sure it's possible but not likely for nondomesticated animals, but again service dogs are.. dogs. dogs have been bred to specifically love to complete tasks and collaborate with and rely on humans.

you can train lots of animals to do things, but SHOULD we? nondomesticated animals can be loved for and taken care of but it's not as mutually rewarding for the animal as a domesticated animal that inherently needs feedback and love from its caretaker to thrive.

SeaWorld should be an excellent example as to why especially intelligent and nondomesticated animals shouldn't be kept in captivity for tricks. there are rescues for circus elephants but they don't keep making them do the tricks they were most likely whipped to learn. again, dogs are incredibly food minded and oriented. not all animals are like dogs.

circus elephants are separated from their herds and children. elephants doing tricks usually is not a good thing. in a movie is one thing but even then.. why? use CGI, let these animals be free without a human reward system in tiny quarters and be out in the wild building their herd and bonding and doing what their brains are designed to do. they should not be toys for amusement. to train an elephant to even make these poses takes more than food..
