from an early age teaches them to adjust to other animals and invited guests.
Bullmastiffs are surprisingly low-maintenance in terms of exercise. Canine sports aren’t a must, though calm, structured play and daily walks help keep their mind sharp. They aren’t suited to cold weather for long periods, due to their short coat and heavy build. This breed is also relatively easy to train, especially when positive reinforcement methods are used consistently.
5. Great Pyrenees
Breed Group: Working
Height: 27–32 inches (male), 25–29 inches (female)
Weight: 100 pounds and up (male), 85 pounds and up (female)
Lifespan: 10–12 years
The Great Pyrenees is a noble and strong large dog that was bred to guard farm animals in mountainous regions. Known for their calm nature and impressive size, they are natural protectors and often work independently with confidence and purpose.
Their signature thick coat helps shield them from harsh weather and gives them a majestic, fluffy appearance. Though beautiful, it does require regular grooming to stay clean and healthy.
With the right guidance, Great Pyrenees can live peacefully with many dogs and livestock. However, their independent mindset means they need proper training from an early age to establish boundaries and encourage cooperation with their owners.
Because they were raised to patrol wide areas, they enjoy being off-leash in safe, enclosed environments. When not working, they are known to be gentle and devoted, making them excellent companions for families who can meet their needs.
6. Staffordshire Bull Terrier
Breed Group: Terrier
Height: 14–16 inches
Weight: 24–38 pounds (males), 24-34 pounds (females)
Lifespan: 12–15 years
The Staffordshire Bull Terrier is a compact, muscular breed known for its grit, charm, and deep devotion to its family. Originally bred in England during the 18th and 19th centuries, this dog was once involved in blood sports, but over time, it has evolved into one of the most affectionate and incredibly loyal companions you can find.
Although small in size, the Staffordshire Bull Terrier is packed with physical strength and confidence. They are often described as courageous and strong-willed, always eager to stand their ground, especially when it comes to protecting their loved ones. Their strong character doesn’t mean they are aggressive—in fact, Staffies are famously people-oriented and thrive on close contact with their humans.
This breed has a joyful and clownish personality that makes them great for interactive play. However, they are a high-energy breed and need daily exercise and plenty of regular walks to stay mentally and physically balanced. Despite their energetic nature, they’re surprisingly well-suited for apartment living as long as their exercise needs are met.
7. Boxer

Height: 23–25 inches (male), 21.5–23.5 inches (female)
Weight: 65–80 pounds (male), females are 15 pounds less than males

The Boxer is a spirited and muscular breed known for its fun-loving nature and fierce devotion to family. Originally developed in Germany as a hunting dog, the Boxer has since earned a reputation as a playful yet watchful companion with a sharp mind and a loyal heart.
With a high prey drive, Boxers are always alert and ready to chase, making them a great pick to guard picnic tables from stray cats or even keep watch over curious sheep on a farm. While they weren’t bred to guard livestock specifically, their strong instincts and responsiveness allow them to adapt to many roles, including life around other farm animals.
Boxers are highly intelligent and thrive on structured routines and regular interaction. They enjoy challenges and pick up new commands quickly, especially when training is turned into a game. Their goofy, expressive faces and playful behavior often make them favorites among children and adults alike.
They require long walks and active play to burn off energy. Thanks to their stamina and athletic build, they can comfortably cover long distances, making them great companions for hiking or jogging.
