Great pack for day hiking

My Wheaton Terrier loves this backpack and I like the fact that it tires him out a bit more! Great fit and look.

Boudreaux's Singletrak

We love this Singletrak Pack. I have tried other brands but this Ruffwear pack by far is my favorite. It fits snug and stays in place. The Singletrak is the perfect size for a long day hike.

Sweet pack

This is a great backpack! I’ve tried a few other packs before, but this is by far the best one. It distributes the weight well, is solidly built, and seems to ride comfortably, even over several hours of trail running. The included water bottles are also great (and can be frozen to keep your pup cool for a few hours). My only gripe is that the mouths of the bottles are too small, making refilling from water jugs a little difficult.

Good pack but unstable

Pretty good pack. Slides around a bit on my dog. I had the straps tightened as much as possible, but it still slides around. Also, make sure you take some water from both sides or the pack will really slide to one side

Perfect for day hikes

This pack is the perfect size for day hikes. It easily holds water, a lead, **** bags and treats. I bought a size medium for both my dogs. The fit is snug but comfortable on my 45 and 55 pound Vizslas.
