Sasha: Therapy (for us) Needed

Sasha has been a good little therapy dog for us.  She has been my little mainstay friend for the last few months but she also has been helpful to both of us the whole time we have had her. She also sometimes makes us wonder if we need therapy:).
Last night as we heard ourselves talking to her, we had to wonder. I heard myself saying "Good girl. Here's your treat.  Now you can go to bed with Daddy or stay up with Mommy." What is that about!?
We hear ourselves saying other things to her like "You little .. (nothing too bad)" when she is in what we consider her bipolar mood. We do yell at her when she runs from window to back window barking ferociously at every dog, family or diesel powered truck that dares to pass by. She rests most of the day but comes alive - sometimes with a vengeance - with energy to play and wants constant attention in the evening. We wonder what people might think if they were passing by on the sidewalk or worse yet, could see us and hear us on video talking baby talk to her.
We talk to her about who knows what, each of us having little monologues with her. She cuddles up to us, sleeping between us (which we used to say we would never do) and we think of her as a little person around here. She is cute with her little routines - runs (treat expected of course) to the kennel when Tom asks her to so he can get me and the wheelchair out the door without her escaping.  Then, when  Tom goes in to release her, she perfectly poses herself on top of the middle pillow looking like the cutest little dog in the center of our front window.  It makes us occasionally think of the song "How much is that doggy in the window?".  Like I said, she is therapeutic to us and we have reason to feel there may be a gap of needed therapy which we have so far missed.  Somehow, I feel sure some of you pet lovers will understand.  I sure hope so.
