Designated sock remover
I have a two year old Rottweiler who is the families designated sock remover. Just ask her to take off your socks and she will gently find a little piece to pull.
Then with a good grip she will tug until the sock is off. When she's being silly she will try to take them off while you are walking and wearing them.
She will trip you then take off your socks and then put them on her bed.
