Our white columbian has a bump...hard to see in the photos(camera died, so I'm waiting for a recharge). She has had it but it doesn't seem to bother her. It is pinker/reddish in color and it's on both sides of her face above her eye.
and this applies to all animals and humans...every time I find a bump, I feel on the opposite side for another one. If I find one, everything's fine So...whatever they are...she's probably supposed to have them.
