not at all indestructible. i have an average chewer dog at best, the guts were all over the floor in less than a minute and the squeaky part was out in less than four. felt like an insanely misleading advertisement. "for aggressive chewers, indestructible." massive waste of money. def don't recommend. Cheap quality, I think a lap dog would have ripped it apart in no time at all as well.

Good chew tolerance and the pup loves it

Color: Yellow Lion

Our dog (20 lb Lassapoo) has had the lion toy since Christmas morning; so far so good. She loves it. Would suggest one of the alternative variants instead of the lion. The long mane hairs are easily pulled off and could be swallowed.
