Which of the following symptoms is associated with CHF?

Congestive Heart Failure (CHF) in animals is characterized by a variety of symptoms that reflect the heart's reduced ability to pump blood effectively. Fatigue is a common symptom associated with CHF, as the condition causes inadequate blood flow to the muscles and organs, leading to decreased energy levels and overall weakness. Animals may exhibit signs of lethargy, difficulty in exercising, or a general lack of interest in activities they once enjoyed due to this lack of energy.

In contrast, symptoms like increased appetite or hypotension do not align with the typical presentation of CHF. In fact, an animal suffering from CHF usually experiences decreased appetite due to a combination of factors, including nausea from fluid build-up or reduced blood flow to the digestive organs. While hypotension can occur in various cardiovascular conditions, CHF often leads to hypertension due to fluid retention. Additionally, a bright red blood cell count, which might indicate polycythemia or another issue, is not directly related to the symptoms of CHF, where fluid overload and heart dysfunction are more prominent.
