Aggressive chewer (terrier) approved!
Color: Blue Octopus
I would give five stars except for one small area. The back seam was too easy to access to get the squeaker out (literally under half an hour of him playing). ***BUT*** the legs are SO strong and can be used for tug of war and they are crinkly and he loves it. Highly recommend!

Not bad, wish it was more durable
Color: Blue Octopus
My Australian Shepard loved this toy! However, it is NOT VERY DURABLE as advertised. He ripped off a leg within 20 minutes of getting the toy.

GREAT FOR MY LITTLE ADOPTED DOG!
Color: 6 pack
These little soft dog toys are wonderful for small to medium sized dogs. I recently rescued a dog who had never seen a toy, nor did she know how to play with them and these are perfect. She is a 13 pound half Chihuahua/terrier mix, and she loves to play with these little toys. They’re cute to me and she likes them so that makes me happy.
