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.
