Hello, that looks like it could either be a local reaction to something like a bug bite. Other causes such as sterile abscess or cyst from a hair follicle or skin glands can also cause this. If it is painful or is continues to grow in the next couple of hours then I would have it evaluated by a veterinarian today. Otherwise, you can apply an ice pack or bag of frozen peas wrapped in a thin cloth over the area to see if the swelling decreases. If if doesn't or if is worse by the morning then you should have it assessed by you veterinarian tomorrow. Hope this helps and best of luck.
