Durable Chew-Resistant Hollow Dog Toy Tennis Ball - Eco-Friendly Rubber Puzzle Ball for Biting, Scratching & Play - Perfect for Fetch, Training & Interactive Pet Games

I bought this because my friend had something similar and my puppy loved. It kept her entertained for hours, so naturally I hopped on Amazon to find one. This one showed another ball inside the larger one but when it arrived (it took quite awhile to arrive) it was smushed, did not have another ball inside of it, and when I found a ball to fit inside it my dog had it ripped open in about 5 minutes. She wasn't even being rough with it necessarily she simply bit it and it ripped. I waited for forever to get this and it lasted 5 minutes. Pretty big disappointment.Agree with reviews about not for aggressive chewers. My bad for not reading first but it literally lasted about 10 minutes and then went straight into the trash in pieces.HORRIBLE FOR MY DOG TO SHRED THIS SO FAST MAKING IT EASY TO ACCIDENTIALLY EAT.VERY TOXIC SMELLING RUBBEROur 4 yr. old beagle chewed it into pieces in less than a half hour. We worry that she may have eaten some!.
