Good Morning and welcome to Just answer. I am Dr. Loretta, a licensed veterinarian and I am happy to answer your question.
It is not unusual for Giardia to be dificult to get rid of. For this reason, we will retest after a treatment and if your girl still has Giardia, they will treat again. It may take a few treatments to get rid of this terrible parasite. This LINK will help explain in more detail....don't worry....it may take a few times but you will get rid of this.
Does that make sense to you?
Please let me know if you have ANY other questions. My goal is to give you 100% satisfaction and if you are not yet satisfied, please Reply so I can clarify for you
