not indestructible
Color: 1PC
My dog ate through it in 4 days. The bear is not indestructible. It died a very undignified death. I am convinced that my dog was a goat in a past life. He eats everything that is not nailed down.

Not worth the money
Color: 1PC, Color: 1PC
DO NOY BUY!! It lasted not even 3 minutes with my 6 year old rottie. She bit right through the nose and pulled out the stuffing. Don't waste your money!! I would give it zero stars if I could!

Not good for an aggressive chewer
Color: 1PC
This toy is not indestructible. My little Aussie had one ear off and its neck cut in less then 6 hours and by the next day he had the foot chewed off. It is cute and he loved it, but it is stuffed and not really safe for an aggressive chewer.

It is not a good product for a dog. I didn’t even last five minutes.

I received this package and I just gave it to my dog. Doesn’t last five minutes. It’s already tore up.

A real review.
Color: 2PC, Color: 2PC
When I saw the Unbreakable Teddy Extreme Bear 2.0, I thought, Finally! A toy that might survive my 9-month-old Rottweiler puppy, Pepper. She’s an aggressive chewer with a love for stuffies—she adores them, right up until she disembowels them and feasts on their cotton insides like a tiny, unhinged zombie. The toy’s name, "Unbreakabear," sounded promising. Durable? Stuffie-like? For large breeds? Sign me up!
Fifteen minutes later, it looked like a crime scene from a horror movie.
The Good:
Pepper was IN LOVE with this toy... for about 10 minutes.
The double pack is nice in theory—you know, so you have a backup when the first one inevitably doesn’t live up to its "unbreakable" promise.
The Bad:
False Advertising: This toy is marketed as "extremely durable for aggressive chewers." But let me tell you: Pepper’s chewing isn’t aggressive—it’s surgical. She shredded the bear’s ears, ripped off the tail, and then went straight for the brain like she was auditioning for Zombie Dogs Gone Wild. It didn’t even put up a fight.
Durability (or Lack Thereof): Calling this toy "extreme" is like calling a paper towel roll a chew toy. One good shake, and the seams basically exploded in surrender.
Safety Concerns: Once Pepper exposed the stuffing (and the metaphorical "brains"), it was a race to see if I could stop her from swallowing it. Stuffing everywhere. The floor looked like someone had murdered a carnival bear.
The Ugly:
Walking into the room after Pepper was done was like stumbling upon the aftermath of a teddy bear massacre. The "Unbreakabear" lay limp on the floor, its ears and tail missing, stuffing spewed around like it was the victim of a bear-sized horror flick. Pepper, triumphant, sat there with bits of fluff clinging to her mouth, looking like a deranged extra from The Walking Dead.
Final Thoughts:
If your dog is a light chewer who likes to gently cuddle their toys, this might be fine. But if your dog sees toys as a challenge, run. Stick to hard rubber toys, Kongs, or something without a vulnerable, squishy middle.
As for the warranty? Sure, I could try to get a replacement, but what’s the point? Pepper will just go full zombie surgeon again.
Would I recommend this toy? Only if you’re filming a sequel to Teddy Bear Massacre. For aggressive chewers, this is nothing but fluff and disappointment.
Pepper’s Review: 5/5 stars for taste. 0/5 stars for durability.
