Cocoa looks like she has a severe respiratory infection as well and would benefit from a prolonged course of antibiotics for her severe nasal discharge. Assuming that the dewormer given was appropriate for the types of worms/intestinal parasites that she has, she would typically need to be dewormed again in 2 weeks and have a reaper exam to confirm that she is negative for intestinal parasites in approximately 3 weeks. Pyrantel is effective against roundworms, hookworms and whipworms. For Tapeworms, she would need praziquantel or a broad spectrum dewormer such as Drontal Plus. For Giardia she would need metronidazole and Panacur and for coccidia, Albon is the medication of choice. All of these parasites are zoonotic and contagious to people and other dogs as well. Diligent handwashing after handling is recommended, as is diligent environmental cleanup as she can easily become re-infected if she walks back over stool left in the backyard and licks her paws. Good luck and best wishes for a speedy recovery!
