The act of becoming camouflage requires the assistance of a Doberman puppy. First, I let the puppy practice pouncing, then jumping away from Rugby. It looks something like this -
Once the puppy has a few pounce/jump sequences under his belt, the Doberman gets closer and closer to Rugby. Eventually he leaves almost no room, and the big SPLASH he causes will coat Rugby with river water.
Wet Rugby hair is perfect for accumulating dirt, as long as you go where the dirt it. Rugby moves back to shore and Caesar followed to help with that part too.
After just a little bit of playing, Rugby starts to fade into the background. Soon, Rugby will be a completely brown dog.
That's all it takes! Just go find yourself a Doberman puppy and you will have a camo dog in no time!
