Dog's Black Coat Turns Gray with Vitiligo
25 Nov
Summary
- Labrador retriever developed vitiligo, causing fur to turn gray.
- Vitiligo is an autoimmune condition causing pigment loss in skin/hair.
- The condition is not contagious and does not cause pain or itching.
A heartwarming story of a Labrador retriever's changing appearance due to vitiligo has captivated social media users. The pup, initially with a completely black coat in 2023, began developing gray patches across her face and body by 2025, a result of the autoimmune condition vitiligo.
Veterinary experts explain that vitiligo occurs when the immune system mistakenly targets melanocytes, the cells responsible for pigment. This leads to a gradual loss of color in the skin and hair. While the exact cause is unknown, genetics likely play a role, and the condition can affect any breed.
Importantly, vitiligo is purely cosmetic and does not cause discomfort, pain, or itching for the affected dog. While depigmented areas require sun protection, no medical treatment is necessary. The condition's progression is irreversible in most cases, though the pigment can sometimes return.
