My Chronic Pain Service Dog

I have an ongoing fantasy that my sweet little Chihuahua, Gypsy, would become a service dog. Her service, to keep me calm and happy when out and about. I would buy a dog purse to carry her in and she could just come with me everywhere I go.

*Disclaimer* Gypsy AND I are waiting in our running car while my husband pops into the store. She has never been left in a parked car alone. 

She's a great little traveler and I even think a strong argument could be made that her presence helps to release good brain chemicals, thus helping me better manage my pain levels.  However, I don't imagine she would actually do very well as a service dog because she is not good with strangers. She isn't interested in being pet or cooed over by anyone but me and my husband, and that's conditional with my husband. She's quick to bark at anyone who dares approach us. 

Really, she would only enjoy herself if she could just be there by my side with everyone else ignoring her. But come on, who could ignore this face? Those giant ears, big tear filled eyes, and cute little round head... You can see why I want to be with her all the time.

Have you ever had this fantasy with your pets?
