Giardia is sometimes hard to get rid of. If your vet is actually seeing the cysts in her stools she probably has quite a few. At least you know that is what she has for sure. Many times the cysts don't even show up in a fecal exam. You actually never get rid of all of the cysts and they can become reactivated in times of stress. I would just continue with the flagyl - metronidazole. |
