All of our dogs have super nice indoor and outdoor runs. They have the freedom to be in or out when they want to be. There indoor area is a 4 X 4 & the outdoor is a 4 X 12. We free feed here 100% and soon our automatic waters will be in (this will be great as the dogs will have fresh water 24/7). Our indoor pens are all custom made by my husband & they are one piece. All indoors of this “Dog House” are covered with Epoxy. You can see the big furnace with a huge heating a cooling duct, heating is by Natural Gas. We have a dual thermostat system, as we keep the nursery warmer. Every pen always has a rawhide chew, ball and toy. They all have Pipe Dream beds to lounge on, in the Winter we put fleece covers on them all. My dogs also have a big turn out they play in nearly everyday, 100 X 75 which goes almost around the whole building.
