Runty has a history of concerning behavior toward another dog in his previous home, including multiple incidents of clamping onto the other dog’s ears and not releasing; the exact triggers remain unclear. He has demonstrated the ability to disengage with verbal redirection, returning when called with relaxed and friendly body language. Runty previously lived in a high-energy, somewhat unpredictable household, which may have contributed to his difficulty regulating excitement. Around children, he becomes highly stimulated—jumping and vocalizing—and struggles to settle, despite appearing social and friendly.
