Dog box pads have lots of benefits to them. The pads are made out of a high denisty foam which gives your dog a more comfortable ride and is easy on their joints. Pads are great for having them in your house for your dog to lay on. Your dog will not be stiff and sore when he arrives to hunt or perform in a field trail. The outer layers is 1000 denier cordura which is exteremly durable, the foam inside is wrapped in plastic so it is waterproof. You can rinse off the pads if your dog has an accident while in the box. There is a solid brass zipper on one end of the pad cover so you can remove foam and wash outter layer. The pads are alot cleaner compared to using straw or cedar chips. Everytime the dogs get out of the box it always drags out some straw or chips with it. Sizes: We custom make the pads so we will make whatever size you need.
