My dogs LOVE these toys!
Size: Small, Color: Assorted Color
These toys squeak loudly and my dogs all love them! My small dogs can eventually get the squeaker out but still carry them around and want us to throw them. They are something I keep on hand (with a supply of new ones available) to entertain them! They are not expensive and will always be their favorites.

Great Buy!!
Size: Small, Color: Assorted Color
My baby loves these. He gets one a week and has the best time playing fetch. One of the squickies quit working but for the price it’s a good deal. He’s a little spoiled!!

Still going strong
Size: Small, Color: Assorted Color
My dogs chew apart EVERYTHING, but all six of these are still in great shape. They prefer and fight over the purple one though for unknown reasons. 🤣

Loud
Size: Small, Color: Assorted Color
I have mixed feelings about this product. I bought this because my puppy kept breaking the squeaker in his squeaker toys. I wanted something where is the squeaker was more durable. This was definitely more durable, it was also 10 times louder than the squeaker in his squeaker toys. He would squeak it all day and night and I could barely hear anything over it. If you asked my puppy to give the review, I’m sure he’d give it five stars and a glowing review, but for me, it was too loud of a squeaker.
