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.🥰

Fun while they lasted
Color: Green
I ordered two. One for each pup. Both my puppies loved this toy. The first one lasted less than a day with my pup who loves to do the death shake on everything. The second lasted two days with the other as she chews in the same spot. They loved the crinkle noise. However, I'm taking one star away due to not lasting long. Everything else was fine and they enjoyed them while they lasted. Note that most toys do not last long with my pups.

My puppy is a 7wk old Great Pyrenees & Lab mix. He loves this toy! Fun for tug of war and for cuddles. Definitely worth the money. It is durable enough for razor puppy teeth.
