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.
Meanwhile, some will want a dog that has a calming influence on their home and family – avoiding more hyper breeds like Border Collies and Springer Spaniels.
Here are 12 of the most chilled dogs.

6. French Bulldog
The French Bulldog is currently challenging the Labrador Retriever for the title of most popular dog breed in the UK. Their calm temperament makes them great companion dogs, while they'll also enjoy making new friends - both doggy and human - at the park. | AFP via Getty Images
7. Great Dane
Despite their ginormous size, Great Danes are famously calm and gentle. These genuine gentle giants tend to be content lounging indoors for the most part, making them surprisingly easy to manage with minimal exercise. | AFP via Getty Images
8. Clumber Spaniel
Equally happy as companion or hunting dogs, the American Kennel Club desribes the Clumber Spaniel as making "esteemed housemates". They are reliable, thoughtful, affectionate and calm in nature. | Canva/Getty Images
