This is a reliable option for a heavy chewer, especially for a large breed with a strong bite. The material feels tough and well-made, and it stands up well to consistent chewing without immediately breaking down like softer toys tend to do. It also gives a bit of dental benefit by helping reduce plaque and tartar buildup during play, which is a nice bonus since brushing isn’t always realistic. The textured surface keeps it interesting enough to hold attention for a while, and it doesn’t splinter or create a mess. Overall, it’s a solid, durable chew toy that works well for strong chewers who tend to destroy most standard toys quickly.

Ergonomic good, material so, so

Nice ergonomic, but the plastic come off and dog chew it. I had rather have a stronger material adequate for bigger dogs.

Love it, nice for tough chewers, split in half during play

Size: X-Large, Color: Textured Ring, Size: X-Large, Color: Textured Ring

LOVE THIS PRODUCT, would’ve gotten 5 stars but i threw it for my dog and it split in half on contact with the floor. It had lasted us well over 5 months, it’s not his favorite toy but he’ll pick it sometimes, i wouldn’t say it’s unsafe in half just don’t give the smaller parts!
