Parasites in Dogs

Dogs can be infested with two types of parasites:

1. Internal parasites:

Endoparasites

Parasites that are located primarily at the level of the digestive tract. These parasites typically affect the esophagus, stomach and intestines, with area-specific parasites of the digestive tract, there are several genera and species, such as tapeworms and roundworms, commonly known as the "worms."
Some of the symptoms that the dog has internal parasites are: vomiting, diarrhea (which we are often visible parasites), weight loss (eg in the case of dogs we can see some swelling in the abdominal area and anemia).
These parasites can be transmitted by eating their eggs (found in water, food), transmitted by the mother dog or through intermediate hosts such as fleas.

2. External parasites

Ectoparasites

Parasites generally animals that feed on the blood of the dog, such as fleas, ticks, mites and lice.
Some of the symptoms that the dog has external parasites are: itching, allergic reaction to the bites, hair loss, intense itching and sores when it itches too. Apart from the discomfort that the parasites causing the animal, can transmit many diseases.
