My Poodle loves this !
Squeaker is fun and sturdy ! My 15 lb Poodle loves it. (His favorite toy) The toys material held up about two weeks before the white stuffing started coming out. I would pay a couple dollars more for a better cover. I have purchased several ... they all last about the same .

Large, excellent toy with many squeakers!
Color: Blue, Color: Blue
This toy is excellent! I’m super happy with this purchase. My dog loves squeakers and there are so many in this toy, plus stuffing for her to rip out, and crinkle paper to take the sensory experience up another notch! It’s also more durable than many other plush-type dog toys, and is larger than expected which is a plus in my book. For size reference, both dogs are around 40lbs. I will be buying another as soon as this one is demolished!

Huge and fun. Good for two dogs to play with together.
Color: Yellow
This dog toy is great! And it's HUGE. Each tentacle crinkles, and the dogs love to play tug-of-war with it. It seems to be holding up well, too. It seemed a bit pricy for a dog toy, but it turns out it was worth it.

My dogs new favorite toy!
Color: Blue
His new favorite toy! My dog absolutely loves it!!! It’s much bigger than I thought it would be so my dog has to be careful when he’s running with it because he will trip on the legs of the octopus. The best part is there is a little squeaker in the bottom of each leg! Bonus!!! If your dog chews up stuffed animals, this will be no different. It is a stuffed animal. My baby just likes to carry it around and squeak it a 1000 times a day. Don’t mind my crazy voice in the video. That’s the voice I use when he’s excited about a toy. He greets me every day with his octopus.🥰
