Hook & Roundworms in Dogs: Causes & Treatment | Atlas Pet Hospital Parasites can quietly affect your dog’s digestive system and overall health if not managed properly. Hook and roundworms in dogs are common intestinal parasites that spread through contaminated soil, feces, or ingestion of infected material. Hookworms attach to the intestinal lining and feed on blood, while roundworms absorb nutrients from the digestive tract, potentially leading to weakness and poor condition. Puppies and outdoor dogs are often at higher risk due to increased exposure. Veterinary diagnosis typically involves fecal testing to confirm infection. Atlas Pet Hospital provides guidance on how hook and roundworms in dogs develop and how proper treatment and preventive care help maintain long-term health.
