i appreciate your reasoning for keeping each dog in his own cell. but, my grandfather used to keep his pack of fox hounds in one common pen and used one common house. he had one pen for grown dogs and one pen for pups and young dog. he had several dogs in each pen. it was a long time ago, i was just a teenager at the time, but i don't recall him ever having a problem. i was his unpaid servant. i cleaned the pens, de-ticked the dogs after each outing, drove the willis (like a jeep suv), and helped with the loading and unloading of dogs. i can't explain why or how he got by with this set up. we, my familly, also had a common pen with a common house with several hounds and didn't have a problem. if i were to build a kennel, i would have individual cells.
