Sierra - always on, unless I'm brushing her neck, then it goes right back on. (She's run away before, and the people called me after reading her ID tag)

Buddy - He looooooves a good neck scratchin' so I'll take it off, and sometimes leave it off at night because he's on night watch security duty while Sierra and I are sleeping, and walks around, and his tags make to much noise, and the princess Sierra has to get her beauty rest!!
