If you live in the city and work all day, you probably can’t have a dog. But when you go for a walk in the country, wouldn’t it be great to have a friendly dog walk with you and fetch sticks and leap around and do all sorts of dog things ? Enter dog rentals.
At the start of major walking trails a dog rental business could setup. In the same way you can rent horses, you could rent dogs. They would have to be a friendly easy going breed that loves company, maybe golden retrievers ? The walkers get a friend to walk with and a more enjoyable walk, the dogs gets loads of walking and affection, and you get income.
