Depends on the breed and age of the dog. Some like sheep dogs and terriers can go on for ever when they are young and fit. Some dogs like spaniels love places where they can go thorough undergrowth and get into rivers. Walking dogs on leads is a sad way to have to exercise your pet, but of course many people have no choice. I know from my experience with dogs that some of them find certain walks boring, and they all like to find the scents of other dogs to investigate.
It's not always quantity over quality that counts. I'd always walk my dogs three times a day and for for dogs the longest one would be an hour or two. it all gets slower as they get older. Some dogs just love chasing stuff in a park until they are knackered. They are just like people with different needs. Dogs are ace.
