If you just google "cart goat" all manner of results come up. There's even a goat carting and packing forum.
It's actually really easy. We used to train all our buck goats to pull a cart so they had more than 5 minutes of work a year, lol. Then we didn't own our own buck for a while, but I just picked up a stunning little fella and I'm thinking he might just get a second job like my old crew. Basically, we just got them to love taking walks with us, then we did it with a cart, and slowly increased the weight.
My next door neighbor has a couple of goat's so I emailed the youtube link you just gave to her, and told her to make her goat's useful.
