I gave my 4 months old puppy an anthelmintic for deworming about 5 days ago. However today, my dog is sick. Since last night she started not to eat. Early morning today, she started vomiting and I saw tapeworms on her vomit or poop. Her poop isn't normal and looks like vomit too. I'm worried she won't survive so I'm gonna have to take her to the vet. What I wanted to know is if this is normal when deworming? She hasn't eaten for more than 24 hours so I started feeding her with broth (chicken, carrots, garlic). I also make sure that she stays hydrated by giving her water every 3 hours. Am I doing it right? I'm a real amateur with dogs. I used to have one but that was when I was just a kid and that was more than a decade ago. Any advice?
