I have a 2 yr. old female Great Dane, she gets sist/wort like bumps on the bottom of her chin, and muzzle. When she plays and bumps her chin, they bleed. In appearance they just look like the skin has been scraped. They then scab over, but bleed again when the scab scrapes off. Is this something that is common to Great Danes? Is there anything we can do to prevent these bumps?
Sounds like she has acne. Try oxy10 with benzoil peroxide. Leave it on for 10 minutes, then rinse. vetcare
