I have worked with Elizabeth at Pro-Active Paws to set up a good dog boot for our UK trails.Over many months I tried & tested Pro-Active Paws Sled Dog Boots and know we have really good boots that last easy 8 times longer than anything I have seen on the market. My trails are the hardest in the UK: .rock hard in winter and I am hauling clients every day for a living. I need good foot protection!
