It takes a lot of time but some are more natural 'riders' than others. Doughboy will sit on mine for hours, he's learned to balance with me when I bend over and pick things up. That took a lot longer because they love to run down your back and hop off onto the floor.
He's also the inactive type of chin, very food motivated and easy to train.
I think I might look into buying one of the bonding pouches, but do the chins stay in them?
