Dog door satisfactorily installed. The pit (my brain surgeon) figured it out the second pass through, and happily came in, where I had a handful of treats, only to turn around and go out immediately and come back in for more treats. She did this about six times in the space of a minute, clearly showing the catahoula (our air head) how to do it. But Poppy is shy, and so far has to be pushed through or will travel that space on Cinnamon's heels, with Cinnamon pushing the flap for her. She'll forget to worry and figure it out eventually. This should make them a lot more comfortable in there now.
