Great product, Great price
Style: Mix, Style: Mix
I was a bit skeptical of this toy for the price especially since there were two of them. It is however it is a fantastic product, great quality and it won't deform. Perfect for medium-large dogs may be a bit too big for small dogs but if they are active then it should be fine. It makes a crinkly sound and has a small squeaker so if you want your dog to play and not make a lot of noise this is a good toy. It is soft and good for dogs to chew on so there is no risk of damaging teeth. It is easy to clean. Lastly what you see in picture is what your going to get it looks fantastic. All and all of you want a humorous to that isn't just a novelty I would highly suggest this.

Our pup loves a cold one!
Style: Mix
Our pup (dog) loves these! Something about the crinkle noise. We had gotten a four pack at Christmas and we’re needing to replace them because they had just gotten so dirty and gross even after washing them. We were so happy to find them and will definitely be purchasing some more in the near future! It’s good quality especially if it lasted 6 months for our dog! The appearance is just like the picture! And they are soft! They are perfect for our 50 pound Shepard mix dog.

May not last but worth the purchase

Furbaby loves them. I’m not sure how long they’ll last, but we will see. Giving 4 stars because the puplight squeaker doesn’t work.

Got these for my dad’s puppy. I can’t wait to see his face when he opens it on Christmas. They feel durable and have a nice noise when the pup plays with it. Absolutely love them! Extremely funny and fun for the pup:)
