Perfect Puppy Starter Toy Set
Color: 9 Pack (No-stuffed Fox), Color: 9 Pack (No-stuffed Fox)
This toy pack is such a great value for puppies. My puppy stayed entertained for hours and loved having different textures to chew and play with. The toys feel soft but still durable enough for everyday use. A few of the smaller toys are better for light chewing, but overall it’s a fun variety pack for keeping a puppy happy and active.

Very small toys! But they are fun!
Color: 9 Pack (No-stuffed Fox), Color: 9 Pack (No-stuffed Fox)
All the toys in this pack are very small. I almost sent it back because I was worried they’d be too small for our new puppy. I’m glad we didn’t though because she loves all the toys. Her favorite is the fox because it makes the crunchy plastic sound. She will outgrow the toys but for now this was perfect for her.

Great Toy Bundle
Color: 9 Pack (No-stuffed Fox)
My puppy loves these so much that I purchased a second set! The toys keep him engaged, are very cute and soft, and so far have withstood the wrath of a slightly psychotic furchild! Highly recommend!

My puppy loves this set
Color: 9 Pack (No-stuffed Fox)
It’s been 15 years since I had a puppy so after I adopted a 9 week old puppy, then I realized I had no toys for her! I wanted a variety at a reasonable price. And fast too! This arrived the next day and she immediately started playing with everything. I think her favorite is the fox but she loves them all. The first time she heard the avocado squeak was priceless. She also loves the rope toys but they shred so I limit her time alone with them.
These probably won’t last a long time but they were a good price for a lot of variety of items. She is happy so I’m happy. Thanks
