What Is It??

Anorexia can range from partial anorexia, where the pet eats less than usual, to complete anorexia, where the pet refuses food altogether.

Causes?

Anorexia in dogs can stem from various causes, including medical issues like pain, infections, organ dysfunction, or gastrointestinal disorders. Behavioral factors such as stress, anxiety, or changes in routine may also contribute, as can serious illnesses like cancer, immune disorders, or neurological conditions. Additionally, certain medications can cause nausea or suppress appetite as a side effect.

Additional info?

Anorexia is a serious clinical sign that should not be ignored, as it often signals an underlying health issue. If your dog experiences a prolonged or sudden loss of appetite, consult a veterinarian promptly to determine the cause and begin appropriate treatment.
