Only good for small dogs
I didn’t pay attention to the size and it’s really little. Thankfully, my dog is small.

Please read reviews/description before buying
I specifically had to read reviews/description before purchasing (Both small/large versions) . I had ordered the large for a shih tzu and its still kind of small, but she does enjoy it

Tiny toy!
This thing is tiny!! A bigger dog could swallow it. The description states there is a squeaker in it, no there is not. What a ripoff!

Not suitable for large dogs
The pictures misrepresent how tiny the crab is. Choking hazard for large dogs. Very disappointed. Waste of money, shipping and time.
