Not For Medium to large dogs!
Color: Navy Blue, Color: Navy Blue
You should know that if you have a medium sized dog this toy is not for you, Although it is listed as indestructible, the toy did not last one day. The ears were torn off before the first day and stuffing was ripped out of it before the second day! However, he really loves the toy but it's not indestructible. All in all though the product should be recommended for small dogs but still I realize that I'll probably be buying another one in the next 3 to 5 days.

Not worth it, not indestructible
Color: Auburn, Color: Auburn
I'm giving no stars, thought this toy would last longer than 10 mins with my dog. Guess not, it says indestructible in the details but as you can tell that's a total lie. Not worth the money at all.
