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.
One thing to take into consideration is that some dogs simply can’t handly the heat.
These breeds will quickly tire – and even become ill – if they are exposed to hight temperatures for an extended period of time, so won’t thank you for long walks in the sun and don’t enjoy living in warmer climes.
Here are the 12 breeds of dog that hate the heat.

12. Boston Terrier
