Hi my six month old staffie has seem too of developed a small tiny spot on the top of her head. Is is redish in colour and call me pathetic but its about 3 mm. I know its not huge or anything but it seems to be growing and moving the direction of hairs around and on top of the spot aswell. Do I have anything to worry about and best getting it checked out or is this normal for dogs to get just like humans. Thankyou in advance.
