Ok I'm looking for a good shampoo for prissy. She has a long coat and to me it looks a bit dingy. I bought some blueing to try that out. I know it is safe for animals but it almost turned her blue I had to shampoo it out good. Do any of yall have experience with useing bluing? I thought I would just get a new shampoo with a color enhancer in it. what do yall use?
