    Nice starter toys
    Color: Pink, Color: Pink
    Decent rubber toys. You get plenty and each one has a slightly different texture / hardness. Our 12 week old yorkie pup especially likes the "bean" and the ring. My issue though is that she is already starting to break the toys and I worry that she might ingest the pieces that come off. Therfore I recommend having an eye on your pup when they are playing. The bean chewie does a good job at cleaning your dogs teeth. The toys are also easy to wash. Overall not bad.

    Choking Hazard
    Color: Blue, Color: Blue
    This item is not suitable for puppies. When chewed on pieces of plastic fall off the toys and can create a choking hazard for small dogs/puppies. I had to throw all of the pieces in this set in the trash.
