Too flimsy but a crowd pleaser
Color: Spider
My dogs absolutely loved them so I gave it 4 stars but it probably only deserves 3 stars due to how easily these can be destroyed. I have small dogs and they destroyed them very quickly.

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!
