Strong, tightly woven and good, clean cotton. The dog loves it and so do we. Worth every penny.
Great toy! Keeps my dog busy for hours, until she decides she doesn’t want it any more and tears it into a million pieces. Glad it’s made out of the right materials, so I don’t need to worry if she swallows anything!
We really love that this toy is both made of cotton (only) and in the USA. Other ropes are made of "blends" that nobody knows what’s in them. This toy is our retriever’s new favorite, for now ha,ha,ha. It frays though, but we prefer that to “indestructible” toys. It is great to be able to buy toys for our pup that we can trust.
My pup chewed thru it in a couple weeks, so we had to order a new one. We still prefer it to synthetic ones though. It maybe the smell but he loves to sleep with it. Great destructible product!
My border colly loves this toy, it’s her favorite by far. I bought these about a month ago and even though we play a lot, they have frayed just a bit. I bought two, one stays clean inside and the other one outside. I love that it’s made in the USA from US grown cotton only.
Day one we took this rope outside and it ended up stained with dirt and grass. White rope doesn't hold up well outside. Anyway, I was able to wash it and since it's just cotton most of the stains came out. Other than that, my dog likes it.
