Your vet already did a fecal check and found nothing? Coccidia usually shows up, giardia on the other hand is harder to diagnose. Did you do a complete blood check? If something is seriously wrong usually something will be off to give the vet a direction on where to start looking. When you say she gets sick at night do you mean she is vomiting a yellow frothy vomiting or actually vomiting digested food or having diarrhea?
If it is just the frothy yellow vomit then most likely it is due to having unabsorbed acid in the stomach and can usually be fixed by feeding a late night snack and early breakfast. They vomit the acid to get it out of their stomach, but it is harmful if done a lot because it can erode the lining of the stomach and esophagus. She may even need to be put on Pepcid if the change in feeding schedule doesn't help.
Benebac (beneficial bacteria sold in a tube for about $6.00 - more concentrated than yogurt and no risk of lactose causing diarrhea) can be of a lot of help with any digestive system disorder.
Some things are just hard to get to the bottom of since dogs can't talk, but some vets are so busy they just don't have the time to listen to find out what is wrong - if you feel this is the case than time to get a new vet. If it's a diagnosis without any real "traditional" help, start researching and looking into herbal remedy preparations. |
