Rabbit Has White Nasal Discharge

by Hope
(USA)

I have a 10 month old Californian doe who has had a white nasal discharge (like milk) for the last 4 months. She is eating and seems normal otherwise. I have her with my other rabbits, but in an end cage, surrounded by cardboard, and I care for her last.

I give her 1/4 cc TwinPen sub-q, every other day for a week. This seems to help. But a week or two later, the sneezing and discharge is back.

This last time, I gave her 1/2 cc TwinPen every other day for 2 weeks. Just one week after the treatment, she is sneezing and has a white discharge again.

Any suggestions?
Thank you,
Hope
