Runs but getting better

So today Ruby still has the runs.. I am thinking its from too much organ meats. So i picked up some flagyl to help with the runs for the poor Weeble.. We are on a chicken diet for the next 3 weeks to see if it helps lessen her itching/scratching/chewing. so far her itching/scratching/chewing has lessened up a little bit, but she also got a bath with Dermal Pet Soothe Allergy Relief shampoo, so it could be a combo of both. She gets nothing but chicken for the next 3 weeks to rule out allergies to chicken, then we move on to turkey, and try that for 3 weeks. After that, beef, etc... Her only allergy reading that came up strong was to storage mites at 126, but just to be sure we are ruling out food as well..
