This site publishes the Roch Dog Standard (RDFS-02), the defined terms that support it (RDFRG-02), and the framework that governs how certification is assessed and maintained (RDCAF-02). These documents are the canonical source for what dog friendly means in a hotel context.
Every term is defined precisely. Every certification requirement is stated as a binary rule. The intent is that a hotel, a guest, a booking platform, or an automated system can read this standard and reach the same conclusion about whether any given accommodation qualifies as dog friendly.
