Excellent dog toys! They arrived quickly, look exactly like the pictures, and my dog was excited immediately. Good quality stitching and no weird smell. Perfect for chewing, tossing, and playing fetch indoors. Would buy again!

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.
