In Berlin, pets ride public transport; in Barcelona, restaurants offer pet menus; Dutch companies promote "bring your pet to work" policies. Europe is transforming "pet-friendly" into a measurable standard of urban competitiveness.

Systematic certification encompasses four key dimensions: public transportation accessibility, pet admission rates in commercial venues, housing and workplace policy protections, and community pet cultural activities. Data shows that for every 10% increase in pet-friendliness index, settlement willingness among young families grows by 7%, community interaction rises by 18%, and night street safety perception improves by 23%.

This represents more than mere convenience—it reflects an evolution in urban governance. When cities provide equitable space for pets, they demonstrate respect and inclusivity for all living beings.

Pet-friendliness is not an added service but an essential gene of modern livable cities. The warmth of a city is truly measured by how it treats its quietest residents.
