First Welcome to YT!!
Poor Lola, I’m sorry she is sick. To me it doesn't sound like Parvo. When they have Parvo they usually have really bad bloody diarrhea, and it has a really bad smell to it. I’m talking serious smell, like something you have never smelt in your life.
I was able to research and found a couple websites for you:
Coffee ground vomiting - Wikipedia, the free encyclopedia http://pets.webmd.com/dogs/guide/_dog-vomiting http://www.justanswer.com/pet/1mpqp-...tuff-live.html
Hopefully you are able to find out what is causing this and get her treated. I will be sending good thoughts and prayers for your sweet Lola.
