VetCompanion is the first comprehensive, unbiased, evidence-based point-of-care decision support resource for veterinary professionals. It provides an elegant, simple to use, digital interface where veterinary professionals can access a single trusted resource for all their clinical and drug information needs, via mobile phone, tablet or laptop. The existing literature and guidelines for each clinical topic are synthesized, so users have instant access to the most current and well-sourced diagnostic and treatment recommendations available. Unlike any textbook, the information in VetCompanion is "organic", always expanding and updating so users have the most current, state-of-the-art information available. The rigorous methodologies employed, modeled on those used in human medicine, assign evidence ratings, so users can evaluate the strength of evidence.
