We have two dogs: one elderly english bulldog (who's very gentle on her toys and doesn't destroy anything) and a one year old pit bull terrier mix. We gave the binoculars to our bulldog first, and I was surprised after a couple minutes of light chewing and then promptly falling asleep that she had left teeth marks in it... so was wary about durability from that alone. When our pit bull played with it, chunks started falling off the toy in less than a minute and we had to take it away. This is from less than 5 minutes combined play from both dogs. Our stuffed animals have longer play time than that with our pit bull... so this is bizarre. Not for super chewers at all. Disappointed.
