Great product!

The collar is awesome. Very durable and not as bulky as traditional collars. Great quality work and you can tell it will last.

I love ruffwear, but not impressed by this product

I love ruffwear, the quality, the styling, the craftsmanship. This collar howvwer does not work for my dogs. 1. The collar will loosen over time. My dogs pull on it or if tethered will stretch it. I have to constantly adjust to make sure they can’t slip out. 2. It leaves a collar line along the neck. Even though I have short coated dogs (amstaffs) the collar leaves an indentation where it sits on the neck. 3. It is cumbersome to take on and off, not exactly use friends and a hassle to keep sliding to make sure it goes over their head and off. 4 it’s a weird fit in order to prevent dogs slipping out. It has to be for super tight which seems very unnatural in appearance and feel. Otherwise, if it’s fit more comfortably, the dogs can easily back out. Not practical for those short ***** trips and walks to the car where putting in a harness is a hassle. It’s a shame - it looks nice, I love the reflective weaving, and the leash attachment is a pleasant style. However definitely not a good match for my guys. We will keep supporting ruffwear but will definitely stick to the leashes, harnesses, and packs for future purposes. These really are just ornamental at best. Back to our old collars we go!
