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 which ranks breeds by instincts, obedience, and the ability to adapt.
Meanwhile, certain breeds have particular attributes or temperaments which mean that they are less suitable for households with small children.
Here are the 12 breeds of dog that aren’t suitable for young families.

1. Weimaraner
A large and beautiful dog bred to hunt big game, the Weimaraner sometimes doesn't know its own strength and can enjoy playing rough with its human family. This is no problem when it comes to adults, but can be a problem with youngsters. | AFP via Getty Images
2. Chow Chow
They may look like big cuddly teddy bears, but Chow Chows can become annoyed by children yelling and running around - potentially responding with aggression. | Getty Images
3. Dachshund
They may look like butter wouldn't melt in their mouths, but the Dachshund is notoriously unpredictable and hard to train. When it comes to children they have little in the way of patience, and are not above giving a nip to curious little fingers. | Getty Images

4. Australian Shepherd
As the name suggests, Australian Shepherds were originally bred to herd sheep. One way they did this was to nip at the feet of the sheep, and its behaviour that they can now exhibit when young children are running around. | Getty Images
