Which of the following is a characteristic sign of Naalehu disease?

Naalehu disease, primarily affecting dogs, is characterized by significant cachexia, weakness, and wasting. This condition results in a noticeable loss of body weight and muscle mass, which can be attributed to several factors, including underlying illnesses and chronic infections. In cases of Naalehu disease, as the body struggles to combat the disease, it often leads to a decrease in overall physical condition, presenting itself as weakness or lethargy.

Symptoms like increased appetite, bright red eyes, or rapid growth do not align with the typical presentation of Naalehu disease. In fact, a dog suffering from this condition may have a reduced appetite as the disease progresses and may appear less energetic. Understanding these signs is crucial for early diagnosis and intervention, making the recognition of cachexia and associated symptoms vital in veterinary practice.
