You aren't suppose to clean it ears and if you want to clean its ears go to the vet
If you want to clean their ears yourself then get advice from a vet first. I did and now I clean them once a week
It is very easy to clean the Ears of an English Bulldog. You can use a cloth soaked in warm water and remove any debris and dirt. A cotton Q-tip can also be used but only at the edge of the ear canal. For odor problem take him to the vet it might be serious.
