Love this for our dog
Color: 5 in 1, Size: Small
These are wonderful. They're made well and are the perfect size for small and medium dogs. My yorkie loves them and they're a fun toy to fetch. We love the cannoli and eclair the best since we make those desserts in real life. Packaged well and shipped fast.

A Nice Treat for Doogies!
Color: Cannoli, Size: Large
This is a super adorable doggie toy. I bought the cannoli for my son's beagle. There are no "legs or arms or noses" to bite off and swallow - just a cute little cuddly roll with embroidered features.
