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 the so-called ‘velcro dogs’.
These are the breeds that just love to be around their owner - so much that they might suffer psychologically if left along too often.
If you want a pet that will snuggle up to you and make you feel like the most important person in the world then they can be perfect.
Just be aware that your social life might suffer as long nights in on the couch will be their favourite Friday ‘out’.
Here are 12 classic velcro dog breeds.

9. Pug
One of the potential issues with velcro dogs is that the deperate need to be with you can lead to seperation anxiety if they are left alone too often - sometimes leading to destructive behaviour. That's the case for the lap-loving Pug so, if you want a breed you can leave alone for a few hours, you should maybe miss this dog off the list. | AFP via Getty Images
10. Shih Tzu
Shih Tzus are affectionate lapdogs that were bred for companionship. These sticky wee characters bond strongly with their people, and want to be as close to them as physically possible. Whether cuddling up on the couch or following you around as you do the housework, they are pretty much made of glue. | AFP via Getty Images
11. Bichon Frise
Cheerful, affectionate, and playful, Bichons thrive on being near their families. They love constant attention and quickly grow attached. These fluffy companions prefer shadowing their people over spending any time alone. | AFP via Getty Images
12. Dachshund
Ask any Dachshund owner and they'll tell you how much their pets being left alongs. These sausage dogs' favourite place is to be on their mum or dad's lap and they would very much like to join you wherever you are going. Leave them by themselves and naughtiness may well ensue... | AFP via Getty Images
