Large dog rope toys, hand knotted from 1 piece of 5/8" dense cotton rope.. This one is 8/10 of a pound, knotted, woven and tightened not to unravel or pull apart. I'm filling a need for BIG, STRONG dogs to have satisfying toys for enthusiastic tug and toss play. No rope toy an survive being left as a chew toy, but these will handle all the rough play you can give them. Machine washable!
