At the end of 2021, Buster, who was two years old at the time, was diagnosed with vitiligo. Vitiligo is a condition triggered by an autoimmune disorder that results in the loss of pigment in various parts of the body such as the skin, hair, snout, lips, as well as the oral and facial mucosa. This is the story of Buster, a dog affected by vitiligo, quoted from odditycentral.com on (29/4).

Matt Smith, who became the owner of Buster, was asked to pay attention to signs of irritation on his skin, but assured that Buster's health would not be affected. Currently, Buster has undergone a change from dark black color to clean white. A few years ago, Matt Smith shared his experience on Reddit, showcasing Buster's face transformation over a period of nine months since he was diagnosed with vitiligo.

"I will not believe in it without evidence of its transition," said an individual. "Very interesting! This is the most captivating content I have come across on Reddit in a long time. Initially, I doubted its authenticity, but after I investigated," wrote another person. When looking at the before and after pictures side by side, it is almost impossible to recognize that it is the same dog. Although its eyes remain similar, the changes it underwent are very striking."
