The Ruffwear Knot-a-Collar is a strong comfortable dog collar.  Climbing rope inspired, this collar is made from 7m rolled rope which settles into the fur and reduces matting.   It is a clean, sporty, yet elegant 'every-day collar', which has curved all-metal hardware to keep your dog secure.   There is reflective strands in the rope for better low-light visibility and the collar is fully adjustable.

Why not match up the Knot-a-Collar with either a matching Knot-a-Leash or a Knot-a-Long dog lead?

The new colours also pair up nicely with the Front Range Harness

Knot-a-Collar - Climbing Inspired Dog Collar

Love it!

Having whippets I can’t use this as a walking collar (can only use slip or martingale collars) though I couldn’t resist rounding out my matching set with this beautiful piece as a tag holder. Incredibly well made, quality fittings & no jingle tag holder, perfect! Oh and absolutely gorgeous too.

Thick Mane? This works!

I was looking for 2 major things, 1 was a narrow soft collar that will comfortably sit within my Cattle Cross’ thick mane and 2 was metal parts that won’t discolor her white coat. This collar ticked all the boxes. She doesn’t scratch at it like her flat collars and it looks cool too.

The collar is lovely. My only complaint is if you hold directly onto it, it slips making it bigger. I do love it anyway my 34kg yellow Labrador wears a large and he looks very handsome.
