You just noticed that your pet has some spotting on their body, and your veterinarian informed you that it's from vitiligo. But what is vitiligo in dogs and cats? Here are all the basics.

What Is Vitiligo in Dogs & Cats?

Vitiligo is a rare skin condition that some humans may develop, but so can cats and dogs. A human or animal with this condition experiences depigmentation, which occurs when the skin loses its natural pigments. The skin will turn white (or light pink) in patches and hair in those spots can also turn white.

Tri-County Animal Hospital in Wayne, New Jersey reported that vitiligo is a "condition characterized by symmetrical lack of pigment in the skin and white hair coat, especially involving the face and nose."

What Causes Vitiligo?

Is vitiligo something that can be "caught" from another animal with the condition? Simply stated, no. Austin Veterinary Emergency & Specialty (AVES) confirms that vitiligo is not contagious. However, this condition is often hereditary, so if a previous generation experienced depigmentation, your cat or dog is more likely to develop this uncommon skin condition. It's not clear why vitiligo occurs, but it's believed that it happens when something interferes with the body's melanin-producing cells.

Are Some Cats and Dogs More Likely to Get It?

If you're worried that your dog or cat might develop vitiligo, don't be too concerned, especially if you haven't noticed any white skin or hair spots. This skin condition is quite rare, though there are some breeds that are more likely to get it than others.

Tri-County Animal Hospital noted that vitiligo is common in dog breeds such as "Belgian Tervuren, German shepherd dogs, Doberman pinschers, rottweilers, German shorthaired pointer, Old English sheepdog, and dachshunds." Siamese cats may be predisposed as well.
