I wasn't expecting Lizzy, wasn't expecting to keep her after I got her and never knew about YTs having to have harnesses. Luckily she has never so much as coughed or made a choking sound.
In agility, anything but a plain, no tags, no adornments, collar is considered a safety hazard. Also, that is all you can have on your dog when you run them. I use hound collars or martingales, and since they aren't allowed, I run naked dogs.
