My 1.5 year old puppy always looks so depressed in the photos that my parents send me. I've been gone 5 months (but visiting next month). I'm sure I'm not imagining it. I know when he's happy, he looks like he's smiling, open mouth, sparkly eyes, tongue out, huge grin. In the photos, his mouth is an upside down U.
Does he miss me? Or am I anthropomorphising?
