Take a look at the picture above. Back in 2006, Hotels.nl, an online hotel reservation company in Netherlands used the sheep for outdoor advertising. They displayed their logo on royal blue waterproof blankets worn by sheep.The company sponsored about 144 sheep in flocks throughout the country and spend 1 Euro per day per ship. It was a creative idea. But, I think that using animals as advertising billboards may not be an acceptable idea for all. What you think about it?
