Modern animal welfare science focuses not just on preventing suffering but on enabling animals to experience positive states including joy, curiosity, and social connection.
Traditional welfare frameworks focused on preventing the five freedoms violations: suffering from hunger, discomfort, pain, fear, and distress. Modern welfare science recognizes that absence of negative states is insufficient — animals should also have opportunities to experience joy, curiosity, social bonding, and play. A dog with adequate food, shelter, and veterinary care may still have poor welfare if they spend most of their time alone and bored. The positive welfare framework transforms what constitutes adequate care from minimum standards to genuine flourishing.
