Versatile Toy
Color: Blue
My dog loved this toy. The material is like any other plastic dog toy, not super durable if you have a tough chewer. Thankfully my dog has only ripped the top part of it, which I think is because it is textured. Before he ripped it I put treats in that upper portion and it kept him entertained for a couple minutes. The little ball inside also makes it more appealing for pets because it moves around. Overall, a pretty versatile toy!

Durable toy
My dog loves this toy. The rubber is not too hard so she can squeak it well and the ball inside makes her go crazy trying to get it out. Good idea.

A shame
Color: Blue, Color: Blue
This product was disappointing, giving 2 stars because it does seem to be a fun toy for dogs; however, within just a day of me giving this to my two 20 pound dogs, they ripped up the top, pulling off shreds of plastic. Luckily this was under supervision so neither of them ate any of the pieces but I could see this easily being a hazard for dogs, especially smaller ones. Whether choking or ingesting, this could be extremely dangerous. Not very good quality.
