When it comes to choosing a dog, temperament matters just as much as size or appearance. While any dog can bite if provoked, scared, or poorly trained, some breeds have a reputation—earned or not—for being more likely to nip or bite under certain circumstances. This doesn’t mean these breeds are “bad” or unlovable.
In most cases, biting behavior is more about environment, training, and handling than genetics. Still, it’s helpful to be aware of which breeds may require extra socialization, consistent training, and close supervision around children or strangers.
Here are 10 dog breeds known for biting—along with a little context on why they’ve earned that reputation.
Chihuahua
Small but mighty, Chihuahuas are often underestimated because of their size. But don’t be fooled—these tiny dogs can have a big attitude. Chihuahuas are fiercely loyal and can become snappy if they feel threatened or overstimulated. Their bites aren’t likely to cause major damage, but they can surprise people who assume they’re all cuddles and cuteness.
Dachshund
Yes, those little “wiener dogs” have a history of biting. Originally bred to hunt badgers, Dachshunds are braver than they look and can be quite territorial. If they’re not properly socialized, they may lash out at strangers or other animals, especially if they feel their space is being invaded.
Jack Russell Terrier
These energetic pups are incredibly smart and driven—but also known for being feisty. Jack Russells can be stubborn and may bite out of frustration if they aren’t getting enough mental stimulation or exercise. Without proper training and outlets for their energy, they can become nippy.
Cocker Spaniel
It may surprise some people to see this sweet-faced breed on the list, but Cocker Spaniels have one of the highest recorded bite rates among family dogs. This is often due to poor breeding practices, a condition called “rage syndrome” (rare but real), or anxiety and stress. Early socialization and positive reinforcement training are key.
German Shepherd
Loyal, intelligent, and protective, German Shepherds are often used as police or military dogs—but that same protective nature can lead to biting if the dog feels its family is in danger. Poor training or inconsistent handling can also contribute to aggressive behavior. With proper guidance, however, they’re among the most trainable breeds.
Rottweiler
Rottweilers are strong, confident dogs with a natural instinct to guard. In the wrong hands, this can lead to aggressive tendencies and biting. But with consistent training, socialization, and strong leadership, Rottweilers can be calm, affectionate, and safe companions.
Siberian Husky
These gorgeous dogs are known for their wolf-like appearance and playful personalities—but they can also be a handful. Huskies are independent, high-energy, and sometimes unpredictable. They don’t respond well to harsh discipline and may bite if they feel cornered or confused.
American Bulldog
Muscular and protective, American Bulldogs can be loving pets but require firm, experienced handling. If not properly trained and socialized from a young age, they may become territorial and prone to biting. Early training is essential to help them understand boundaries.
Pit Bull-Type Breeds
Pit Bulls are perhaps the most controversial dogs on this list. While they are not inherently dangerous, their strength and tenacity make bites more severe when they do occur. Many bites result from abuse, poor training, or being used for illegal fighting. In a stable home with proper care, Pit Bulls can be gentle, loyal, and even great with kids.
Akita
Akitas are powerful, independent dogs originally bred for hunting and guarding. They’re known to be reserved with strangers and can be aggressive toward other animals if not socialized early. Their dominant nature means they’re best suited for experienced dog owners.
