      Only “tough” toy my Doberman loves!
      Pattern Name: Octopus
      Not indestructible, but last a good long while. Definitely worth the money and lasts longer than any other plush toys we’ve had (which is all my dog will play with). It’s for sure my Dobermans favorite, I’ve ordered probably 10 at this point. He gets the stuffing out after a month or two and we open a new one. He’s picky with toys, either destroys them or ignores them, but he never gets bored with his octopus! 🐙 He sneaks one outside once in a while and the neighbor’s dogs steal it. They love it too and thankfully can’t destroy before I retrieve it.

      Great for a Pitball
      Pattern Name: Octopus
      I have a Pitbull and she absolutely loves this toy. I always wait a while before giving a review. She has had this toy Since the beginning of July and she is still playing with this toy. It does have little holes but it is still going. She loves it. Playing tug of war with her. I also take it and wrap it around her collar and watch her dance around trying to get it out(I don't leave it there long). This a great buy. I also bought and extra one so when this one does finally dies she will have another. The material is strong, The sound is about normal for a squeaky toy.

      Cute, but not tough enough.
      Pattern Name: Octopus
      This toy is cute, my pug loves it, and I like how the legs are strong but the top of the octopuses head isn't tough enough which is worrisome because thats where the squeaker is. It might work out for a smaller dog though.

      Fun Resilient Chew Toy
      Pattern Name: Octopus
      I have a boxer/pit mix and she loves this! I bought it 4 months ago and it’s still going strong so I know it’s quality made and perfect for dogs that like to chew and play tug of war. It has been chew resistant for my girl and she loves the little squeak. I just throw it in the washer when I wash her bed. Great value and a safe toy that’s a good size for a medium to large dog.
