Remains a favorite
Color: Orange
This toy was perfect for my pup who's a big biter and most toys will last about 2-3 days. The material on this toy is very durable and remains the favorite with the crinkling sound.

Not for tough chewers
Color: Blue
Cute toy, good concept but definitely not for super chewer. Got it at such a price that I let him destroy it because he was having so much fun. You only have one birthday a year after all.

fun toy
Color: Orange
Very cute toy .My dog loves it. He is hard on toys and loves playing pully. So far it is holding up really well. It is a good size for medium to large dogs. I think if you have a small breed it may be to large. The color is a vivid orange and white. I really think your dog will love it.
