Proof that "naughty spots" are earned - not just inherited
For a while we considered using ducks for training, so a friend brought his own ducks (Indian Runner crosses, I believe) for us to try. Isla was one of the dogs we picked for the experiment.
I used to think that females don't have as much sense of humour as male collies. I was wrong! In fact, Isla has rather more sense of humour than is ideal, as the ducks found out.
Of course, no ducks were harmed in the making of this photograph, but a few got into a flap.
