Hi.

I have a male 8/9 year old lop mix rabbit named Mocha.  I adopted him at 2/3 years old and since then he has suffered from ear infections 2-4 times a year.

typically we do a course of antibiotics and he’s good to go after 14-30 days.

currently he has had an ear infection since June. We started with packing his ear an Otic pack for two weeks and then again for two weeks Then we moved onto baytril then we did a culture that said baytril should’ve worked, but since it didn’t we used Cipro as it also tested as effective.  We just refilled the cipro script after our 30 day course and are currently on day 40.  There are days where I do think it looks better and then the next day there will be large thick gobs of pus in his ear again. The pus is sometimes bloody, but has lost its yellow color and is just white now.
Our second opinion vet told us it is hard to see deep into his canal, but that it is possible she saw a tumor.  She stated it isn’t something I should be worried about though.

I just feel like after 40 days of cipro we should be further along. I’m staring to get very concerned.

im just curious if anyone has any next steps, or ideas for us.  He is eating well and pooping normal.  He lives with another male rabbit Latte who has not suffered any ear infections.  I clean their space multiple times a week.

please any info is appreciated.
