The farmer, his children, and their pets

A farmer, his son and daughter and their pets need to cross a river. The pets are a fierce dog, two hamsters, and two rabbits. There is a small two-seater boat that they can use. All three people can row the boat, but none of the animals can.

If the farmer is not around, the dog will bite everybody and everything.
If the son is not around, the daughter will tease the hamsters.
If the daughter is not around, the son will tease the rabbits.
The hamsters and the rabbits get along fine with each other.

Help everyone cross the river without any biting or teasing.

This is a problem on the web (http://freeweb.siol.net/danej/riverIQGame.swf). The instructions are in Chinese and the setting is a bit different. To start the game, click the big blue button. To move the people, click on them. To move the raft, click on the pole on the side of the river.
