Common Internal Parasites Dogs Can Contract

Section 1: Roundworms

Roundworms are among the most common and easily transmitted parasites affecting puppies. These parasites, resembling rubber bands in color, reside in the intestines, absorbing digested nutrients. They are typically transmitted vertically from the mother to the puppy. Once infected, dogs may exhibit symptoms such as diarrhea, vomiting, and bloating. Roundworms can lead to abdominal swelling, vomiting, alternating diarrhea and constipation, and may even cause symptoms like coughing. The larvae can cause severe consequences, including liver and nervous system damage, and even blindness. It is crucial to deworm puppies as early as one month old to prevent these issues.

Section 2: Hookworms

Hookworms, also known as "duodenal worms," inhabit the duodenum. These slender parasites have hooks on their heads, which they use to attach to the intestinal walls and feed on blood. This can lead to symptoms such as bloody diarrhea, black stools, and anemia. Dogs infected with hookworms may suffer from weakness, dehydration, and anemia. For humans, hookworm infection can cause skin damage and intense itching. It is essential for bitches to be dewormed before pregnancy and during the 4th, 6th, and 8th weeks postpartum to prevent transmission to their puppies.

Section 3: Tapeworms

Tapeworms are flat, segmented parasites that attach to the intestinal walls and absorb nutrients. After each segment sheds, a new head emerges, attaching to the intestinal wall and growing a long segment behind it. If you notice moving, maggotlike worms in your dog's feces, they are tapeworms. Segments often accumulate around a dog's anus, leading to anal itching and the dog sitting on the ground to scratch. These parasites are spread by fleas, so most dogs with fleas also have tapeworms. Infection can cause abdominal pain, intestinal blockage, intussusception, or even rupture, along with symptoms like vomiting and loss of appetite. Some dogs may also exhibit extreme excitement.

The above information covers just a few of the internal parasites that can affect dogs, all of which can cause significant harm. To ensure your dog's health, it is vital to deworm your pet regularly.
