Caryn Lizwrote a review of Ruffwear Knot-A-Collar Dog Collar on December 17, 2014
Familiarity: I've used it several times
I wanted to love this collar so badly. I got it to match the Ruffwear leash which is AMAZING! Sadly, the collar is not.
It loosens easily, and my dog quickly figured out how to slip the collar while out on a walk one day, running across the street towards other dogs. It was very scary, but we are alright. My advice, if you just use it for looks around the house, then go for it. If you want to hook a leash to it, I would look somewhere else.
