If you’ve been thinking about getting a new dog then you’re not alone – Royal Kennel Club (that’s the new name for the UK Kennel Club) figures show that the number of people looking for puppies has surged to record levels over recent years.
Dogs come in all shapes and sizes - the UK Kennel Club recognises 221 different pedigree dogs, from Affenpinscher to Yorkshire Terrier (there are sadly no dog breeds starting with the letter ‘z’!).
Then there are all manner of crossbreeds, from so-called ‘designer dogs’ to lovable mongrels.
So 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 an easy to train dog.

Before they were domesticated, dogs had to fight for everything from food to territory – so signs of aggression were essential to their survival.
Many of these has been bred out to create the perfect family dogs we know today, but some breeds are more likely to retain an aggressive side than others.
There can be good reason for this – for example for those used as service or guard dogs – but prospective owners should be aware that this is the case before choosing to welcome a certain dog into their homes.
It should also be said that individual dogs may display attributes that are unusual for their breed, and all dogs have the potential to be aggressive in certain situations.
Here are the 10 breeds most likely to show aggression – including growling, snarling and snapping.

7. Rottweiler
While the Rottweiler's reputation for uncontrolled aggression is slightly unfair, it is a breed of dog that has the potential to be aggressive.

8. German Shepherd
Aggression isn't always a bad thing in a dog - the German Shepherd's temperament means that it excels as a forces dog, police dog and guard dog. While it's not a dog to get on the wrong side of, if the aggression is channelled in the right way it can be a great pet that is sure to protect its beloved family. | Canva/Getty Images
