Dogs come in all shapes and sizes - the Royal Kennel Club (formerly 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.
Each has its own list of positive and negative attributes, and it’s important to take plenty of time to think about what breed will fit into your lifestyle the best - for instance a smaller dog if you live in a flat, or a hypoallergenic dog if the mere mention of dog hair makes you think about sneezing.
There is even scientific research to guide you, in particular psychologist Stanley Coren’s groundbreaking book The Intelligence of Dogs.
Of course some dog breeds are simply more popular than others - and there’s usually good reason for them to be picked by more human families than any other.
So it’s worth considering them seriously if you are looking to add a four-legged friend to your household.
Each year the Royal Kennel Club publishes data showing how many of each breed was registered with them - and they’ve just published the figures for 2025.
Here are their 12 top dogs, starting with the most popular.
