Swimming collar

My lab swims a lot and this is the only collar that doesn’t stink all the time. I love it!

This collar has been perfect

I ordered two of these in size large, one for each of my 60+ lb labs. Since they're adjustable, the sizing was perfect. I like how thin and lightweight the collar is, but it's still very durable. The dogs don't mind it at all. I know this sounds dumb but I wish there was a pink or purple color option to match the front range harness but I ordered the light blue and it's very pretty with purple accents.

Doesn't leave a mark!!

We have a golden doodle and his first collar, regular flat nylon collar was leaving a mark from.where it was on his neck and matting his hair. I was told that rolled collars would prevent that but couldn't find something I liked enough to buy. Once I found the knot a collar I fell in love with the look. Once we got it, I loved it even more. It looks great on our boy, fits perfectly, without being too tight. His collar is only used for his tags so the lower profile and the tag silencing thing is fantastic too.

Slippery Slope

I love the idea of this collar, but....the knots slip and then my dog chews through the paracord; then his tooth gets caught in the ring holding his tag. I suppose I can superglue the knots and replace the paracord? Wish there was a better solution.

I love this collar. It is very light weight yet it is strong and well made. I only use the collar to hold my dogs tags and to be able to be able to grab and hold her if need be. I use a loop leash to walk her. Collar lays nicely in her longer neck hair.
