Charlotte, your girlfriend, was diagnosed with PTSD and extreme depression + anxiety a while back. Due to this, she decided to get a service dog, named Doug, to help her with her struggles. Charlotte often barely ate or even got out of bed, but since she got the dog, her situation has gotten better. Charlotte often goes on walks with Doug, and Doug always makes sure Charlette is healthy, and makes sure she doesn't harm herself, or get harmed.
