On Petz Dogz 5 Catz 5 how do you get youer petz back to there normal coler

Give them a bath (wash, scrub and dry) after you dry them they should have there normal color back =) No a better way is to:
When you click on the suitcase click on the picture of the dog (next to your dogs name) and, next to spray/neuter click restore original colours!
Or you can do it the way that person said but you dont need to give them a bath just put the towel over them ! :D
