Dog Backpack for Medium & Large Dogs, Nylon Backpack for Dogs Tactical Pet Backpack with Side Pockets for Hiking Walking Training Running (Brown, Medium)

These have been great packs for day hikes with my dogs. I like that they Velcro down across the chest and hips so you can get the perfect fit. Seems to be comfortable for the dogs and didn't have any hot spots or rubbing after several hours of use. Bags are large enough to carry a couple of liters of water (I used collapsable water bags), a collapsable bowl and some food. The medium size pack has smaller bags than the large size. One con is the buckle straps are hard to adjust, but once you get them dialed in you shouldn't have to adjust them again after. They seem to only be there for extra security on top of the Velcro straps. I did originally think the bags were removable from the vest but turns out they are sewn on. Packs have extra Velcro and some molle to attach small gear or patches. Overall, a very sturdy pack at an affordable price.

I’ve had this backpack for my dog since April 2025 and it is now July 2025. We have used it about 20-30 times and it is very sturdy and great quality. Zippers still unzip and zip up easily. My dog seems comfortable with it and loves to wear it for walks. I like that it fits only the upper body of the dog, keeping pressure off the hips and spine. Holds two 32oz Nalgene bottles, one in each zip pocket, and then I ordered collapsible bowls to clip on.

Took my dog on an overnight winter backpacking trip and used this for the first time. We both loved it. The straps adjusted well. I have a 75lb Bernese mountain dog and she fit at about the tightest setting of the large size. I like that it has a handle, it fits her food, bags, water and a small blanket for her. The orange was also nice because it was easy to see her. Great value for the cost.

I must've looked at 100 harnesses for my guy. Wanted something comfortable for him that was a good harness 1st and foremost. If it had some extras that's just a bonus... since the price wasn't too high I figured I'd try this one out. aside from looking amazing on him it fit perfect right out of the packaging. I literally didn't have to adjust the straps (which are easily adjustable, I did mess with them eventually). When I strapped it on him you'd have thought I magically gave him his balls back, he pranced down the bike trail with sincere purpose. He can run in it no problem, doesn't rub or hinder movement. I'll have to see how he likes it when it starts getting hot outside, might be something a little too bulky for the heat, not sure yet. Nonetheless it'll still be my go-to 9-10months/year if it's too hot during the summer months. Patches and flashlight sold separately, but the elastic molle bungee system tightly secures the flashlight (shake proof!) 4 out of 5 stars because it's brand new, if it holds up to wear and tear it'll garner 5 stars imo. Update: 7/24/23 it's not too hot for him, he still loves it, wears it every day and the harness is holding up great.

This was a Find which made both of us very Happy! This OneTigris Mammoth Back Pack is exceptionally WELL-MADE! Quality features and well-manufactured. No flimsy fabric - strong and durable woven nylon, with a mesh lining. For this Remarkable Price ! And . . . I sew! so I know Quality when I see it. What sets this Mammoth Back Pack apart from its competition was the comfortably-wide Straps in front of and around the dogs chest, instead of nylon webbing to cut the dogs skin on long treks. The side Pouches are a perfect size, complete with a grommet in the bottom of each to drain collected liquids, from rain or from fording rivers. The MOLLE webbing next to the Handle is stupendous for securely attaching more equipment, and the hook-&-loop on the Pouches is perfect to display various Patches. My immediate modifications included: shortening the nylon strap ends slightly, so they don’t flop, and the bungee cords were removed to serve another purpose. Copper is a German Pinscher. Her Neck girth is 15" and her Chest measurement is 24", (Suggested minimums: Neck -18"; Chest - 25") so I was a bit hesitant because she is smaller than the minimum measurements for this Back Pack. When I ordered it, having sewed a LOT over the years, I knew I could adjust this Back Pack to be a bit smaller as required. . . . . NEVER MIND - it fit ! Before it ever arrived, I talked this Mammoth Back Pack up to the dog, telling her how wonderful her Back Pack is, and how pretty she looks with it on. Fully adjusted to its smallest size, when I tried it on her, it fit quite well - maybe just a teensy bit too large. Despite it was designed for larger dogs, the Pouches fit her quite proportionately. Small as she is, she loves prancing around in it. Shearling boots, bought in West Germany in 1971, with plastic soles & heels, were harvested when the soles disintegrated with time. The shearling was still in excellent condition, and just one piece from the calf, was hand-sewn on the inside of the OneTigris Mammoth Back Pack. Now, the added bulk from the shearling softly pads her lower chest, and it fits her snugly. With the Back Pack on, she is still able to run like the Wind, and to jump over the rear tailgate into the back of her car. And the Coyote Brown color blends perfectly with her coat. She uses this Back Pack as a Trained Service Dog. Buy this OneTigris Mammoth Back Pack with Confidence ! April 2022 UPDATE: This California, German Pinscher, wearing this ONETIGRIS Backpack off & on, while working, for over a year, she attended an internment at Arlington National Cemetery, and traveled on ten airline flights. She struts around when she has her work BackPack on, and the Packs contain her longer cord leash, poop bags, treats, and large "Hothands" body-warmers. Also added more shearling to the front chest straps for added comfort while in a DOWN on airliners. Everywhere she goes in her ONETIGRIS Backpack, she is the center of attention.

I'll keep it short and sweet. This thing is pretty much perfect. Fit perfect. Look perfect. It fit my 25lb rather lean pup wonderfully. This was his first time wearing a vest, a load, and backpacking all at once, but he didn't skip a beat. I had to pick him up several times on the hike by the vest handle, and the underbelly support perfectly cradled him. He never squirmed or acting uncomfortable. It's a rugged canvas material, not the most breathable, but wasn't an issue for Theo and I expect it to handle years of use and abuse. Appropriately sized pockets. We were near a few cliffs and the plastic rear leash attachment had me uneasy. I would like to see that metal and with more reinforcing stitching.

Definitely built tough and rugged. I’ve had mine for 2 years and only thing that’s happened is the color faded from the sun and elements. I’d definitely buy this again.

Our dog is an XL bully at 100lbs. Fit him like a glove and we use this when hiking or running. Doesn’t rub and leave spots. Super easy to put on.

Delighted with this doggie back-pack. Zoe our marvellous adventure doggo wore this every day on holiday on the Isle of Arran. She carried her own water bottle and poop bags (both unused and used) in one side and another spare water bottle in the other side. You need to keep the weight even on both side, but this was easily done. The padded area under the clip in front of her chest was needed. Other products don’t have this which is why I bought this one. It’s a must when running when keeping up with us on our mountain bikes. Thankfully there are 2 small water drainage holes in both saddle bags - ideal for Zoe as she frequently lay down in water to cool off when wearing the back-pack. Very happy with the quality, it dried quickly too. She was always happy to put it on - she’d see it and get excited, knowing that it meant we were heading into the hills for the day.

The product is really well made, we haven't tried it yet but it looks rugged, the only issue is the size, unfortunately it's too small for my Greyhound =(

I have had this pack for my senior pup for about a year now. We have received many compliments on its aesthetics and questions about its functionality. I live in Northern Canada where I take the dog out for many hikes in varying terrain and this pack has caused no pain for my senior dog. Even with slight imbalances in weight on either side, the pack seems to remain balanced and centered on the dog — this being said I have no gauge of actual measured weight. It seems to be once that proverbial scale has tipped, the bag becomes rather off balanced. I wish the Velcro belly was a bit more friendly for barrel chested dogs. While I have no issues fitting the harness, where the Velcro pieces overlap I do find some irritation underneath my dog's fur (double coated dog) and have to be very particular about the way it is put on. Elastic sides are great for putting certain gear in or clipping things on like a collapsible water bowl. That being said I find these things are always getting caught and snagged on anything and everything. From tree branches to chain link fences. I do love this harness though, and think it's particularly well made and look forward to purchasing other products from onetigris in the future!

When I decided to buy this harness, I knew I was investing in quality—I’ve owned this brand before, and it’s never let me down. My Malinois, a hefty 35kg, needed a large size, and it fits him perfectly with plenty of room for adjustments if needed. The generously sized pockets are a game-changer, taking the load off me during hikes. It’s designed to be effortless to slip on and off. Built from durable, high-quality materials, this harness is not just functional but also excellent value for money. We are due to hike the WHW next week therefore I purchased some goggles to help protect his eyes in the wind and rain.

Good fit for my 1 year old Samoyed
