My last dog a black lab, used to lick my face, obviously upset and trying to make it better....
But Mateo is different: when during those odd times I find myself in a mini breakdown mode, he will come over to where I am sitting, crumpled on the floor, and sit as close as he possibly can, sticking his chest out, with his chin in the air. I usually hold onto him while sobbing. After a few minutes, when I try to move away, he pushes himself closer, almost as if to say, "wait- I'm still here, and you're still upset...I can help. That's what I am here for...hold on to me."
Maybe I'm projecting, but it is obvious that he wants to offer support...in the only way he knows how. And it's awesome.
