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.

Colorful, Durable, and Totally Adorable! Perfect for Halloween

Color: Bats, Color: Bats

I absolutely love these bats! I’ve bought them multiple times and still adore them… they add such a fun, whimsical touch to my Halloween displays. The colorful wings give them a unique charm you just don’t get with typical black bat props. The quality is impressive too: even after a couple of rainy outdoor seasons, my first two sets are still holding up great. And yes… I know they’re technically dog toys, but my pups already have plenty of playthings… I’m pretty sure they don’t mind!
