大型环（适合60-100磅犬只） — Goughnuts

My 80-pound lab mix has destroyed every other toy we've tried, but this green ring has lasted over a month and still holds its shape. The rubber is thick but gives just enough to be satisfying for him to gnaw on. I love that the red safety liner will tell me when it's finally time to replace it.

My 90-pounder goes through toys like they're made of paper, but this green ring is holding up after three weeks of constant gnawing. The red safety indicator inside is a smart touch—gives me a clear signal when it's time to swap in a new one.

My 75-pound lab has destroyed every "indestructible" toy we've tried, but this green ring has survived three weeks of daily tug-of-war and still feels solid. The rubber is thick and springy, and the red indicator inside gives me peace of mind that I'll know when it's time to retire it.
