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.
Conversely certain breeds are predisposed to certain health conditions which, in some cases, may shorten their life.
This doesn’t mean that they don’t make great pets – in fact some are amongst the most popular and loved dog breeds in the UK – but it’s important to know that there are potential issues so you know what symptoms to look out for so you can make sure your pooch gets the best possible early treatment.
Here are the 24 most and least healthy dog breeds.

9. Siberian Husky
Given they've been bred to pull sleds over long distances in sub-zero conditions, it's perhaps not surprising that a Siberian Husky will tend to remain healthy as a family pet. While some individual animals will suffer from eye and hip issues, they are unusual early in life. | Getty Images

10. Basenji
A breed of Central African origin, the Basenji is famous for being a dog that doesn't bark - it makes a slightly odd yodelling noise instead. Bred to hunt prey, as long as they get enough exercise they have no real predisposition to developing any health problems. | AFP via Getty Images
11. Airedale Terrier
Also known as the Bingley Terrier, the King of Terriers or the Waterside Terrier, the Airedale Terrier is a breed that was first bred in the West Riding of Yorkshire. It's a dog a relatively low number of health concerns, with cancer being the leading cause of death. | Getty Images for Westminster Ken
12. Greyhound
Fast, lazy and healthy are the three dominant traits of Greyhounds. The general rule is the larger the greyhound, the more likely they are to develop muskoskeletal conditions - so Italian Greyhounds are least likely to need a vet visit - but in general they stay in tip-top condition until they get old. | Canva/Getty Images
