Tethering dogs as a primary confinement method causes significant suffering and is associated with increased aggression, frustration and medical problems.
Chronic dog tethering causes profound welfare harm through physical restriction, social isolation and frustration of natural movement. Dogs tethered continuously cannot flee threats, cannot engage in normal exploratory behaviour and often develop severe anxiety and redirected aggression. The frustration of being restrained within sight of freedom is a recognised cause of learned helplessness and aggression. Medical harms — embedded collars, muscle atrophy, exposure injury — compound the psychological harm. Tethering as a primary confinement strategy is incompatible with basic dog welfare and should be replaced by secure fencing or appropriate indoor housing.
