House is a 2500sq ft 2 story, plus a finished basement adding another 1000sq ft or so.
Yard is 10 acres. About 1/8 acre is fenced as the dog turn out/potty/play yard. The dogs have access to the rest of the property when we're out with them to supervise, except for the 4 acres or so that is fenced off for our horses (and the dogs have to stay out).
We have 6 GSDs, 2 horses, and 2 cats.
