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.

Best small puppy toys
Color: Purple
This is one of the best puppy toy for heavy chewers. I have a 3lb chihuahua who chews as much as my Labs would. The pieces don’t fall apart in little bits and keep her busy for a little while. One of the best parts of the toy was the braided cloth attached to it. The cloth is soft and doesn’t shred like a rope toy so no swallowing bits of rope and no getting nails stuck in rope. I highly recommend these toys for you little chewers! PS Would love to see if they make any other toys. Their website is very tiny and has no contact info.

Cute but potentially a choking problem
Color: Pink
My 5 month old miniature poodle actually bit off the little knobs on a couple of these toys. Needless to say I took them all away from her. They are cute toys but not really safe

Goldilocks of dog toys!
We recently rescued a small/medium bulldog breed (35lbs) and she *loves* toys. Problem was that our other dog's (75lbs) toys were too big. They literally were the size of her. We found that our new baby pooch was constantly raiding our cat's bed with the cat toys. They were more her size and she knew it. I bought her some cat toys (mostly mice with catnip inside and a yarn tail). She *loved* them, but they were too small. She would choke on them and I would literally have to pull them out of her throat by the mouse tail. Scared us too much so we gave (all 20) away to a friend. I scoured Amazon and found these whimsical toys and they are *JUST RIGHT*! Perfect size, have held up several days of chewing and gnawing, squeak pretty well, and my big dog also loves them! These deserve the 4.9 (5.0 but can't please everyone) rating that lead me to purchase them in the first place. Buy with confidence for your medium size (or any size really) fur baby!

Super Cute!!
These adorable toys are incredibly cute! My 9-week-old puppy absolutely loves them. There are so many different options that I can easily rotate them to keep him entertained and prevent boredom. So far, they have held up well against his teething, and I've even needed to wash a few of them in my washing machine due to potty training. They are perfect for small dogs and puppies and offer great value for the price.
