We have the option to upgrade our wooden dog kennel and runs to have PVC lined insulation. This involves adding polystyrene between framework and then lining with 2mm PVC sheets. Each PVC sheet is fixed with poly headed pins along the outside edge and also up the middle to ensure a sturdy and reliable application. Dogs who are prone to chewing do so when there is exposed framework, so lining with PVC removes any opportunity for them to get their mouth round any of the framework. Other materials can be used such as plywood or Stockboard, however we find that lining with PVC is best as it provides an anti-bacterial and wipe clean finish. Beware of seemingly new-to-the market materials such as thin metal sheeting as it can easily cause severe injury to your dogs. Especially when cut straight with a guillotine, the edges are left sharp and potentially hazardous – think of a tin can when opened. Please consider your options carefully when buying your new dog kennel and run. We are a business and obviously want to make money from it – but never at the cost of your dog’s safety. If you do require any more information please get in touch.
