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.

My dog came right out of them so I went a size smaller and then he wanted to rip them off after walking about 30 yards. I was very disappointed because my dog gets ice balls between his pads in the snow and was hoping these boots would save our problem.

Had some issues

The first pair I got would stay on my dog's back feet but not the front. Lost two in deep snow. I bought a second pair a size bigger for the front paws. They stayed on better but fives hours into the hike I had to take them off her so she could have more traction. The zippers had iced up and I used hand warmers to get them off. I found she had sores on her front feet and was upset with one of the back booties. She descended with one boot. Still haven't figured out what I'm doing wrong. On the other hand, our RuffWear back pack is awesome. I recommend that to everyone I see with a dog in the mountains (although I'm seeing more and more people who have bought one)

Great boots!

Great material and quality of boots. A little hard to get them to stay on at first since your learning how to put them on properly, but otherwise once you find the right tightness for your dogs paw great fit!

Polar Trex for a 11-pound Cockapoo

Great! He’s been wearing your boots for 11 years...since he was a puppy in Minnesota.

They seem to slip off

They seem to slip off a little bit - the first time they fell right off, and the second only one came off. Probably user error/figuring out how to fit them best. They keep my pup's paws dry and warm, which is really all I care about! He's got longer fur so when we adventure in the snow his paws turn into snow and ice balls, so these allow us to stay out longer and not have to worry about that!
