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.

1. Vizsla
It's thought that the term 'velcro dog' was originally coined for the silky-coated Hungarian Vizsla. Thase charmers just love to be in close contact with their pet parents, whether it's on the couch or on outdoor adventures, where you can be sure they'll be right by your side at all times. | AFP via Getty Images
2. French Bulldog
Every step you take, every move you make, your Frenchie will be watching you. The UK's fifth most popular pet is unlikely to leave you alone for a second. | AFP via Getty Images
3. Labrador Retriever
The UK's most popular dog for umpteen years (although it received some competition from the equally sticky French Bulldog a couple of years ago), the Labrador Retriever will rarely leave their owner's side unless forced to. On walks it's unusual for these lovable creatures to stray far enough to lose sight of their humans. | AFP via Getty Images
4. Golden Retriever
Golden Retriever What is true of the Labrador Retriever also tends to be true of close cousins the Golden Retriever - and that's the case with their general stickiness. They will tend to be very interested in everything you are doing, and keep a close eye on how you are doing it. | Getty Images
