## Questions & Answers

**Q: Has anyone tried to bring their dog in this on a plane?**
A: Yes, but please note you will want to checkout the K9 Karry On for a TSA approved carrier.

**Q: I have a 25# mini goldendoodle...is it difficult for 25#er's to be in these packs?**
A: I have a 20# Boston Terrier. She fits really well in this sack. I put a towel or small blanket  in the bottom for extra softness and for a little boost, when she sits completely down on her butt she’s a bit short for seeing out so the towel boosts her up. She seems comfortable and I think she feels safe inside. I’m able to take her in more places when out and about this way too.

**Q: When will the medium Air in jet black be in stock?**
A: It is in stock :)

**Q: I bought a large for my 18 inch long/23 lbs lhasa apso mix. she rolls into it. then the straps cut into my shoulders w/tingling.anyone else? thoughts?**
A: We appreciate your feedback and will forward these comments to our product development team.  Our AirPlus model has more padding in the straps as well as additional padding along the back of the K9 Sport Sack. Please keep in mind you should be taking breaks for yourself and your dog.

### ⭐⭐ Review
*by B***N on 19 July 2020*

While the K9 Sport Sack is a novel approach to carrying a dog, it is not suited to all breeds, especially those that have narrow airways like our pug (i would suggest that others like the Frenchie etc probably fall into the same boat. There is no support in the bag at all. The dog sits on the floppy bottom of the bag. Because there is nothing for them to push against, their legs get pushed up. Compressing into their body. The top of the bag closes around their neck. The bags are not well ventilated, despite the claims on the product description. We actually thought our pug was going to suffer harm. There was also no support for the wearer and you got to feel every part of the dog. Because there was no support, the backpack also sat low on the back. On returning the bag, we suffered insult added to injury. Not only did we have to pay duties because K9 Sport Sack is a third person seller, we also had to pay return postage. I definitely do not recommend this product for Pugs. As you can see from the photo, for just a few dollars more, we bought a proper child carrier backpack. This style has a frame and is much more comfortable for both the wearer and the pooch. There is support for their bottom and they are held in position by the same straps that hold a child in place. She loves it!
