Which fact BEST explains how
a tiny flea could cause serious health issues to a 100 lb. dog?

Fleas can make their way into the dog's pulmonary artery and eventually their lungs.

Fleas reproduce at fast rates, so an infestation pulls needed blood away from the dog.

Fleas cause the dog to have terrible abdominal issues, keeping them from digesting food.

Fleas cause little harm to dogs as they only feed on tiny amounts of blood at a time.

Answer 1

Fleas can cause serious health issues to a 100 lb. dog by reproducing at fast rates, so an infestation pulls needed blood away from the dog. Fleas feed on the blood of their host, and a severe flea infestation can cause anemia, which is a condition where the body doesn't have enough red blood cells to carry oxygen to the tissues. If left untreated, anemia can lead to organ failure and death.
