What is a common sign of an ill animal?

A swollen stomach can be a significant sign of illness in an animal. This condition may indicate a serious problem such as gastrointestinal distension, fluid accumulation, or an obstruction. When an animal is ill, changes in appetite, behavior, and physical condition often manifest, and a swollen abdomen is particularly concerning. It can be associated with various health issues ranging from infections and organ dysfunction to more severe conditions like bloat or tumors.

In contrast, a vigorous appetite, active behavior, and normal breathing typically signify good health or normal physiological function. An increase in appetite might even suggest the opposite of illness, while active behavior and normal breathing are indicators of a stable and healthy state. Thus, recognizing a swollen abdomen can prompt further investigation and is crucial for diagnosing underlying health issues in an animal.
