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.
And one thing you might like to consider is that some breeds tend to stay healthier for longer, meaning your vet bills shouldn’t be too painful and your pet has a better chance of a pain-free and lengthy life.
The Labrador Retriever, for instance, may be the world’s favourite dog, but they are predisposed to ear, eye and joint problems.
Here are 12 of the healthiest dog breeds.
