Dogs are smart

This is my Gracie
I really believe that dogs have a sixth sense for picking up on their owners emotions. I was feeling pretty low today and i sat down next to my Gracie (border collie cross beagle) and she just lay down against me and put her head on my leg. Now this may seem like normal dog behavior but not for Gracie, she is usually really hyper and will get distracted by anything and just tries to lick your hands as you pat her. However she was quite happy to close her eyes and just sit with me.
It is not the first time that she has done this, i used to sit with her all the time when i had first moved to Adelaide and she would sit quietly and comfort me.
I also know of a 21yr old girl, Hannah who has multiply disabilities and spends her life in a wheelchair, she can't speak or do anything for herself. For her birthday she was given a puppy. The dog, Tess, runs around all hyperactive unless she is with Hannah in which case she snuggles up and sleeps in her arms.
I know that we humans consider ourselves smarter than dogs but i think they are a lot smarter than we give them credit for.

Here is another pic of her

And this is Gracie and Truffles (my other dog)
