Achilles aka ChiliDog is an Australian Cattle dog mix. I’ve owned him for just over seven years and guess his age to be ten or eleven. In two ways he is atypical of the breed because he has never met a human he disliked, and also because he is not driven to do a job, though I suppose liking humans is a job. Often when he is at rest or relaxed his tongue hangs out like this. I have no idea why and he certainly isn’t letting me in on his reason.
