Bought for a school trip in Auvergne (5 days) of my 5 year old daughter. Very well suited to his age issue morphology, although my daughter was not a big build. She arrives only to open / close the small clips (+ rabbat Fasteners straps). The large inside pocket closes tightly with a drawstring. The small front pocket is ideal for, eg, a packet of handkerchiefs + niceties of style bars! It hides a small label to be noted the child's name and a kind of plastic carabiner keyring.
The volume is impressive, there still was room with a complete change, a picnic and a bottle of 0.5L.
As for the little dog, it is very soft even after washing and appreciated my daughter !!!
