If you’ve been thinking about welcoming a new dog into your home then you’re not alone – Kennel Club figures show that the number of people looking for puppies has surged to record levels in recent years and around one-in-three UK households now contain at least one pooch.
But with 221 different breeds of pedigree dog to choose from, there’s plenty of thinking to do before you select your family’s latest four-legged addition – whether you want a large dog, family-friendly dog, or crossbreed.
There’s even academic guidance to seek out, with Psychologist Stanley Coren’s book ‘The Intelligence of Dogs’ ranking breeds by instincts, obedience, and the ability to adapt.
Different breeds of dog also tend to have very different personalities – with some more likely to lash out with nips, nibbles and even bites.
Of course any dog is capable of delivering a damaging bite, while most dogs of any breed are unlikely to do any damage unless seriously provoked, but there are certain breeds who have temperaments making them more likely to be aggressive than others.
Researchers in the USA carried out a survey of some of the estimated five million canine bites suffered in the country each year, seperating them into types of dog.
Here are the 10 breeds of dog that they found were most likely to bite.

9. Border Collie
The Border Collie is the world's most intelligent dog breed, but they have been bred to herd and protect livestock - using their teeth if necessary. They may well give a nip while playing or exercising with their owner, but a stern word will let them know it's not acceptable. In every other way they are a loving and gentle family dog.

An unexpected entry in this list, the adorable Cocker Spaniel is unlikely to do any damage but owners will know that they often nip as puppies. The majority of adult dogs will grow out of the habit. Photo: Canva/Getty Images
