I am so sorry to hear that. That must have been a terrible situation. I hope your dogs don't do it again.

My dog is like that also. I let him out in the backyard to run around. But then I go back outside to get him and he is gone! I search and search and I cannot find anyway for him to get out. So one day I watched him threw the window and what do oyu know he somehow opened the gate even though it was shut. How strange.
