I have 6-year-old basset hound who loves to be outside. Unfortunately, in a Minnesota winter, his paws can't take the freezing temps very long. This means no walks in the winter, and on extremely cold days he can barely manage to go to the bathroom before his paws freeze. My wife and I have tried a couple different types of dog boots from REI, and Amazon.com without any luck. These boots were made with fleece insulation inside of thick canvas fabric with rubber soles. My dog absolutely refused to move one step with them on. We had given up hope on dog boots until I saw Pawz brand dog boots at a local pet store. Pawz dog boots are essentially large rubber balloons. There isn't any padding or fabric insulation, just bare rubber. We tried them out and after a very short period of awkward walking our dog forgot he was wearing them. The difference between these boots and other boots is that the dogs can still feel the ground underneath their paws. We were worried that with the lack of insulation, they wouldn't allow him to be outside much longer than without the rubber boots. It is obvious that the insulation of the more expensive boots isn't really an issue. Our dog managed to stay outside with these boots on for hours on a recent trip to U.P. Michigan, with temps well below zero. Unlike other boots that tend to fall off rather easily when the dog runs in the snow, we have yet to have one of these boots fall off. It also helps keep the very sharp salt on the sidewalks from cutting his paws or drying the pads out on walks in the city. Pawz dog boots are 100% biodegradable, and come in packs of 12. Even though they are considered disposable, we have yet to wear out our first set of four. They are extremely cheap considering the alternative, and are very easy to use --Tyler Coper Pawz Dog Boots $4 Comment on this at Cool Tools. Or, submit a tool!
