Not long lasting for a chewer!
Size: Medium
These are massive! I have a golden retriever puppy and she chewed through the yellow ring very quickly. They keys are much more durable.

Great for puppies- have purchased several times
Size: X-Small
I have purchased this toy for a couple of the puppies in my life and they always love it. It’s not noisy, it’s made for puppies to chew (so it’s not too hard), and it’s fun for them to carry around with the different keys and key ring. A little pricey, but it always lasts a very long time- longer than they are a puppy!

Safe and Entertaining Chew Toy
Size: Medium
My dog absolutely loves this toy! She gets hours of chewing time out of it, and I feel so much better knowing the keys are made of a material that’s gentle on her teeth. Unlike harder toys that can chip teeth, this one is durable yet safe, and it keeps her happily entertained. Definitely a great choice for any dog that loves to chew.
