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.

1. Poodle
No matter which size of Poodle you go for - Standard, Miniature or Toy - these immaculate dogs tend to stay in good health, with a lifespans of up to 18 years. Only older dogs tend to develop the joint and eye issues common to the breed. | Canva/Getty Images
2. Australian Cattle Dog
A relatively rare breed in Britain an Australian Cattle Dog called Bluey made it into The Guiness Book of Records as the world's oldest dog. He reached the amazing age of 29. While longevity and health don't always go hand-in-hand, the breed are known to stay fairly fit until a ripe old age. | Canva/Getty Images
3. Havanese
Hailing from the capital city of the Carribean island of Cuba, like many small dogs the Havanese has more chance of developing liver and kidney disease than their larger cousins. Otherwise these loving characters can be expected to remain healthy for most of their lives. | Canva/Getty Images
4. German Pinscher
The German Pinscher is not known for any particular breed-specific health conditions, other than the usual eye and hip complaints later in life. Regular excercise and proper care should lead to a long and healthy doggy life for these born entertainers. | Canva/Getty Images
