Horrible Quality
Size: One Size, Color: Tennessee Volunteers
Yikes... I wish I had scrolled down to the reviews before buying! While adorable, this has to be one of the most poorly-constructed toys I've ever purchased. My puppy, who is not an aggressive chewer by any stretch of the imagination, had this thing full of holes within 10 minutes and completely destroyed in 20. Very disappointing. I'm glad I got pics right away. Save your $$$!!!
