My girl blood-eagled this poor thing within minutes but she had one heck of a time doing it! If you're looking for durable, this probably isn't for you. If, however, you're looking for some quality entertainment for you and your dog, look no further. A little reconstruction and ol' Larry was ready for round two of being eviscerated. Solid toy, real cute.

Not a terrible toy

Color: Blue Cow

Not a terrible product, but for a super sure it doesn’t last very long. It’s cute, but this is meant for definitely a small two small medium dog.
