This is not even chew resistant!!
Color: Brown
If there was an option for ZERO stars that would be this. Within 5 minutes my little 11 pound Havanese had all the ears off, then out came the stuffing. He had the little dog, and a green duck. I had to take the duck away to sew it….then he still had studding everywhere…and that was the little dog. Throwing stuffing and pieces away….I should have put these right back in the bags they came in. In no way ate these even chew “resistant “!!!! Probably just look good onna shelf.👎👎

Not quite "indestructible"
Color: Green+Brown
These toys are so cute! But, they are NOT for aggressive chewers! 15 minutes and they were ruined. But for kinder chewers...they are adorable.

Easily Destructed
Color: Green+Orange
My dog destroyed it within a couple of days. The “rope” turned into strings which is dangerous if eaten
