Appropriate exercise is fundamental to canine welfare, but over- and under-exercise both cause welfare problems requiring thoughtful management.
Mobility welfare encompasses both the suffering caused by inadequate exercise and the injuries caused by inappropriate exercise intensity or type. Puppies of large breeds forced into high-impact exercise before skeletal maturity develop joint problems that cause lifelong pain. Brachycephalic dogs exercised in heat experience respiratory distress. Arthritic dogs not given appropriate gentle daily movement suffer from muscle wasting that worsens their underlying condition. Tailoring exercise to the individual dog's breed, age and health status prevents most exercise-related welfare problems.
