Roundworms and Tapeworms in a Dog's Stomach

Roundworms: Dogs pulling out white long worm-like creatures from their stomachs usually indicates an infection with roundworms, such as Toxocara canis and Toxascaris leonina. Clinical symptoms include abdominal pain, diarrhea, and vomiting. Heavy infections can cause intestinal blockage, which is life-threatening. It is recommended to seek medical attention promptly and adopt reasonable and scientific treatment. Regular deworming is also necessary to prevent severe reinfection.

Tapeworms: Tapeworms causing clinical symptoms in dogs include Dipylidium caninum and Taenia species. Tapeworms attach to the dog's intestinal wall, causing mechanical stimulation, toxin secretion, and nutrient theft. Clinical symptoms are more evident in young dogs, with larvae migration causing pneumonia (characterized by coughing and runny nose). In the adult stage, depending on the degree of infection, dogs may experience indigestion, mucus diarrhea, abdominal distension, and pain. Furthermore, tapeworms can lead to poor development, rough hair, and persistent weight loss.

For roundworms, diagnosis should be based on clinical symptoms and pathogen examination. It is important to note that worm eggs cannot be detected in feces until the worms reach the adult stage. There are many deworming drugs available, and it is recommended to use those containing milbemycin, levamisole, and other ingredients.

For tapeworms, clinical symptoms are caused by the tapeworm's suckers damaging the intestinal mucosa, stealing nutrients, secreting toxins leading to poisoning, and blocking the intestine. Mild infections usually do not present clinical symptoms, while severe infections can cause decreased appetite, vomiting, and diarrhea. Some dogs exhibit symptoms such as excessive eating, abnormal dietary preferences, weight loss, and anemia. Diagnosis should be based on clinical symptoms and fecal examination to detect proglottids or eggs. Tapeworm infections can be treated with drugs containing praziquantel, fenbendazole, and niclosamide.

Please consult a veterinarian for accurate diagnosis and treatment.
