Hoopie Collar - Ruffwear
There's not a whole lot to say about a dog collar, but this one is certainly the best one we've owned / used. It's sturdy, but lightweight. The V-ring is attached in such a way that it doesn't stress the plastic buckle which holds the collar in place (note that on a previous collar this plastic buckle ultimately failed and would pop open when pulled hard which was pretty inconvenient). We put on our own ID tag, but it fitted the Quick Clip easily. It's easy enough to adjust the size of, and stays set without slipping once adjusted. Essentially this lives on our dog 24/7 and he has no issues with it.
