I noticed this red mark about 3 weeks ago and have been keeping an eye on it as I thought it may have been a scratch and go away. It is on the lower right jaw, I have attached some pictures as is and enlarged. Speedy is a under 1 year Russian and is active, eats, drinks and sleeps and is putting on weight. It does not appear to cause any bother but would like to know if anyone has any idea as to what this is and how it can be treated?
