Cute toy that definitely entertains the pups.
These are adorable toys. They make a bit more noise than I expected as they have the crackly ‘stuff’ in the legs. My mastiff made it a whole day without destroying it. This is the first toy that’s survived him for more than 10 minutes, so that’s an endorsement even if it sounds bad. They are a great price for the size. If I were to say I have a wish for them, it’s that the material that makes up their belly was more durable.

Durability Not So Good
The size is great and having squeakers in all tentacles is super for the puppy but had to sew a seam withing one week of having it. Hoping the rest stays together.

Long lasting and fun
This toy has lasted longer than other octopus toys I've bought in the past. Even if a leg or two is ripped off, it still holds on.
