    Kong didn't survive this guy.
    He had it for an hour.. We played tug for around 10 minutes then he took it off and chewed it up.. I thought Kongs were tougher to chew up.. very dissapointed.

    One of the best dog toys we've found
    This is one of my little girl's favorite toys. She's an aggressive chewer so at first we followed the manufacturers instructions not to let her use as a chew toy. It was purchased in January 2025, but it's holding up just fine. She likes to turn it into a pretzel for some reason, but hey it keeps her entertained! Highly recommend.

    Good for play but don’t leave out to be chewed on
    With two labs we need durable toys. This can stand up to the teeth when pulling but we can’t leave it laying around or it has chunks chewed out of it. And it’s not the toys fault that my girls can’t figure out how to each take a side, so it’s a human vs dog pull toy.

    Toy is strong enough for a Rottweiler.
    This is one of my dog’s favorite toys. He is a Rottweiler so I have to get him strong, sturdy toys. He hasn’t broken it yet!
