Cute, but only lasted a day. Not for hard chewers

Sturdy rope
Size: Medium (23.60")
Very sturdy rope. My dog is a heavy chewer and this rope is perfect for her.

This is the one for my dog, (and maybe yours)
Size: Medium (23.60")
Great dog toy! Got the larger size— less accidental hand bites that way. It’s our second one, but the pup is a strong chewer so no disappointments with the product at all. Many breeds would not do what mine did to the rope. I love that it’s natural cotton. The longer version that I ordered comes with 3 knots, including one near each end— great— and one in the middle, which I don’t like or need. It’s a tad difficult to untie the central knot, but it’s possible with a screw driver or awl, and then it’s a perfect toy.

Does not fray.
Size: Medium (23.60")
My 70# poodle loves playing with it. She throws it in the air and catches it and brings it to me and I throw it or I tug with her. It’s very sturdy.

Rope chew
Size: Medium (23.60")
It’s perfect for an over aggressive dog chewer, especially a puppy has worked phenomenally. Well he has not chewed through it, which is amazing. We’ll get it again, but a bigger one as he grows.
