One of my rabbits looks somewhat similar and I believe it’s from bar chewing. If the rabbit was kept in a hutch for most of its life, it could be from constantly trying to get out?

If it is from bar chewing, it should get better in a better environment.

Notably my same rabbit also had syphilis. Syphilis can come from birth from an infected mother, so even with no contact, it could still contract it. That being said, my rabbit was treated and still sort of looks like that so I don’t think its syphilis related.

Upon a closer look I actually think I see a bit of yellow scabbing at the bottom? Unsure if that’s wet or scab, but if it is, that is more on track for syphilis.

My first thought was syphilis as well. Other possibilities could be ringworm, or sometimes a respiratory infection will lead to fur loss around the nose and mouth due to constant wetness. But without any respiratory symptoms I think ringworm or syphilis are more likely.

The yellow crusties seem syphilis-ish to me, but it could be ringworm too. As the others said, rabbits can have it since birth, only to have it surface later in life.

Hi @Rosie_M did you end up finding a solution? My bunny currently has a similar condition and is being treated with Penicillin but it doesn’t seem to be working. I read this forum from a while back and am going to see if getting organic food improves anything – https://binkybunny.com/forums/topic/lip-scabs/

Let me know if you’ve had any luck

Thanks!
