There's so much to consider when you decide to welcome a new dog into your home - from their energy levels to their physical maintenance and if they get on well with kids. It's also important to remember that some breeds are more intelligent than others, and will therefore be more likely to follow your commands.
A new study conducted at the University of Helsinki in Finland has revealed the world's cleverest canines after examining 13 breeds, from the Belgian Malinois to the English cocker spaniel. The research put 1,000 dogs to the test and ranked them in a series of 10 cognitive and behavioural challenges.
