Hello and thank you for reaching out to Petco Pet Education Center, formerly Petcoach. It sounds like Buffy is very sick, since she can't keep down water and is also having diarrhea, and is unwilling to move around. I highly recommend that Buffy be seen by a veterinarian. As a 15 year old dog, I am worried about a possible cancerous cause of her clinical signs. Diagnostics such as bloodwork and even an abdominal ultrasound would likely be necessary to determine the underlying cause. At the very least, your veterinarian can discuss possible palliative treatment options to try to get Buffy feeling comfortable again. It is also not wrong to consider the option of humane euthanasia, to help eliminate Buffy from suffering. I know this is a difficult choice, but from what you are describing I don't believe it would be wrong. I hope this is helpful.
