The Ruffwear Polar Trex dog boots are designed for warmth, traction, and protection in winter conditions. Insulated upper softshell fabric creates breathable, weatherproof warmth in extreme cold and inclement weather. Ruffwear-designed Vibram® outsole provides optimum traction on frozen surfaces.

Closure system combines hook-and-loop with hardware, cinching around the narrowest part of the dog’s leg to provide a secure fit. Pullover stretch gaiter keeps snow out and improves retention by protecting the hook-and-loop ankle closure from the elements.

Just as you would with your gear, adjust fit and check tension of boots 15 minutes into your activity and throughout the adventure as needed.

Living in Northern Ontario Canada. We have had an extremely cold winter (-40c) with deep snow. My dog loves the outdoors. I walk her everyday without fail. The boots have stayed on her running at full speed through deep snow and protected her feet nicely from salt roads and the cold. No issues getting them on her. She now gets excited when she seems them being pulled out of the bag casue she knows it's time to go.

Good product, sizing not right for my dog

I will start by saying that I love Ruffwear, and this seems like a super quality product. However, my dog unfortunately struggled with sizing. When I measured his feet he fell between the 2.25 and the 2.5. I ordered the 2.5 to be safe and unfortunately while the foot pad seems to be fine, they slip down his ankles and past his dew claws even when I tighten them as much as possible. And when I tighten them so much the strap/fabric bunches around his ankles in a way that rubs his ankles and seems uncomfortable on him. I have a friend who has the 2.25 and they fit his ankle better (and the velcro strap is actually narrower), but the foot pad is too small. I think he must just have big feet and skinny ankles. So, good product, unfortunately not the right sizing.

The Best Doggy Boots For Winter!

I did a lot of research on which doggy boots were best in winter for my Australian Shepherd. His paws are quite sensitive in the cold and salt up here in Michigan. The Polar Trex were listed as one of the best, and I would definitely agree! I am very pleased with them! They stay on his paws especially when he is running/playing hard in the snow, unlike the other boots I have tried. They are a bit expensive but totally worth it for protecting my pups paws! Thank you ruffwear!

Good. I used them on my springer spaniel when hunting late season (January 1-5, 2019) pheasants in South Dakota. It was winter on the Northern Great Plains. Temps below well zero and 8-12 inches of snow on the ground. Massive snow drifts in places. The boots did a good job of preventing snow from building up between his toes. They also protected his pads from frostbite. He did lose one boot the first day. The next morning I wrapped duct tape around the top of the boot and they stayed on the rest of the week. These are very good boots for working dogs. Jim Stutzman, Missoula, Montana

Great Shoes!

We have used them several times in very deep snow and frigid temperatures. Every time they did the job as advertised. I would highly recommend these shoes.
