Pup loves it. Hasn't torn it up yet. Carries it around in her mouth, chews on it, plays tug of war with it, chases it. I have a Siberian husky terrier mix. She destroys every toy she has, eats the fabric and stuffing, finds seams and rips it out. Glad I found something that's perfect for her size and not so easy to rip to shreds
