Hog is signed exactly like pig: put your hand under your chin and bend your fingers at the first joint a couple of times. This reminds us of the sign for dirt or dirty.
Put together a collection of farm yard animal flash cards, and play a game making the signs. Even better, take your baby down to a farm yard. Another great thing to do with the farm yard signs is to sing a song like, "Old MacDonald Had a Farm".
Do some oinking and snorting as you show the hog flash card, to help make the learning experience more vivid.
