Exercise and play
Can too much exercise hurt a puppy's joints?
Last updated 23 September 2026 · How we write and check this
Short answer
Growing puppies need appropriately managed exercise. PDSA advises avoiding excessive or high-impact activity while bones and joints mature, including sustained running and demanding hikes. This does not mean eliminating normal activity. Balance manageable walks, play, training and rest, and get veterinary advice about the individual puppy rather than relying on a five-minute age formula.
Distinguish ordinary activity from forced effort
An exploratory outing with pauses differs from keeping pace beside a bicycle or repeatedly jumping for a ball. Consider the movement and intensity, not just how long the session lasts. An excited puppy may keep going without resting, so supervision remains necessary even during self-directed play.
Avoid a universal maturity deadline
Size and development vary, and a general age estimate cannot confirm that an individual puppy is ready for sport. Ask your vet before introducing demanding exercise. A generic growth curve, apparent adult height or enthusiasm is not a substitute for that assessment.
Respond to discomfort rather than training through it
Stop an activity if the puppy seems uncomfortable or reluctant to continue. Record what happened without diagnosing a joint condition yourself. Veterinary advice is needed for limping, painful movement or an unusual gait; do not assume it is merely normal tiredness or wait for a set number of days.
Key takeaways
- Match activity to the growing individual.
- Avoid forced and repetitive high-impact exercise.
- Pain or limping needs veterinary advice.
