The terrain your dog will be exposed to both in your yard and on the road, are both a huge factor in the right type of dog shoe you need to get. If you have a simple lawn or pavement and need protection from rain, cold or mud, a waterproof silicon boot might be the right choice. If you are taking your dog on a long drive and their feet will be exposed to thick snow or cold conditions, you might choose the warmer fleece-lined dog shoes over worrying about treads. But if you and your dog face slippery conditions, sharp objects (like glass on a sandy beach), rough terrain, or muddy, cold snow, then a thick rubber soled dog shoe is a must to protect those paws from harmful environmental dangers.
