Hi guys, i noticed that my dog scratches her ear often. I checked them and found some dirt. Although the dirt i saw is not that bad, but i'm still worried thinking that it can be an issue in the future. I tried several times cleaning only the external part but my dog just don't like it. I just use clean clothes to wipe it but shes not comfortable at all. I'm wondering is there a way or a technique on how i can clean my dog's ear?
