When it comes to your favorite West Highland white terrier or bichon frise, keeping her white at home may be a challenge. Yet after a trip to your favorite groomer, she comes home sparkling and looking whiter than fresh snow. The secret ingredient most groomers use to remove the yellowish tint your dog may display is actually blue.
How Does Blue Make White?
Bluing shampoos work by adding optical enhancers to the strands of hair. The human eye perceives these enhancers as white, making your dog look bright and brilliant. In addition, the blue hides yellowing of the hair caused by urine or licking.
When Blue Is Bad
While bluing shampoo helps to restore the bright white color to your dog’s coat, too much blue can turn your pooch into a Smurf. Shampooing too often or with too much bluing shampoo can tint your dog’s coat blue or purple. Bluing shampoo is not designed for sensitive skin, so dogs with skin sensitivities may not do well with regular bluing treatments. If you are just looking for a way to spruce up your dog’s coat for a special occasion, a little baking powder can go a long way. Sprinkle some onto your dog’s coat, work it into the coat and brush it out. This is often enough to return the fresh white look.
