High quality pack with long adjustable straps. Apollo loves that he is now able to carry his own water bowl, emergency first aid kit, fido pro, and treats. His mom loves that he can also carry out his own waste bags too!I love these saddle dog saddle bags. They look great on my birder collie. With a water bottles on each side, and weighing a total of anout 2.5 lbs, she carries them like they are not even there.We will be doing lots of hiking to build up strength.Great product and idea. I wish I had known / thought about them before now.We clipped one of his tags on the zipper, balanced the pack, and everything went grrreat! More than enough room for what I carry, but now Thor is old enough to help. And he did a great job being of service. Thank you for a great productI got this because I am lazy and I have an energetic dog that likes to hit the disc golf course with me. I can easily put 4 discs in each side, and the side pockets can be zipped with them in there. 5 on each side could easily fit. There is room for a small bottle of water in each side if there are only 4 discs.This fits perfectly on my dog and he loves wearing it. I place his waste bags inside the zip and when we went up to the top of a waterfall I packed it with two bottles of water along with his waste bags. I would recommend this product, the quality is great and the price is great as well.We use this for day hiking and are really happy with it. My dog has used it a dozen or so times now and haven’t had any issues. I haven’t packed it super full to see how it holds up but it helps him share a bit of the load on day hikes. The material seems to be good I will update if it doesn’t last but so far so good.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-wideStraps 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 Handleis stupendous for securely attaching more equipment, and the hook-&-loop on the Pouchesis 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 Packto 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 wonderfulher 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 harvestedwhen 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 tailgateinto 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.This product is great and does the job I wanted. It has got lots of flexibility for adjusting the size because you can use both the Velcro on the front and the underneath.You can get quite a lot in there my dogs carry water bottles that is their job. They are Border collies and love a job. My dog is happy to wear the backpack and so I give high comfort rating but I have had to and would STRONGLY RECOMMEND others to Remove the bungee cord that goes around the outside of the backpack!!!We love some off road hiking and exploring and twice my dog has got caught on undergrowth and some fencing. Now she is very clever and has yipped to alert me and I have rescued her but this could be VERY DANGEROUS!I hope this is helpfulDelighted 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.I'd say this is a great piece of kit. Although they put the strap on the right side, meaning when dog walks to heel looking up it does dig you in the leg. Not so fun. Size is a tad off round the chest.However, the bag is sturdy, strong and very well made. I really like it as it holds a good amount and dog seems to like carrying it. Velcro for patches is cool too. Overall great product which needs some minor tweaks!Would buy again.Very happy with the fit and quality of this item. My 30kg bull lurcher wears it well and seems very comfortable in it. Can't wait to hit the trail!Smart, and doesn’t budge even when we run for miles with dog bolting into the sea on a regular basis for a swim (with kit in waterproof bags in the pouches). Dog looks proud as punch carrying all his gear and half of mine. Larger fit than I expected but just fits my large border collie on the absolute smallest setting the belly strap can go (large size). Medium would have been better.
