Don't buy this product
I saw there were some bad reviews for this toy, but they didn't worry me as our dog is incredibly gentle with toys and hasn't chewed through anything we've ever given her. Stupid mistake.
Within 30 minutes she'd half chewed through the nylon rope, and the rope was fraying and splitting. I wouldn't have been overly worried if it was cotton rope, but as it's nylon this definitely is a choking hazard.
Frankly this toy is dangerous and shouldn't be on sale.
