This isn't just a bout hole often. There's also the question of how far. What kind of dog is he? Dogs that don't get walked can develop issues. Like barking all the time and being restless. How is your dog? Happy? Bored?

it depends what kind of dog he is and how he is. I walk our dog twice a day, a mile each time. But he's only 5 and he's a big dog. So he needs his exercise.
