LONG Update on Lola..bad 2 days and I found her breeder!

If you read my last few posts then you know that we found out Lola had a cough on Tuesday and I was trying to track her breeder down to attempt to figure out why she's so sick all the time.
So here's the update..... Lola has been coughing pretty bad since Tuesday and she has a very runny nose.  She's on an antibiotic and robitussin.  I don't think she's slept through the night since..and neither have we.  Yesterday morning she started having loose stool and I noticed a little blood in it.  I thought the blood might be because she had the runs.  She only ate one cup of food yesterday by the time I went work at 1pm, my mother called me at 5pm to tell me that Lola had gone in her kennel which she never does and it was very bloody.  I got home at 9pm and from 9pm until 5am this morning she was outside going the bathroom every 15 or 30 minutes!  And it was pure blood coming out of her.  I had to keep wiping her butt because there was blood all over it.  I felt so bad, she was whining all night and neither of us slept more than 2 hours.  I tried putting her in her kennel, but 15 minutes after I went upstairs I could hear her crying and I ran downstairs too late, she had gone in her kennel.  So I cleaned up and took her upstairs with me, but every 15 minutes we were both running downstairs and out the door.  So I ended up on the couch and left the backdoor ajar a little so she could run in and out...yard is small and completley fenced in.  By 6am I think we both passed out until 7:30am, then I had to get up for work.  I called the vet right when they opened and made an appointment for 4:30pm (all the had open).  Went to work until 3:30pm, then off to the vet.  They took a stool sample to rule out parasites.  They think it's either that or a reaction to her meds for her cough.  They put her on Metronidazole for her stool problems.  So right now I have to give her that, her cough meds, the Robitussin and Pepcid AC if I want to.  They want her on a bland diet of chicken and rice for 2 days.  They'll call with the results of the stool sample on Monday.  I'm just so upset and feel so bad for her,  I feel like she's sick every other week and it makes me feel like a very bad mom.  So, since she is sick a lot I decided that I wanted to track down her breeder and find out if the parents or rest of the litter had any issues.
My boyfriend gave me her number because he was the one that found her on the internet and bought Lola for my birthday.  She was very nice, but really had no information for me.  She said that she owned the mother for 6 years and never had any health issues with her (she recently got loose from the house and hit by a car and has passed on).  She doesn't own the male, but knows the guy who does and said he has had no problems that she knows of.  She kept 2 puppies from Lola's litter and said they are both healty and has had no problems....one white male and a briddle female.  She gave 2 other puppies away besides Lola one to Florida and one to Michigan, so she is going to call them to find out how those puppies are and then give me an update.  I asked about health testing prior to breeding and all she kept saying were both parents were/are healthy.  Red Flag.....I don't think any health tests were done.  All in all, that didn't help me.  She was very nice though, and seemed very concerned for Lola and wants me to keep her updated.  
So that's the story.  Sorry so long, I had to share & vent with people who would understand.  Right now Lola's passed out...let's hope we both get some sleep tonight!  Poor thing has snots running down her nose and blood running down her butt.....but she's still beaning and running around with toys in her mouth just wanting to play!  God bless her!
Thanks for listening / reading!  I'll post an update when the results come in.
