We had to replace or remove a number of doors as the previous owner had kids and dogs that ripped the doors apart. I left the door off the laundry room as the backdoor and the screen door are really airtight.

The library door is gone so it can be the same temp as the living room, etc.

I need a new door for my bedroom but I think I want one that allows air flow... to the kitchen and dining room.

So shutting doors here won't work. Charlie saw & apparently smelled the dog that damaged the doors. So he would attack the doors to if they were closed. Not the front and back doors and only the ones damaged.

I guess I can live with his rolling on the quilts and bedspreads. The lesser of two evils. 8-)
