There's a great book called "Elephants in the Living Room, Bears in the Canoe" which was written by a couple who trained animals for commercials, but also took in "waif" critters of all kinds, including a baby elephant which they raised in their house until she became to big. They also had a big old bear which was featured in later commercials for Hamms, in a real canoe. The book chronicles their misadventures in rescuing, caring for, and training animals to do such things.

Lots of used editions out there for sale and well worth the read, imo:
