Can this be used on the front of the person with the dog facing forward? if not, is there a different option available for this position?

the pic shows a very big one and a smaller one what size is the smaller one or what size is the larger one??
Answer by ChewyApr 24, 2020
This backpack comes in 3 sizes. Please see attached sizing chart.

Does this keep the dog's back from rounding? Will it hurt them after a couple of hours? I have a dachshund and I'm worried he'd get back problems.
Answer by ChewyFeb 23, 2021
K9 Sport Sack carriers were designed under the close supervision of multiple veterinarians to ensure maximum comfort and safety. If the K9 Sport Sack is used properly, you should not have any issues with your dog's back. The carrier (except for size XS) is equipped with a lumbar strap for extra back support. However, if your dog has pre-existing health concerns or we recommend consulting your veterinarian before purchasing. During the consultation, it will be important to know your dog may stand on the base of the bag at first, but will settle in to sit in an upright position on their bottom. Their front paws will be exposed and resting on your shoulders. We recommend using the carrier for 30-45 minutes at a time.

How long can you keep your pup in this? Would it get too hot for them considering their body heat and their humans body heat? I’ve been debating on getting this for my 16 lb chihuahua but I live in a hot area and I’m worried about him getting too hot.

Best dog carrier!

I actually bought this through a small business at a dog event so it was easier to try on the backpack before buying. It’s perfect for: dogs that can’t/won’t walk long distances, if there’s a lot of blacktop during a hot day, if they’re tired, etc. My dog is 12 lb so we put her in a small and she LOVED IT! The weight was nothing and I only noticed when she wanted to get out (after 25 minutes). It keeps them snug with all the buckles and straps that do adjust for person AND dog. And it’s not just for small dogs! My brother in law also bought this (size large) for his 50lb pit Bull and the dog also loved it! Super happy with this purchase!

So far so good

Have yet to use it yet but did walk around our home carrying her in it to see how she handled it. It’s definitely a two person gig as I made my baby a bit scared getting her off of me. I wish there was a plus size option since the backpack feels so tiny. Lol I know it’s meant for my pet though. I just think it would help carrying her more comfortably for myself. The padded straps are cool but wish they would be thicker.

I love the idea , but not ideal for a 35-40 lb dog

My dog is around 37 lbs and has a longer body. She fits the large perfectly. Unfortunately, the bag doesn’t do a good job of dispersing her weight and it all localized onto my shoulders which is super uncomfortable (I’m 5’6” and 110 lbs) . Everything would be solved with a waist strap. I just wish this backpack was designed more solid and supportive, because it really does just feel like your dog is in a bag that shifts all over your back and hurts your shoulders . For the price I think it could be designed a lot better. That being said , it’s amazing to have the ability to take my dog on a bike ride , and for that it may be worth it .

Serves it's purpose well

We got this product so we could give our dogs a break when we cycle long distances, when we go to the city and have to take public transport and for tricky sections of hiking. So far we've used it biking on the road and on a ferry. The packs work exactly as described, the little pouch on this one is super helpful to keep necessities in and when the dogs are walking the backpack is easy to carry still. One big complaint is it really needs a waist strap, I know they put one on the bigger packs, but this one really needs it and the shoulder straps fit me fine but were a bit tight for my husband once he cinched the pack up to where it needed to be. This pack certainly made it easier to carry them when we needed to, but don't be fooled, you will definitely feel the weight. We have a 25lb dog (med pack) and a 40lb dog (large pack) and bought them each a pack. Overall I would recommend with the warning that this particular model of their packs is not likely intended for prolonged use, so if you plan to have to carry your dog for extended periods you may want to go up the the bigger packs that have more padding and the waist strap.

First bike ride

Thank you Chewy & K9! Dog fit perfectly in carrier and seemed happy and comfortable! Bike ride was about six miles on a paved rode with lots of shade. We didn’t want to go too far on the first ride and plan to use this on lots of short future trips.

Too small for me

The size L fits my 25lb bully/chihuahua mix pretty well. Unfortunately I’m a fairly thick 235lb weightlifter, and the bag straps cut into my outer back when tightened down properly. If I make them loose enough to fit me, my dog is not secure and hangs off of my back. The bag is great, IF you’re a smaller build person. Unfortunately I cannot use it.

Amazing quality!

This bag is amazing! It went beyond my expectations and has enough storage to put his water bottle and potty bags. He is alittle bigger so I do need to get a bigger size though.
