To make your own dog nose print gather the following materials:
Small piece of white paper
Damp washcloth or cloth towel
Saturate a piece of paper towel with the food coloring of your choice.
Gently dry your dog’s nose with another piece of paper towel or the end of a cloth towel and then dab the food coloring carefully on his nose.
Before he can lick his nose, gently press the white paper against his nose to make the print.
Set the print aside and very gently wipe the food coloring off his nose.
Food coloring used for human cooking will not hurt your dog. Just be gentle with him.
