Octopus dog toy
Color: Blue
My chihuahua loved it but didn’t last very long. Not very durable and was very small. He was able to get the plastic material out fairly quickly.

Tasha's favorite toy
Color: Blue
A little smaller than expected, but my puppy loves it! We've only had it for a few days, but it seems like it will hold up well.

Not for Destructive Dogs
Color: Blue
It might be okay for a little dog, but my heeler had it dismantled in short order and I threw it away. Cute toy, but not for a destructive dog.

So cute!
Good size toy, but my 1yr old Jack Russell is NB match for it. It’s good quality and I’m sure it would last longer with a less aggressive chewer.
