Thanks for writing in,
I'm happy that your girl is eating fine and very energetic. She could have just gotten into something that caused alittle upset belly. Because she is doing great right now, all I may recommend you do is put alittle bit of nonflavored plain yogur on her food when she eats. This will help replace the "good bacteria" that she is losing with the soft stool. Do not give her any more raw egg as this contains salmonellla and could cause worsening diarrhea.
IF at any point her energy level really goes down, she isn't wanting to eat, diarrhea continues, and vomiting occurs, then you will want to be sure to get her to the vet asap as she can become dehydrated very quickly and will want to rule out the possibility of parvo. Take care and congrats on the new pup!
