I made this a few years ago and have made a few different ones since, the kids would request what animal they would like for there birthdays and we would sculpt using mostly water melons and other fruits that where in season. Since I made this a while ago I really don't have pics of the process.
Things I used to make the puppy:
2 watermelons one regular one and 1 mini for the head.
Bananas, oranges, grapes and other fruits and berries to full it up with.
I also bought a cheap dog harness at the dollar store.
You will nee a large tray to place it on as well.
It helps to have plenty of bowls and a good sharp knife.
You will also need tooth picks and some large wood skewers to hold the head on.
