Mental health welfare for companion animals — preventing boredom, anxiety, and cognitive decline — is an increasingly recognized dimension of responsible pet ownership.
Companion animal mental health encompasses preventing negative states like boredom and anxiety while actively promoting positive experiences like curiosity, play, and social connection. A dog left alone for 8 hours in a bare room is not physically ill but is suffering. Mental health welfare requires active management — enrichment, training, social opportunities, and veterinary attention to behavioral changes that indicate psychological distress.
