I picked up Sunday from ToysRUs a Tiger Electronics Mio Pup robotic dog. It can walk forwards and has 4 capacitive touch sensors, a touch switch on the nose, motorized moveable ears, legs and tail. Also has LEDs all over it as well as two large eye LCDs.
It can display 100 different eye patterns and talks to you in a babbling language and can hear you with a built in microphone. It comes with a magnetic bone that magnetizes to it's mouth for pretend feeding.
It has a full compliment simulated emotions, and a sleep function. But strangely no off switch at all. Here is a link to see it.
It is not as good as my Roboquad, but it is much, much more interactive though.
