I'd appreciate any help on this. Nikka our chow/pointer mix has ears that almost constantly have "gunk" (can't think of another way to describe it) in them. We've taken her to the vet numerous times and been given otimax (sp??) which clears it up for a couple of weeks then we're back to the same problem. We clean them 2X a week and try to use peroxide to loosen everything up but never seem to get everything. It's pretty much a chronic problem she's always had. I was wondering if anyone knew of anything else that might help.
