While all dogs have the potential to nip and bite, some breeds have stronger bites than others due to their powerful jaws, large teeth and fearless character.

When researching dog breeds, it's important to remember the factors that contribute to biting incidents, such as anti-social behaviour by irresponsible owners who train their dogs to be aggressive. Many dogs have been bred specifically for their intelligence and strength, while others may simply be the result of poor ownership.

To help us understand more about the dogs who bite, Norfolk-based animal behaviourist and trainer, Sarah-Jane White, has measured the strength of dogs by looking at the pounds per square inch (PSI) for each breed.

Take a look at the full list of dog breeds below...

1. Cane Corso

This Italian mastiff breed, that can weigh up to 50kg, is traditionally used as a guard dog. Sarah-Jane White says: "The Cane Corso is a breed that is known for its power and strength. With a bite force of 650 PSI, this breed can take down prey much larger than itself."

While owning a Cane Corso is legal in the UK, the increasing presence of the breed as a 'status symbol' is raising alarm among dog behaviour experts, who are worried it may pose a threat to the public.

2. German Shepherd

"The German Shepherd is well-known for its strength and intelligence," says Sarah-Jane. "With a bite force of 238-291 PSI, this breed is often used for law enforcement, military and protection. German Shepherds are also popular as family pets due to their loyalty and obedience. They are the eighth most popular dog in the UK."

"The American Pit Bull Terrier is a breed that is known for its strength and determination. With a bite force of 240-330 PSI, this breed can definitely bring down larger prey," Sarah-Jane explains.

"Pitbull terriers are legal in the United States. But in Canada, pit bulls are banned in many towns and cities. Puerto Rico had a two-decade ban in place until 2018 when it was once again made legal to own, sell and import the breed. They are banned in the UK."

6. Mastiff

"The Kangal Shepherd is a Turkish breed of dog that is known for its large size and impressive strength. With a bite force of 743 PSI, this breed is the undisputed king of the canine world when it comes to raw power. Typically used to protect against wolves, bears, and jackals in its native Turkey due to its intimidating size and capabilities as an effective guardian.

"While all of these breeds are incredibly strong, the Kangal takes the top spot as the dog with the strongest bite in the world. With a force that is more than three times that of an average dog, this breed can take down prey much larger than itself. So, if you are looking for a dog that is not only powerful but also fearless, the Kangal is the breed for you!"

Dog attack prevention tips

Understanding dog behaviour is key to keeping yourself and your loved ones safe. These include:

1. Pay attention to a dog's body language. Signs of aggression include raised fur, growling, bared teeth, stiff posture, and direct eye contact. If you notice these signs, proceed with caution and give the dog space.

2. Always respect a dog's personal space, especially if it's unknown to you. Avoid reaching out to pet a dog without permission from the owner, and teach children to do the same.

3. If you encounter a dog you're unfamiliar with, approach slowly and calmly. Allow the dog to approach you first, and extend a closed hand for them to sniff. Avoid sudden movements or loud noises that may startle the dog.

4. Stay calm and move away slowly. If a dog appears aggressive or threatening, avoid making direct eye contact or aggressive gestures.

5. Train your dog properly to reduce the risk of aggressive behaviour. Enrol them in obedience classes and expose them to various environments and people from an early age.

6. Monitor your own dog's behaviour and intervene if you notice signs of aggression or discomfort. Seek professional help from a veterinarian or animal behaviourist if needed.
