I, too, have a large dog. Every toy I would buy for him, he would tear it up and/or pull the stuffing out of it in about 5 minutes. Then I found the kong toy and decided to purchase it. It keeps my dog happy for hours. I like how you can put a treat inside of it and it keeps him busy trying to get to the treat. It definetly holds up to his powerful teeth and I would recommend this to anyone who has a dog!
