The study, which surveyed 12,000 people about their happiest staycation memories, also found that more than 40 per cent of bookings through the site in the past year included dogs.
The North West Highlands topped the list with a dog-friendly super score of 14.36 out of 15, followed by Cumbria with 14.09 and Northumberland with 13.92.
The rankings were based on suitability, outdoor spaces, and walkability.
Sarah Pring, digital PR manager at holidaycottages.co.uk, said: “Joy for our four-legged friends can be found in so many places – whether it’s bounding through the waves on a sandy beach, exploring woodland trails with their tails wagging, or curling up by the fire after a day of adventure.”
Cumbria was praised for its varied walking trails, from gentle lakeside paths to challenging mountain hikes, all set within the Lake District National Park.
Northumberland, which placed third, was highlighted for its dog-friendly beaches and national park, as well as welcoming eateries and historic sites like Bamburgh Castle and Cragside, which allow dogs in certain areas.
