I'm so sorry to hear about your ordeal and can understand the fear of it happening again.

Frankie's an escape artist and has gotten out more times than I care to admit. Her collar stays on her 24/7. She's gotten herself in some weird positions and hasn't hooked her collar yet. She is supervised whenever in the yard, so I will keep my fingers crossed. In her case though, not having tags is a bigger fear for me.

**edit* I just saw the break away collar that was linked in the thread. It looks like a great idea and a good option to not having a collar at all.
