I have trouble finding toys that my 4 year old chocolate lab won't chew up right away. I was encouraged that this toy was labeled as "durable" and it was supposed to entertain your pooch for "hours". Sadly, my dog was really excited about the toy but she was able to start tearing off chunks of it in just about 15 minutes (at which time I had to take it away from her). So, this toy is definitely not for aggressive chewers.
