When impact testing the Ruff Tough Kennel, we dropped it from a height of 12 feet with no noticeable damage, so we kept trying. After four drops the kennel showed only scratches and stains from the concrete and grass. No splits or cracks were evident. The Ruff Tough Kennel was fired at with a full choke charge of number 6's from about 15 paces. To our surprise only a handful of pellets penetrated. The rest buried in the material. We were satisfied that it would provide maximum protection from a few errant pellets in a hunting situation. We've received testimonials that our kennels have also been involved in actual car accidents and are happy to report that dog and kennel have survived each and every time.
