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.

Perfect for small dogs!
Color: Spider
These are so cute. My 10 pound Havanese absolutely loves these. They are the perfect size for her. I couldn’t put them away with the Halloween decor because she carries them everywhere. She has one in the bed, one in the car and one for around the house. Very durable and fun for her.
