Our dogs love these
Color: Orange & Blue
We have two rough collies that love to play fetch, tug, and ragdoll. We decided to add these to their play toys. Since getting them they have been ignoring their ducks and going straight for the octopus. We just got them so can’t say much about durability yet but they have been playing with them for hours and still look brand new. Love giving our dogs choices so we can ask them for certain animals to fetch. Love the non-stuffing and the crinkle.

Not for Aggressive Chewers
Color: Orange & Blue
My Dog Loves them. He immediately took the squeaker out, and dismantled some of the legs, but he still runs around trying to play tug-of-war and fetch with the dismembered body piece's 😂☺️

Didn't even last an hour!
Color: Orange & Blue, Color: Orange & Blue
I had high hopes for these toys as the description sounded like they might be not easily destructible. Well, I was dissapointed again. Our shih-poo (half shih-tzu/ half minature poodle) had one of the toys apart in an hour. See photo.

Stuffed with Plastic
Color: Orange & Blue
So these are super cute and they have crinkle sounds and a squeaker, but these would not be suitable for chewers. The have plastic stuffing in the legs and my dog almost choked on it...so I just have to tell you that these may be ok for smaller dogs but mine is 30 pounds and he ripped through it and started eating the plastic crinkle stuffing.
