My son & his girlfriend dyed our Jaxon last summer for a big race in Ohio to match our race car-She is a groomer & she used a human dye-they didn't leave it on him more than 1 min & he just now has a little bit of Lilac (it faded) left on the end of his topnot. I wouldn't recommend it unless you use the wash out stuff they use at Halloween. They didn't want him to get the color on us & the motorhome so they thought the 3 week rinse was o.k.-Well, if you wash your hair everyday it might go away alot faster. Here is the smurf!! He was defintley the talk of the 5 day race
