Bleeding Gums Picture I Have A Boxer And His Lips Bleed Occasionally?

I have a boxer and his lips bleed occasionally? - bleeding gums picture

I did bleed a boxer for three years and outside of the lips, because it can be scratched and bit him. I'm trying to find out what may be causing the problem, but nothing has changed, or made the arrest. Not bad, just a few drops from time to time. It is the picture of health and has nothing else wrong with him as his lips.

This is not your gums. Is your mouth.

Has anyone else this problem or suggestions.
