Good Dog Toy
Size: 7" XL-Large
My dog loves this. It is rugged and durable. Because of the shape it bounces in random directions. Great fun.

Great toy
Size: 7" XL-Large, Size: 7" XL-Large
My two dogs love to play with this. I bought the biggest size, I have 60lb boxer and 100lb malamute and it has been durable for them to play with. You can also stuff it with treats. If you bring it in the house make sure to rinse it off because it traps dirt in it.

Indestructible!
Size: 7" XL-Large
I’ve bought his for my 6 month old pup as he’s teething bad! So far it’s been the best chew toy ever! I love that I’m able to put treats inside it so he can play with it longer. Love the cute pineapple design! Almost had it for a week and it’s holding up so well! Well worth the price!
