What other signs might indicate a heavy roundworm infection in puppies besides a bloated abdomen?

Heavy roundworm infections in puppies can manifest through a variety of clinical signs. A bloated abdomen is a common external indicator, but additional signs provide further evidence of such an infection. Diarrhea can occur as the presence of numerous worms interferes with the puppy's ability to absorb nutrients, leading to gastrointestinal upset. Coughing is also significant as larvae can migrate through the lungs before being swallowed back into the intestine, which can lead to respiratory symptoms.

Other choices may describe symptoms associated with different health issues or parasites, but they are not directly linked to roundworm infections. For example, seizures and disorientation typically indicate neurological issues rather than parasitic infections. Excessive barking and aggression are behavioral concerns that do not relate to physiological symptoms of roundworm infection. Skin infections and irritations might suggest other dermatological conditions or infections, but they are not primary signs of roundworm presence.
