This is my new product. it is called Pet Chalk. Pet Chlka is a temporary color product that works on most coats including dark coats without the need to pre-lighten the hair. To use spritz the hair slightly with water, then place hair between your thumb and the color pat and gently move thumb back and forth rubbing the color onto the hair. You can then use a flat iron to seal it in to make it last longer. Another method of application is to rub your finger onto the pat and then transfer it to the dogs coat by rubbing it in. Make up brushes can also be used. The Pet chalk will usually come out of coat in one or two washes.
