Annie has just finished a crazy dog session in the yard and is now waiting on the deck, at the gate, for me to let her inside the house.
Whenever she wants go inside her practice is to run up the steps and body slam the gate.
If it's latched and doesn't open she simply crawls through the boards - which is what she did here.
It works the other way too, except she knows not to body slam it from the other direction.
