What are the symptoms of a dog infected with echinococcosis?

Echinococcosis, also known as hydatid disease, is a parasitic infection caused by tapeworms of the genus Echinococcus. Dogs, as intermediate hosts, can contract this disease, which can lead to severe health issues. Recognizing the symptoms of echinococcosis in dogs is crucial for timely treatment and prevention of further complications.

Visible Symptoms

Dogs infected with echinococcosis may exhibit a variety of symptoms. One of the most common signs is a persistent cough, which can be dry or productive, depending on the location and size of the cysts. As the disease progresses, the dog may also experience difficulty breathing due to the pressure exerted by the cysts on the lungs. In some cases, the dog might develop a hacking cough that leads to the expectoration of blood.

Another noticeable symptom is abdominal swelling. This occurs as the cysts grow within the abdomen, causing the area to become distended. The dog may also show signs of abdominal pain, which can lead to a decrease in appetite and subsequent weight loss. Vomiting and diarrhea can also occur, further contributing to the dog's decline in health.

Subtle Symptoms

Some symptoms of echinococcosis in dogs are more subtle and may go unnoticed initially. These include lethargy and a general lack of energy. The dog may become less interested in activities it once enjoyed and may seem to tire more easily. owners might also notice a change in the dog's coat, which may become dull and lackluster.

In cases where the liver is affected, the dog may show signs of jaundice, such as yellowing of the eyes and skin. This is due to the liver's impaired ability to process bilirubin. Additionally, the dog may develop anemia, which can cause pale gums and weakness.
