I've been through many collars and this one is by far my favorite: PetPDC ComfortFlex Limited Slip Collar
"Made in the USA
Fully padded nylon construction with reflective strapping. Highly adjustable, machine washable (line dry)
Smooth limited cinching action let's the collar tighten for safety, but never to the point of choking" (Amazon)
I like comfort for my dog, while being practical, safe for day/night use, and also for looks. I love this one!
They have lots of different colors to choose from. Great reviews! Here's a link if you want to see what other people think
I got mine in orange, because she is mostly black and i love the black/orange look!
