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.

Love this and very durable!!
Color: Blue Spider
This spider is HUGE! It's sooooooooo nice! My 3 boys love it! They love chewing on all the legs and it's so big that they can all lay around it and each chew on a leg at the same time! They also play tug of war with it at times! It's stuffed with a cushiony material. It does not bounce. It's lightweight. Has no smell. It's so much fun for my boys! Love it! It has great durability as my one boy who literally destroys all his toys has not broken it and they've had it for 3 months so far! This alone speaks volumes! Highly recommend!

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.
