Perfectly Spooky & Shih Tzu Approved!
Color: Skull With Spiders
Mushu and Cri-Kee are absolutely obsessed with this Fringe Studio burrow toy. It is so hard to find plushies that are the perfect scale for a Shih Tzu, but these spiders are exactly the right size for them to carry around and "hunt." The spiders are super squeaky, which keeps both of them entertained for much longer than their other toys. It is adorable watching them dive into the burrow to find their prizes. This toy is high quality, holds up well to their play, and provides the perfect amount of mental stimulation. If you have small dogs who love a squeaky challenge, I highly recommend this one.

Great size for tiny dogs!
Color: Skull With Spiders, Color: Skull With Spiders
We got this for our grand-dog, a tiny Havanese! It's a great size for her. It was challenging to find things she could carry around with her tiny mouth when she was a puppy and we liked the added bonus of her pulling them out of the skull. Another activity in her day.... It was the perfect seasonal item to add to the toy box. It's her favorite thing to carry around. The squeakers are still going strong. It got a little crusty after she played with them for a while, but they washed great! Still holding up! Would recommend.

My little dog's favorite toy
Color: Skull With Spiders
These spiders are small and not for big dogs. But my little one loves them so much and it is hard to find good durable toys small enough for her. I love these spiders so much I wish I could buy just the spiders. the ones they sell alone are too big for her. If some one from the company could help a sister out on how to buy the spiders without the skull I would be for ever grateful.
