Does anyone know why my cocker spaniel's ears always smell like sweaty socks that have been left in the bottom of the washing basket for too long? He is regularly groomed / bathed and according to the groomer she doesn't think there is any ear problem / infection. She just said to keep the ear hair shorter. Is there anything we can do? I can't believe that ears can cause so much of a smell. We get a waft every time he walks past and it's horrible! Makes the room smell too.
