both my dogs know when I am upset or aren't feeling well.
When I am sick Pixie will crawl under my chin and keep licking my face sometimes I am like enough already I am going to live. I guess if I didn't have all that love Id be lost

Daisy just tends to stay by my side and when she knows I am sad she wil kiss me and sigh a lot. 
I too try not to get sad or cry over things bc they are so tuned into it.
gotta love the doggie unconditional love
