    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.

    Cost effective option to find what kind of toys you new small pup will enjoy.
    Color: 12 PACK PUPPY TOYS
    This was a great puppy toy assortment. It is great because it has different types so you can figure out what types of toys your new pup will enjoy. This package is only suitable for small dogs. Also, I do t think they would be good for aggressive cheers. But if you are looking for a cost effective bunch of small new puppy toys this is perfect. There was no smell, the sound of squeaker were average high pitch, soft and moderately durable, design and appearance were generic. Not high quality but a good assortment. Not suitable for long term use IMO.
