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.

Adorable little toy
This toy is ADORABLE, however be aware it is very small. A larger dog could choke on this. My little 10lb dog loves it. The only downfall is there is no squeaker. I would buy again.

Miniscule waste of money
This is half the size of a tennis ball. I am returning it because it is a waste of money to buy. Might work for a Chihuahua, but I have a Dutch shepherd. No way will this be a appropriate for a dog. It also lacks a squeaky sound. Cannot recommend.

Great quality and long lasting
Size: 5.5 Ounce (Pack of 1)
My dog loves these, and I feel good giving them to her. They last a very long time. They don't have any odor whatsoever. She chews them aggressively, but they don't leave as much slobber or goo as some other chewables. They are pricey, but if you just bring them out for a special treat, they will last longer. I bring it out when we're having dinner, and I don't want her to bother us! When she gets it down to a nub, I stuff it inside one of her puzzle toys and she is still very interested in it because I guess to her it must really smell great even though I can't smell anything at all. So she will try to dig it out of the puzzle toy and spend lots of time doing that, so I feel like that gives some extra value.
