What could changes in a dog's appetite indicate?

Changes in a dog's appetite can be significant indicators of underlying health issues. When a dog experiences increased or decreased appetite, it may be a sign of dental problems, such as pain or discomfort while eating, or systemic illnesses, which could range from infections to chronic conditions. For instance, conditions like kidney disease, diabetes, or cancer often impact a dog's desire to eat or their ability to do so comfortably.

Addressing dental issues, for example, may help restore a dog's appetite, as pain from periodontal disease can lead them to avoid food. Likewise, systemic illnesses may suppress appetite due to factors like nausea, pain, or metabolic imbalances. Thus, observing changes in appetite is critical for identifying potential health concerns that require veterinary attention.

In contrast, the other options relate more positively to health statuses. Increased energy levels and improving digestive health are typically reflected in a stable or improved appetite, while normal metabolic rates suggest that the dog's body functions properly without distress signals like changes in hunger.
