Ideally what do you think is the set amount of time that you should walk a dog every day? I think lack of exercise is one of the biggest issues that dogs face. I know there are some owners who walk their dogs every day to let the dog 'do its business' but that's not the same thing as a long exercise session. Do you think exercising a dog three times a week is okay, or should it be done more frequently than that? It's great that dog walking services exist and cater to people who want their dogs to get enough exercise, but I think dogs need to run and play regularly too, not just get walked.
