Sans Souciewrote a review of Ruffwear Bark'n Boots Grip Trex - Set of 4 on January 10, 2015
Familiarity: I've used it several times
Got these little boots for my mini aussie. Never in a million years would I agree to getting my dog boots, but they are essential. He isn't a dog that would allow you to cut the fur between his paws, so this is the next best option.
Initially putting the boots on:hilarious. Very awkward for a dog to have these on their feet, but I remained optimistic that he would get used to them. First day out with the boots in action, we went hiking in 2 feet of snow. I was a little worried he would stop and chew at them, but he didn't seem to notice. The only time I saw him stop to chew was on his wings of fur on his legs that I just need to trim or get the higher cut boot (polar trex). I would NOT suggest these boots if they are going at full sprint. I usually put the boots on for the hike up the canyon and remove them on the way down, since he is running/sprinting the majority of the way down. The first time I had him running at full sprint, one of them flew off. It was a good thing I had kept an eye on this, other wise I would have been SOL and had to buy another set to replace the missing one.
Also, would suggest getting the boot liners for added comfort.
