Don’t waste your money on this one!

Not durable. Grunter squeaker came out of the ball within an hour of supervised fetch.

Great for the price
Color: Football, Size: One-Size
The reason that I am giving this purchase 3 stars instead of 5, isn't because of the product being faulty. The fault is my own. I didn't think this was a squeaky toy. I thought it was solid. I took it out of its package and gave it to my dog. And when he chomped down on it and it squeaked. He dropped it, barked at it and won't touch it. My dog hates squeaky toys. But it's tough but soft and chewy. The price is nice, the size is perfect for a big dog and the playability is great. Just not for a dog who doesn't like squeaky toys.

This is Some Bunny!!
Color: Bunny (Red), Size: One-Size, Color: Bunny (Red), Size: One-Size
We have dubbed this THE BUNNY. Our fur baby doesn’t go anywhere without his support Bunny and loves it more than his cat sister. Bowie is a big boy and an aggressive chewer yet Bunny has stood up to him. Bunny can never go away!
