I have a 6 month old GSD. She loves this toy. She is a very hard chewer and normally destroys the so called “indestructible” toys i get from the store within a matter of minutes (seriously). But this one is able to stand up to her dinosaur teef. She loves it. Very sturdy. She can chew and chew and has yet to ruin it! I should get a second one as a back up! I recommend this for large dogs or any dogs that love to chew.
