Fur color for cats and dogs is determined by their genes. Interestingly, there really are only two pigments: black and red. The rest are variations, and white is the absence of the two colors. Orange, brown and gray are dilutions of the two main pigments. All these other colors besides black and red develop because of mutations, modifiers and genetic factors.

So how does a cat get a permanent and natural zorro mask around its eyes? The science behind cat and dog genetics is pretty complex, but it generally comes down to dilution and coloration. A lot of the interesting markings on animals are just lucky ways pigment is distributed along the animal’s coat. The color of extremities ‒ face, feet, tail, ears, even nose ‒ can be influenced by temperature. Colder parts of the body are darker, while warmer parts tend to be lighter.

There are cases when strange markings on the fur can be alarming. The color of a pet’s coat might slightly change the older they get. New or unusual patches of color can indicate a more serious problem. Also observe the quality and thickness of your pet’s hair. If it’s diminishing or appears different from the usual, don’t hesitate to contact your veterinarian.

It’s a thing of true beauty to have a pet blessed with a unique fur pattern. Sadly, not every owner is so lucky. What to do if your furry friend lacks that oomph in the looks department? Custom looks can be created with pet outfits and accessories. Pet stores offer a wide variety of animal apparel. From sparkly bows to elaborate human-like suits, it’s now possible to play dress-up with your pet. Then again, what if you want to match your pet’s outfit to yours and that hot dog costume on your dachshund just isn’t enough?

As three different veterinarians have told Allure, it is medically safe to dye your pet’s hair. As long as non-toxic dyes are used, there should be no harm to pets. Although there is a moral dilemma: the coloring selfishly only benefits the owner, so should it be ethically okay? As with most things when it comes to our pets’ wellbeing, experts advise us to observe their behavior. If your dog or cat doesn’t like the process of getting their fur colored, they will surely let you know.

There are some things to look out for if you’ve decided to color your pet at home. Neater Pets advises to never use human hair dye on animals. If you’re determined to give your pet a colorful makeover, be sure to use dyes that are not permanent. Safe to use are natural food coloring, Kool-Aid or fur chalk. Permanent human hair dyes can contain bleach or hydrogen peroxide. Using those on your furry best friend might result in increased shedding, skin irritation or even chemical burns. Also keep in mind that your pet might ingest the dye that you’re using when licking themselves.

Natural food coloring is made from vegetables, fruits or flowers and shouldn’t pose any threat to your pet’s coat and skin. Kool-Aid is another safe option. This method works best on lighter-colored fur and will fade out in around two weeks. The shortest-lasting makeover you can give your pet is with fur chalk. It washes out easily with shampoo and is designed specifically for fur dying.

The safest way to color your pet, of course, is to go to a professional. Groomers that are trained in coat dying will take the best care of your beloved fur ball. It’s guaranteed they’ll use only non-toxic products that will cause no harm and will make a lot less mess than you would in your home bathroom. The aesthetic outcome should be more pleasing as well, after all, these people are experts and have years of experience doing this kind of thing.

Creative grooming in itself is not a new concept, at least in the world of dog owners. The American Kennel Club does not oppose dying canines’ hair, yet they strongly advocate for doing so responsibly. They emphasize that professional groomers should complete appropriate training prior to getting licensed.

Some states in the US have banned dying pets’ coats. Among them are Colorado, Florida, Maine and South Carolina. Check with the local authorities if your pet’s new look can cost you a fine or lead to your pet being taken away altogether. There’s reportedly some leeway when it comes to enforcing these laws, but it is still technically illegal.
