I know this is common behavior in the animal kingdom, but we just started noticing it in our corgis. when we first got kai, the inside of her ears would be filthy with that dark ear wax substance. but keahi has since picked up the habit of licking them clean - kai will just sit there while keahi gives her the ultimate wet willy. not that we're complaining. but keahi is now starting to "clean" kai's "poop chute" area after she goes no. 2.
is that also part of normal grooming behavior? does anyone else have dogs that groom each other in peculiar ways?
