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.

1. Basset Hound
The Basset Hound is famous for being able to follow scents without getting distracted, and remaining calm while doing so. This calmness also applies to all other parts of their personality. They will develop a strong relationship with their owner, although some patience is required for their training. | Getty Images
2. Bergamasco Sheepdog
The striking Bergamasco Sheepdog is described by the American Kennel Club as being "bright, loyal, protective, and among the more calm dog breeds". Their showy coat needs surprisingly little grooming, so they are low maintenance too. | AFP via Getty Images
3. Tibetan Spaniel
The Tibetan Spaniel has a calming and gentle - yet playful - temperament. Don't let their relaxed demeanor fool you though - they also make for tough competitors in dog sports like agility, rally and obedience. | Getty Images for Westminster Ken

The gentle Cavalier King Charles Spaniel is known for its friendly and calming disposition. It makes them a chilled presence in any household - and suitable pets for young and old alike, happily curling up in their owners' laps for hours. | AFP via Getty Images
