Works great for my goldendoodle. It’s held up well to two dogs and lots of playing. It’s nice and large and has held up outdoors in Michigan winters

Sturdy and holding up so far!
Size: Small 15", Style: 3 Knot, Pattern Name: Dog
This is a quality pull toy that my Yorkie ("Finnegan") loves. It is holding together well as my dog can be a maniac at times. Moderate chewing has not hurt this toy. I do not buy toys with squeakers in them as they worry me. Finn entertains himself and then brings toy to me for a tug of war. I recommend this item. Good bang for the buck!

EXCELLENT QUALITY
Size: Medium 20", Style: 3 Knot, Pattern Name: Dog
I have a German Shepherd/Pointer mix who is 10 months old. He has been in the throes of teething and destructive exploration. He's chewed up clothing and shoes. He chewed a hole in our couch and one in our brand new mattress (He was never left home alone until this point but as my mother came to visit and my boyfriend was back at work, I had no choice but to trust him alone for about an hour a day for 3 or 4 days... he clearly didn't earn that trust). He loves ropes because he can gnaw them, whip them around, and play tug of war or fetch with them at any given time. We love ropes because they keep him occupied and relieve his desire to chew things. Unfortunately, he was destroying rope after rope after rope. Some ropes were worrisome because they would quickly start fraying and falling apart. We would have to help remove strings he has swallowed from his behind while he was out doing his business... My boyfriend's mother picked up a Mammoth TireBiter tire and rope toy for him but it was much too small. Still, he loved it and it stood up very well to his chompers despite being way too small/weak for him. Looking for a larger version of the Mammoth TireBiters, I stumbled across this rope toy and gave it a shot. Let me tell you, I don't think I will ever buy rope toys from any other brand! We have had this rope for over a month and it is still going strong. It does show some small signs of wear and tear but you would swear we bought it last week. It is very strong and durable. It has held up through many long gnawing sessions. It has been put through countless hours of fetch and tug of war with no signs of giving out any time soon. I am so in love with this rope and so is my pup!
