Sorry, very new at this. I had an Akita I recsued when I got the puppy. Akita had some behavior issues, but was always friendly with people. She passed away in September of this year. Katje (the problem dog) had lived with the Akita since 10 weeks old. After the Akita died we started going to daycare. We don't know how the gate was opened, maybe someone here left the caribeaner off the latch, or a neighborhood kid opened it, no idea. Both dogs got out once before, but they pushed the gate open because the latch was loose. That problem is fixed.
