Love this Collar!

This is a great collar and the size worked well with our little small adopted mix. The collar is well made, the materials are strong, and most of all the collar is easy to get on and off. Lastly, we like that the collar is very minimal and doesn't bother our little guy when wearing the collar all day.

Love This Collar!

I didn’t want a tight or heavy collar for either of my dogs. They both wear harnesses when out on walks so I wanted a lightweight collar for their tags. The Knot a Collars are perfect, adjustable and comfortable. And we get lots of compliments on how nice they are!

Easy collar

Love this collar! Easy to take on/off, dries quickly when wet and doesn't dig into the fur and leave marks like other collars.

Knot a collars

I love the look of the collar, but when you attach a leash and your dog pulls, the collar does loosen. It is frustrating, but I like the look so much that I am dealing with it.

Knot a collar

My little corgi Doesn’t like harness at all. So I kinda gave up on that because he wasn’t very cooperative until someone told me about this brand and after I saw the good reviews I decided to buy one And honestly that’s the only harness I know can fit corgi pups really well I can’t wait to Buy a second one
