Almost every hotel that takes a dog calls itself pet friendly, and until October 2026 nobody had defined the phrase. That month the International Journal of Hospitality Management published the first academic definition of pet friendly, by Nikolaos Iason Koufodontis of the University of the Aegean, built from a review of the whole field and a survey of 1,041 people in 66 countries. This paper reads it for the people who run hotels.
People agree on the core. What turns a hotel that allows pets into a hotel that is pet friendly is everything around the permission: the right facilities, clear rules, staff who know what they are doing and the basic amenities. Nine in ten would call a hotel pet friendly if it admits the pet, says plainly what its rules are and provides the basics.
They disagree at the edges, and the edges are where a hotel loses guests. Only 12% would call a hotel pet friendly if it allows dogs under 10 kilograms but not cats, and only 11.7% if it advertises as pet friendly and then charges a very high fee. The paper separates rules, which govern how a pet behaves inside the welcome, from restrictions, which decide who is welcome at all, and closes with what a hotel should do and where the Roch Dog Friendly Standard sits against the definition.
