When dogs are severely infected with tapeworms, they may have abnormal appetite, vomiting, chronic enteritis, anemia, weight loss, irritability or depression, and some may suffer from convulsions or paralysis of the limbs. When the worms form into clumps, they can block the intestines, leading to acute abdominal diseases such as intestinal obstruction, intussusception, volvulus, and intestinal rupture. The anal opening contains tapeworm gestational segments that have not yet landed, and the feces contains short tapeworm segments.
