Great for teething puppy
Color: Pacifier, Size: Small
I was trying to find something very sturdy for our puppy that she could not bite pieces off of and this toy has been great. She loves it and it has held up very nicely. They are not soft so it is great for our teething pup. They are also the perfect size if you have a bigger pup like we do. She is a 4 month old pit mix. I would say they would be too big for a small breed puppy

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!
