Unbelievable! According to a random dog body-language interpretation site I found via Google, Atticus is showing some unmistakable signs of stress! The ears back? The tongue out? Our site tells us that's a dog who is "stressed" likely by a situation of "frustration or fear." The standard explanation for this photo, that Atticus was "tired" from "playing" with Jake was not one of the options the website listed! In fact, the site didn't mention Jake at all.
Is this exhaustion physical or emotional? Only time will tell. But I think we all might want to consider the possibility that Jake is giving most of his attention to the newest member of the family, ignoring those who have been around a little longer.
Possibly most disturbing of all, I have uncovered the dastardly truth that even though I know for a fact that Jake told Atticus he couldn't use the internet until he was older, he has already let younger brother Boo set up his own MySpace page. The inequality here is just shocking.
(P.S. Inequality aside, you should add Boo to your MySpace friendlist since his profile was created in affiliation with this blog.)
