    Can't live without it

    This is actually our second K9 sportsack air... We actually wore out the first. (We have used it countless times over four years - probably 5x/week most of the year.) My dog is crazy about it; he tries to climb in by himself and is beyond excited when I say "backpack." We use it mostly for bike rides, with the snuggie for winter rides, but have gotten into using it on walks this year, too. It's really convenient, and we find it very easy to pop him in and out, usually multiple times on a trip. The zipper guard is much appreciated, as my dog has very long hair. I never imagined it would be such a success and something we cannot live without... Love our backpack!

    Sizing is off?

    According to the measurements my dog should be a small, so I ordered that size. However, it is way too small for her. I have reached out twice now to exchange for a medium, and have yet to even receive a response. Between the sizing being off and exchange/return not being possible, I am feeling kind of ripped off and will be contacting my credit card company next.

    Works great!

    Works great for my little pal and I don't have to leave him behind when I do my exercise walks and my bike rides. He loves going with me and having the wind in his fur. Thank you for making this possible and for producing a well designed product which is second to none!
