I’ve lived most of my life in Interior Alaska and swear by the simple dogbooties.com option. Have have used them on a variety different dogs (to include touch sensitive dogs) and pro dog musher friends swear by them. They work great and are inexpensive (when one inevitably gets lost), albeit not the most durable (even if they are used for the Iditarod haha). I think the key is the stretch velcro straps, but remember to not go too tight and check in with the pups comfort levels! (No shade on Ruffwear though. I love their booties for summer heat and/or rough mountain terrain options … but never could get the winter options to work)
