He's almost 14 weeks old, and weighs around 2.5 lbs. He still fits in the bag fine, but I don't know how he'll fit if he gets over 5 lbs (which is the size I think he may be when he's fully grown)... Right now he fits in the bag perfectly. I still can close the bag even when he's standing straight or sitting down. The bag doesn't look very spacious with him inside, but he doesn't seem to mind (or it could be because he just wants to go out.. hehe).
The bag is 9" in height, but with its think padding (removable), the actually inside space is around 6.5" - 7" H. I'm a little doubtful that the bag would be able to support up to 15 lbs though... I think even 8lbs for maximum weight is already pushing it. But then I guess it also depends on how big your dog is. Hope this is helpful..
