My bassett has been sick for about a week. Her symptoms started out as listlessness, loss of appetite, and then progressed to bloody diaharrea and shaking. She drinks water and pees all the time. I have been giving her burger and rice to eat which she will eat. Her stools then turned tarry and then today they seemed to be kind of green. She isn't herself and still shakes and wont leave my side. What could she have?
