Goats Love To Shop Too

I always remember just seeing goats at farms, but now I guess you can even see them at Walmart. Not only is this man bringing a goat shopping with him, but he is also bringing it in its own little wagon.
What would possess someone to bring a goat to Walmart? I get bringing a dog or a therapy pet, but why a goat? Maybe he thinks of the goat as a dog or pet, but what’s next, bringing a horse, cow, or perhaps a pig?
