After Rachel did my hair last week, we'd discussed trying to do the same to Atti.
She's a super sweet and trusting dog and had no problem sitting still while we worked on her.
The wet dye in her hair looked pretty amazing. She really resembled some kind of dinosaur. Unfortunately, we either didn't leave it in long enough or her hair just isn't super conducive to the coloring as it largely washed out during the rinse phase.
She does have a small blue mohawk, but we need to do some more research to do it corretly.
