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.
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.
Different breeds of dog also tend to have very different personalities – with some dogs wary of strangers and happiest staying at home with their family.
Others are happy to get on with everybody – both human and canine – and thrive on meeting new people and making new friends.
Here are the 12 most naturally sociable breeds of dog.

12. Poodle
All three sizes of Poodle - Standard, Miniature and Toy - are equally sociable. In fact, the only way to make a Poodle more sociable is by breeding it with a Labrador or Golden Retriever, creating the super-sociable Labradoodle and Goldendoodle. | AFP via Getty Images
