The same, but wildly different: how the terrier breed umbrella covers glorious variety as well as shared traits

Terrier breeds: five Jack Russells

There are 33 breeds with the name terrier registered with the UK Kennel Club, although a handful fit under other groups such as toy, utility and working dogs. It may come as a surprise that only two terriers feature in the top 15 most popular dog breeds in the UK, because they typically make a fabulous all-round pet and loyal friend.

There are common traits to the group, but also huge variety in their characteristics. While we may think of terriers typically as small, tough dogs, and this stature does dominate the group, there are a few toy terriers, a couple of medium-sized breeds and even a large – the Russian Black Terrier, a relatively new working breed developed by the Russian army as a specialised guard dog, with one of his duties to round up fugitives. And a couple are terriers by name, but not by nature, including the Boston Terrier. This fits in the Utility dog group, as it has non-sporting origins. Although it is said to be a cross between the bulldog and English White Terrier, it doesn’t behave like a typical terrier and is far more at home in its owner’s company, often in urban situations such as the eponymous Boston, than down a badger hole!
