Puppy Loves this toy
Color: Tie Dye Blue
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.

The pooch is on Cloud No 9
Color: Blue
Lucky loves everything about this (blue) octopus. It has squeakers in all the right places and the crinkle sound adds to his fun. He’s almost 70lbs and extremely strong, and can be an aggressive player and chewer. So far, it has held up extremely well for the tug-of-war games and crazy shaking play. It’s well worth the money. I also want to mention that this toy is true to size. I have too often ordered dog toys that turned out to be much smaller than advertised.

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!
