Gunny (the GSD) does that to Yogi all the time! Ugh! Yogi doesn't seem to mind it though. Yogi does get really mad when Gunny pulls on them too hard! When I clean Yogi's ears out Gunny comes over and tries to do the other ear and then when I am done he goes into the clean ear and cleans that one too! I always wondered if it was a submissive type thing? Gunny also licks the side of Yogi's mouth and face too. I don't really like the ear thing but as long as Yogi doesn't mind I am inclined to let it go.
