We have a Cavalier King Charles and found the small backpack was a little too large. We purchased a cushion and now he fits perfectly in the Backpack.
My sport sack is a size large, my dog fits perfectly in it when we ride bike. However, if we go for a walk she would sit a little too low. The booster block fixes that problem. If your dog, like mine, is in between sizes or just doesn’t sit quite right in the sack I would look into the booster. It’s definitely worth it.
