Arrythmia. Fluid in the lungs. Vomiting blood. Signs of liver failure.
To figure out what's causing all this, Allegra needs EKGs, ultrasounds, X-rays and a multitude of other diagnostic tests. Starting at around $1K, just for diagnostics, not treatment. The likely suspect is, it figures, cancer.
Now I'm faced with the decision of whether to continue what will be a very costly process that has no guarantee of Allegra's survival.
Or I can have her put down.
