My husband and I went on vacation this past summer and left our dogs in the care of my parents (who both dogs see on a regular basis and are comfortable with). When we returned our rottie, Chief, had pink spots showing up on his nose. These were not present before we left and proceeded to get worse in the weeks after we returned. Our veterinarian could not determine the cause and referred us to a dermatologist. We also noticed that his eye lashes were turning white and he was getting little white hairs spread out all over his body. After doing some research of my own I realized the likely problem was vitiligo. The dermatologist agreed with this diagnosis but needed a biopsy to confirm 100%. Because the main symptoms were on his nose and around his eyes I did not allow the biopsy for fear of scarring and traumatizing him. Its not bothering anything physically. Its just a cosmetic issue. I am not concerned as long as its not bothering him. However, the white hairs are still popping up all over and now he has a white patch of fur directly under one eye. I was wondering if anyone else has seen this in their rottweiler and if anyone knows how long we can expect to see more little white hairs showing up? From my research it looks like stress is a trigger if the gene for vitiligo is present. Apparently Chief didn't like being away from us. I love Chief for who he is and could care less if he looks different than other rotties. I was just wondering if the white hairs will ever stop showing up. Thanks.
