You've got enough to carry already.

There’s no free ride for Fido when he hits the trail; he's carrying his own grub and gear in the Mountainsmith Dog Pack. This pannier-style pack is secured a fully adjustable three-point-padded, fleece-lined harness with a removable chest pad that ensures a comfortable and stable fit; the pack's tapered torso profile reduces drag and improves your dog’s balance as he trots down the trail. Attach his leash to the D-ring on the top of the harness as you waltz by the Animal Control officer lurking by the trailhead, and store it in the internal pocket once you’re out of her sight.

  • Two zippered pockets with rain flaps carry grub and water for the day or weekend
  • Single haul handle on the top of the pack enables you to quickly grab your dog when you spot a mountain biker barreling down the trail towards you
  • Elastic bungee attachment point lets you strap extra gear on to the top
  • Side compression straps keep the pack from slipping around as he bounds after a rabbit
  • A generous application of 3M reflective trim keeps your pup safe in the parking lot at twilight

Styling Pack (If your pup will tolerate)

  • Familiarity: I've used it once or twice and have initial impressions

this pack will be great once my pup learns to love it as much as i do. right now he's a houdini and escapes each time i strap him in. he was 5mos old when i got it so i'll give him a few more months and try again...

Perfect for the Backpacking Pup

  • Familiarity: I've used it several times

This has been a great pack for my pup and I on long trips. Uinta doesn't ever mind to put it on, has never developed any hotspots using it and seems to have the same amount of energy with it carrying 7 lbs as she does with nothing on at all. It great to have her carry her own food and bedding as well as my trail snacks (which are much easier to get off of her than they are to get out of my pack while on the trail). A must have for anyone backpacking with an energetic and healthy pup.

Heading up the skin track on a fresh POW day at Berthoud Pass, Tuckerman is ready with his Mountainsmith Dog pack. He's got his water and snow boots in there and soon my skins...What a great ski partner!

The Pup Seems to Like It

Kody seem to really love this pack. This is the first time he's used a hiking backpack. The medium size is a little big for him (he's 45-50lbs), but he carried two water bottles, his treats, and water bowl without issue. The only thing that I noticed on him after our hike was an irritated area on his front, inner leg where the buckle is located...other than that I think he enjoyed carrying his own weight in water :D

Excited for the possibilities!

  • Familiarity: I've used it once or twice and have initial impressions

This pack seems great. Two fairly large pouches, a large handle if the dog needs a lift, and the adjustable straps are padded so that should be nice for the dog. There are two straps that goes across the belly of the dog, one that goes across the chest and one that connects that chest strap to the first belly strap so the pack isn't going anywhere. The one downside I have found so far is that the padding on the straps on the belly make it a little difficult to adjust them. I haven't had much of a chance to put it to use but I will update when I do.

I bought this in size medium for my 45 lb dog, and it fits pretty well, slightly loose but he should grow into it very easily.

Excited for the possibilities!
Responded on

I Love the look of his face. He's like "WHAT, WHY" does this pack have a place to put cold packs on the inside of the pack to keep the dog cool in the summer?

Responded on

Ha yeah he is still getting used to it, but as far as pockets for cold packs, there isn't anything specific for them but you could probably make something work with the two main side pouches.

I hope that helps!

We often have to lift our dog (about 50lb)...

We often have to lift our dog (about 50lb) over really large boulders. If we were to buy this pack and then use the handle to help lift her, would this pack be strong enough? or would it tear the stitching/fabric?

Responded on

I wouldn't recommend using the handle on the top of the pack as it is designed more as a large grab loop to hold your dog in place, not for lifting. The stitching and fabric is durable but the buckles are still only plastic, so likely picking your dog up by the handle would be very uncomfortable for the pup as well as putting significant stress on the plastic buckles. You could likely get away with lifting by the handle a few times, but I wouldn't recommend it's repeated use. Something like the Ruffwear Doubleback Harness is a much better tool for the job of lifting a dog by the handle:

Best Answer Responded on

I am the Mountainsmith Rep. The buckles are extremely durable and can handle the lifting you describe. The handle is constructed of nylon similar to that used in climbing harness and is bar-tacked multiple times again similar to climbing harnesses. The handle can manage this load easily and you should have every confidence in it.

Keeps us hauling

  • Familiarity: I've put it through the wringer

This is a great accessory pack for your dog. It is light, easily harnesses, and stays in place. A great way to have your dog carry his own weight in backcountry endeavors or just a quick jaunt down the trail. I think this product is great for my pup in the cooler months of the year. SUmmer forget about it, dogs have long coats and could potentially overheat. They already have a fur coat, why give them another one. This bag is well designed and allows a dog to carry just enough weight not too much. Again I would recommend for cooler months. I usually put mine on my dog when we are backcountry skiing and I am bringing extras for him, but other than that would not see much use for it.

Perfect dog pack!

The harness system is fully adjustable with 3 padded straps, it creates a secure fit to your doggie. My dog looks comfortable in the pack and it's never phased him. It's nice for him to carry his own food for our backpacking trips, I will usually put our trash in the pockets for the hike out when he has eaten all his food. Keeping the weight equal on each side pocket is key. They say dogs can carry up to 40% of there weight. Nerf dogs weights 100 pounds and he carried maybe 10 pounds for 30miles, didn't phase him!

Love this Doggie Pack!

Our 60 lb. female lab wears this pack in a medium. Easily adjustable to accomodate different sized dogs.

Mountainsmith Dog Packs

We've taken our 30+ year history of making dog packs and updated them for Fido's next season in the backcountry. A fully adjustable 3 section padded harness system insures a comfortable and stable fit as your best friend runs over hill and hollow. A newly tapered torso shape reduces ground drag and increases balance to follow the natural way your dog moves along the trail. Rounding out the package is a safety minded application of 3M reflective tape; great for those late night treks back to the car after a day of chasing rabbits. Available in 3 sizes - S / M / L.

Medium on the AT

I have a Belgian Malinois that carried his own food and water for 100 miles on the Appalachian Trail. I also suggest letting the dog carry the trash as a long hike progresses since he's losing pack weight as he eats his food. *Make sure you practice with your dog and the pack with weight first so his pads are use to it and so is his back.

Dogs backpack

This backpack is just the right size for my 69 pound Black Lab who is my guidedog; I am legally blind. The pack goes onto "Gerty" first, then my Guiding Harness Assembly; the pack doesn't interfer with Gerty's guiding ability. I can carry seven two cup (in individual ziplock bags) of dry dog food, enough treats for seven days, and also a liter of water, not enough for the full week of camping, but less weight that I have to carry. I am very happy with this backpack for my dog, and would recommend it highly to others who enjoy hiking and camping with their dogs.
