My dog

Well, I was up all night with my dog.  I had to keep taking her out, where she was having diarrhea. Lately, she hasn't been eating as much and acting a little off.  I have a vet appt this afternoon. This really is upsetting me because, 1. I love her and don't want anything bad happening to her. I don't have children, she's what I have. 2. I'm close to losing it emotionally.  Anything could be trigger to send me over the edge.  3. I don't have the money for any large vet bills. especially right before the holidays.  Hopefully, what ever's going on is minor.

I've aways been a bit worried about her.  When I rescued her she had heart worms, so her heart isn't the best.  The vet said most likely she'll be fine after that, but still I worry.  Also, she throws up a lot.  The vet said I could spend 5 or 6 hundred dollars on tests, but they might not show much.  We concluded she just has a sensitive stomach.  I'm praying she's ok.
