Took a few days to get Popeye into the bag but after our first bike ride with his tongue out and him leaning over my shoulder as we flew down the roads of Costa Rica, he definitely enjoyed not having to walk on his short little legs!!
The bag is awesome, it fits him almost perfectly even with his long body and short legs and it fits very comfortably on my back with the padding and the hip strap since he is 14Kg despite his small look.
The only thing if I have to comment is I wish the bag was a tad lighter with the fabric material. But that's the only thing I have for a constructive criticism, we love the bag! Popeye loves the fact that he can now go biking with me or longer hikes when his legs give out on him :) Thank You K9 Sport Sack! Please continue to develop these backpacks!!
