Hello,
I have a lovely little mix terrier dog Saoirse, she has a black mole like spot on her belly approximately 1/4 -1/2 cm in diameter, not fully round that has a very white 2-3 mm boarder around it. The hair appears intact and it does not irritate her. Does this sound like something to be concerned about? Does anyone know what this might be and what I can do about it?

Thanks so much!
