    So happy with it

    I bought the Air2, size medium, for my 13-year old 23 lbs pug. There’s enough room for him to still wear a sweater for extra insulation. He’s 14” long so he likely needed the booster but I just put a folded towel at the bottom and it seems to work well. I’ve worn the Air2 as a backpack and baby-bjorn style and both are very comfortable. I’m pretty sure he’s fallen asleep in it. I’m really happy with this purchase as it’s allowed me to go for longer walks and hikes with an aging pup.

    It would be nice if it had a waist strap to help support the weight. I find it harder on my shoulders than I expected even though our puppy is only 15 lbs.
