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!

Terrible quality
Color: Tennis Ball (Green), Size: 1 Count (Pack of 1)
After purchasing several of these balls, I felt I needed to write a review so that the amount of sales doesn’t make it appear as though this is a quality product!!
My dogs absolutely love these balls, which is the only reason I keep ordering them. But, the grunting effect is “killed” quickly and easily and the seam that connects the “top” easily pulls apart. The balls end up ripped in two halves in less than a week. Sometimes less than three days. (We leave them outside so they play with them only when out there).
They’re just far too easy to “disassemble” and tear apart. But, it’s fun watching the dogs’ joy in the first few seconds of getting a new one.

KONG; consistently sturdy!
Color: bone, Size: 1 Count (Pack of 1)
This toy is small enough for my 11 pound puppy and he loves it. It's also sturdy enough (as KONG products always are) to withstand his terrier jaws and ability to destroy most toys in under 5 minutes. Keeps him busy for hours.
