Why does my dog still have worms & bloody diarrhea after deworming?

Updated On September 23rd, 2025

Pet's info: Dog | German Shepherd | Female | 2 months and 27 days old | 10 lbs

My dog is very sick. I have wormed her and she is still throwing up worms and having bloody diarrhea and she won’t move a lot we’ve been putting fluids down her. She is throwing up foam. She wines and has lost a lot of weight idk If she is ate up with worms or has Parvo. We gave her a Parvo shot and the next day she was sick it seems to be because of worms though. They women I got her from said She wormed her 2 then I wormed her a 3rd so why does she still have worms is this fatal?

The deworming product you are using is probably not good enough, you must take Sophie to the vet urgently in order to get her dewormed with a stronger/better product Urgently as this can indeed be fatal if left untreated.
