Lasted 2 minutes
Color: Grey, Color: Grey
Gave it a 2 star bc it was cute and on time.
I have a GSD- a mildly aggressive chewer. This toy literally lasted 2 minutes and there was stuffing coming out so I had to take it away. Wish I would have read the reviews before I purchased.

Only Made It Two Weeks
Color: Grey, Color: Grey
This toy easily became my Fig's favorite toy. The squeaker wasn't as annoying as it is in many other dog plushies. However, that's where the positives end.
After the first week, there was a hole in the stitching on its neck. I sewed it up, but it obviously did not last. The squeaker went silent after a few more days. I bought it on March 28th, and it is now April 12th. It's just a rag, now.
RIP little honey badger. You did well in your short life time.

Not 100% indestructible, but cute and worth the money
Color: Grey, Color: Grey
My dog absolutely love this little toy although when I looked up indestructible dog toys, this is one of the first things came up. I have to say it is not indestructible. I have not found one single dog ball or chew baby that is indestructible. My dog has found every which way to destroy them. It is now four days later and it’s still almost intact, but she has placed a hole in it. It does come with a squeaker, although the second day she already pulled it out it’s cute and it’s fun. Your cat could technically play with it if you had a cat and they wanted one quality wise, I would say it’s definitely close to indestructible, but it’s not completely indestructible and the colors were so fun.

It's not indestructible.
Color: Blue
Buyers beware, I have a jack russell, and I just got this item ten minutes ago, my dog ripped it up.It is not indestructible, it is a waste of money. My dog is very aggressive with his toys. So back to the drawing board...So I can't return this item because, it's ripped up and they're not gonna give me my money back... So do not buy this toy.

P.O.S.
Color: Grey, Color: Grey
Toy is not as advertised. It is NOT for aggressive chewers. It is NOT indestructible. It is NOT for medium to large dogs. I knew the moment I opened it that it would be demolished by my 24 pound Miniature Blue Heeler. And here we are 5 minutes after giving it to him, picking up pieces of cotton off of the floor. This should be marketed as a kids stuffed animal. In no way shape or form is this a chew toy unless you have an aging toothless two pound Chihuahua. It would have taken longer for my dog to chew up the $10 dollar bill I gave for this. 💩
