I personally use the flat nylon collars with the snap on it, mainly because of the quick release snap. I prefer to have that extra bit of leeway incase the dogs collars get caught on something and need to get out of it quickly. Also because of the agility that I do (dogs run naked, no collars) I like something that can be put on and off without alot of hassle. The two bigger dogs both have the tag pockets on their collars, which is great for stopping the noise and also for Winter trying to chew on them.

The thing with the nylon collars is to make sure you get one that's not only the right size around the neck, but the right width as well. Tama couldn't wear the same width of collar as Smudge, and even Winter doesn't always have one that's the same width either.
