Great option for puppy before fully vaxed

This is the only way that I am able to take my pup out for a walk while I wait for her vaccinations to be complete. It is sturdy and great. Highly recommend. The only issue I have is that is really is impossible to put her in without having another person help me. It would be better if there were some kind of option to do this solo.

the backpack worked great for a long hike (~4-5 hours), but because of the dachshund body shape, the small size was too small to fit his length/chest size, but the medium size was too large in the neck area, so he kept slipping his feet out the top which caused for a lot of stops/readjustments

Comfortable and easy to use

Our dog loves this! She was comfortable, relaxed and the view as we biked to the beach so she could play in the sand.

The jury is still out, but it’s difficult and unnatural to strap a dog into one of these things. They’re very tight and it’s kind of like strapping a dog into a straight jacket. It doesn’t seem very nice for The Dog at all. I would have to say in all honesty, only use something like this for an emergency. Don’t let your Pet spend a lot of time in one of these things. This is definitely not what God created dogs for. If you’re going on a trip and your dog has to be strapped into one of these for a long time don’t go on that kind of trip with a dog. Dogs were meant to have all 4 feet on the ground.

I put my little Tobey in this backpack while visiting the Lakes Basin recently, and I was incredibly satisfied with the comfort for both him and me, even as he shifted from side to side and got excited about seeing wildlife on the trail. Highly recommend!

Runs 2 sizes smaller than normal

Sizing runs very small on this item. Material looked water resistant though, good for walks in light rain.

Really wanted to love it but so far it’s a no

I’ve had this bag for two days, did a fit test, and was excited it got here in time to try it out on a short mountain walk yesterday and then tried it for a short bike ride today. All three experiences were very uncomfortable. These seem like the nicest affordable bags on the market unless you are willing to spend $150+. The design of this bag is sooo bad. I got this for my 9 week old German shepherd pup so I can take her with me since she cannot go to public places and walk yet because she hasn’t been fully vaccinated yet. 1-No chest strap 2-there is a flat bottom but if you have to cinch any of the straps to fit your dog, it collapses and folds up against your lower back which is extremely awkward and uncomfortable. Then they dont have a sitting space. There is no ribbing or support to keep the bag in position or supported. 3-The side mesh doesn’t seem to help, she and I got super sweaty and she got hot and started gagging (it was evening and the sun was going down). 4-to get her to sit on my back where she needed to be-in order to be secure, I had to cinch the arm straps all the way down, which made my arm holes small and so hard to get the bag on because you can’t get your arms through. 5-it’s hard to take off as well because it’s so flimsy and there is no support so your dog is like a floppy burrito. Zero structure to the bag. It very much gives ‘drawstring backpack’ vibes with a bit more shoulder padding. Seriously. 6-I think she was uncomfortable because her arms were in the arms holes but her bottom half wasn’t sitting right 7-she started to wiggle and try to adjust and just started to try to climb on my head 8. I tried to loosen the straps to see if it would help her comfort and keep her from pawing my head but instead it just strangled her. 9-the photo makes it look like it’s supportive but it feels very cheap and is very flimsy and has very little support for carrying a dog on your back and your body begins to ache within minutes of putting it on. 10- huge bummer because I cannot see this bag being worn for more than 10-15 minutes at a time, which is worthless for an outdoorsy person. This seems like more of a novelty bag to look cute and get a photo, rather than a real bag to use for outdoor activities.

Impossible

I got this item for my puppy. I have acreage in the country and I can't have him running around while I cut the grass. I tried everything to get him in this carrier and nothing worked. I even had a friend help me but it still didn't work. So this item was a waste of money for me.

It not what I thought it was going to be. I have a medium and thinking about exchaning for a Large. I have a 14 pound Rat Terr and he doesn't seem comfortable in it. I'm a little disappointed.
