My dog, Pica, a Maltese can't seem to walk much. After 10-15 minutes, we need to carry him up.
The k9 air plus is good solution although it would have been nice if there's a support for lumbar and waist. If not, it can be a bit tiring.
The extra bag comes in handy. We can keep his water bottle and some of our items.
The only down side is it's so expensive to have it shipped here to Malaysia. Shipping cost is exorbitant. I forgot to purchase the block and noticed that shipping cost is more expensive than the block itself I ended up buying yoga block and cut it.
I love it.
