One day about 2 weeks ago we noticed a pink bump on Loki's head, it was about 1/4 inch wide, and about 3/16 tall. As it healed, and went down, it is now white, but would swell up again for the first week. There is no hair in it now. We thought at first it may have been a bee sting or something.
Now he has 2 small bald spots, both >1/4 inch wide on the top of his head, about 1 inch apart. Only really noticeable if you look from behind and know they are there really. I have heard these 'hot spots' mentioned but have no idea what they are.
Any ideas what went on here?
