Coronado's Aussies

We live on 40 acres where my dogs have the freedom to roam the property, the majority of the time. We do have doggie doors into our house and into the dog room in the back porch. Puppies are whelp in the house and raised there until they demand its time to be moved into the dog room (12' x 12' enclosed room) on the back porch. There is nothing like a litter of puppies barking, squealing, and playing at 3 in the morning. This is time to move tge litter to the dog room. There they have dog houses and crates as houses inside the house with a doggie door that opens up into a large 30 x 60 yard with 6 foot block wall. In increments they learn to use the doggie door and go potty outside. Once they are older, usually 8 to 10 weeks of age, I open the gate and it lets them go out into a 1/2 acre pen that is adjoining to their yard. We have several barns on our ranch, a barn dedicated to dog and the horse barn. The dog barn has 2 indoor 12' x 12' stalls and one 12' x 36' indoor stall with large fenced outruns. The horse stalls come in handy when a dog needs to be separated for whatever reason.
