After updating my vet they recommended another exam to try and figure out what else might be going on since the panacur wasn't working for her. They were very booked up, so the soonest I was able to take her there was yesterday.
She did well on her physical exam and instead of any further testing we decided to first try a new medication. My vet's theory is that the pinworms showing up in her fecal may actually be rodent pinworms from her food and are not what's affecting her, so the idea is that the new medication might be able to target something bacterial or parasitic that is not being reported on the standard fecal and could be the actual cause of her symptoms. The med is metronidazole/flagyl, and if this treatment doesn't work either our next step is a more in-depth fecal (I think he called it a fecal smear) that should hopefully reveal more about what's going on in her GI tract.
Good choice- I've used Flagyl in the past, it's pretty safe & effective- I sure hope this takes care of her lingering issue.
