It comes with K&N million mile limited warranty and it will not void vehicle warranty.

Perfect combo of frisbee and rock.
Pattern Name: Tug Frisbee, Size: Large
Looks like a frisbee, flies like a rock. This is definitely not for exercising your dog. It is not a flying frisbee. Not at all.

KONG Tug Toy
This tug toy is decent but not amazing. It’s sturdy enough for light play, but it doesn’t hold up as well as other KONG toys we’ve used. My dog enjoyed it, but the material started to wear faster than expected, and it didn’t feel as durable as the usual KONG quality. It’s fine for occasional tug sessions, but not the best choice for strong pullers or heavy chewers.

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.
