Matching exercise provision to breed requirements is fundamental to dog welfare; exercise deficits and excess both cause significant welfare harms.
Dogs denied adequate exercise experience frustration, anxiety, and boredom that manifest as destructive behaviour, excessive barking, and anxiety disorders. Working breeds in low-activity households frequently develop compulsive behaviours. Conversely, puppies exercised too intensively on hard surfaces develop growth plate injuries. Brachycephalic dogs exercised in heat suffer respiratory emergencies. Matching breed to lifestyle before acquisition prevents both owner surrender and chronic welfare harm.
