My wife has a little black Fiest that goes fishing with us. She will sit there on the bank and watch my cork (sorry, this is while drowning worms with the wife) and will stand up if it starts bobbing under. We have to be careful bringing our hooks in so she doesn't jump up and grab them.
Every once in a while we will throw the small ones in the shallow water at the bank so she can chase them. If they scooch over a foot from where they land, she will look at them and keep right on pawing at the spot where they hit the water.
A few have squirted back up to the edge of the bank where she can get to them, and she tries to pick them up with her teeth. She just ain't real sure she wants to bite them, cause they wiggle. It's hilarious to watch her, because she takes it so seriously.
