I am hoping to eventually buy some land (at least 4 acres) outside the city, and I plan on adopting a bunch of "undesirable" (seniors, "bad" breeds, ugly, unfriendly, etc) dogs. They would be indoor pets, but I would have a doggy door for them to come and go as they please when I am not at home.
Obviously I would likely poop scoop close to the house, but I don't want to have to worry about most of the property.
What is the minimum amount of land I would need for 1 average sized dog, to not have to poop scoop? Is half an acre (roughly 1/3 of an NFL field) per dog enough?
A few sub-questions:
How would your answer change if the land was forested vs if it was dirt or grass?
What about climate? I live in northern Virginia; we have "normal" seasons.
Would their diet change the equation?
Note: Ignore any laws you might know of regarding poop scooping, or any environmental impact from poop. You can assume I will follow all local laws, yadda yadda yadda...
