Best toy for a puppy who loves tug-o-war
My puppy (lab/shepherd) went nuts for this toy. She loves to play tug-o-war. This is so durable and the grip handles on the end totally help you out. She loves to bit in the middle and will whip it at you to get you to engage with her. The size is perfect for her and the KONG material must feel good for her.

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.
