Revealed: Britain’s boom in dog ownership as 15.5 million now live in UK homes
Britain’s love of dogs is stronger than ever, with younger generations driving a structural shift in pet ownership across the UK.
Brand new figures from UK Pet Food show the UK dog population has increased by three million over the past five years. The organisation’s latest Pet Population Survey for 2026 estimates there are now around 15.5 million dogs living in UK households, up from 12.5 million in 2021, highlighting dogs’ growing role at the heart of modern life.
This growth reflects rising ownership across UK households, with particularly strong increases among younger adults.
Dog ownership has increased from 33% of households in 2021 to 41% today, with especially strong growth among younger age groups.
Among 25-34 year olds, ownership has risen from 41% to 58%, and from 41% to 53% among 16-24 year olds.
The rise in dog ownership among younger people reflects the increasingly important role pets play supporting wellbeing, shaping daily routines, and helping people feel more connected in everyday life. For many, dogs are not just companions but a central part of daily routines, from morning walks to social interactions.
Overall, as of the 2026 findings, the UK is home to around 36.5 million pets, with 62% of households – around 18 million homes – owning at least one pet, reinforcing the important role companion animals play in everyday life.
Cats remain the second most common pet, with an estimated 13.1 million cats living in UK homes, up from around 12.2 million five years ago.
Nicole Paley, Deputy CEO of UK Pet Food, comments: “We’re seeing younger people increasingly bringing dogs into their lives in a way that feels more integrated than ever before.
“For many, pets are part of how they live day to day, shaping routines, supporting wellbeing and offering companionship in a busy world. From morning walks to dinner dates and office trips, dogs are becoming part of the rhythm of everyday life.”
Animals are also a central part of family life, with more than half of households with children, 52%, owning a dog, while 39% own a cat.
