Yes, Janice, they sure can. My dog actually uses the "fake dump" to stall for time on our walks. He'll do the tell-tale sniffing around in small circles, look as though he's about to do the deed, and then -- change his mind! And then he goes off to sniff the bushes he really wanted to investigate in the first place. It drives me nuts! Sneaky bugger....
