Hi everyone..Bo had been shaking his head like crazy so I looked at his ears and the R one was red and sore. So I cleaned his ears out and gave an antibiotic. Lots of wax came out and eventually his ears returned to a nice pink color. Well now he's back to shaking his head so I just cleaned them again. His ears are still pink inside, no redness. So what could be making him shake his head this time? Also his hears had an odor before I cleaned them which I know could be a sign of an infection, but they don't look red or sore.Suggestions please, thanks!
