When a dog gets sexually excited, it's cock grows, much like a humans. However, a dog's erection often resembles a lipstick tube, scarlet in colour.

What a horny dog gets. The males are the only one who experience this. It is just a dogs erection and it looks like a pink lipstick. Stay far away if your a man - the dog may start humping your leg. If you are a girl - dont us the lipstick.
