Your girl who was lethargic, losing weight, not drinking water, pale gums and eyes on April 15 was spayed in the last couple of days? How is she doing? I hope this is a good sign that she recovered quickly.

If your parents did not want to bring her to the vet, I have to question why/how you would bring another dog into your life.
