I've had this backpack for 2 weekends, logged 25 miles over rough terrain and it's working great! We tested it out empty for the first ride, then added 2lbs for the 2nd and now he's at 5lbs. That's probably his limit; he weighs 43 lbs. Today we went about 9.5 miles with steep elevation changes. I checked it periodically to make sure there no rubs or sore spots--nothing! It rides very stable and does not slide.This pack is very adjustable to get a snug fit, can carry a variety of things--2 water bottles will fit in each pocket.It's been wet and muddy, run through dense brush, and seems to be holding up fine.I love the handle on the back! Since I am on a horse, the handle gives me an easy way to lift him in case I have to pack him out in an emergency.I can't say Jasper loves it, but my horse really appreciates not having to haul her little predator's crap everywhere!Well designed, well made, and well priced!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.I love it but it fit my Boston terrier a bit big! I got a size medium but I’m exchanging it for a small size instead!I 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.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 productThis 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 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.
