How much exercise does my dog need? Build a day plan for their age and energy

Vets and welfare groups don't give one number of minutes for dog exercise: it depends on age, size, breed, health and weather. The PDSA and Kennel Club say at least one to two walks a day, and some breeds need an hour or more.

Enter your dog's age, energy, the weather and any health worries, and get a starting-point day plan with walks, brain games and rest, plus what the sources say about puppies and when to ask a vet.
