My dog knows how I feel and responds accordingly, she's like my sister and therapist.
I just have this way with animals, go to one friends house and their cats will hang around me, go to my other friends house and his dog adores me to death.
For example:
Jess (the dog) is barking, I go "Jess, stoppit, it's just me" she'll top sit up and start wagging her tail, no matter who else is around.
Another time, I was eating dinner at my friends place and she was laying by the door all sad-like, and mid conversation I went "and I want you to cheer up" pointing at her. Ears perked up, tongue lolled out and she started wagging her tail.
