Dogs are known as loyal companions. They also encourage physical activity.
But did you know they might also help detect diseases? Studies show dogs and cats can perceive changes in the human body before visible symptoms appear.
This ability comes from their incredible sense of smell and emotional connection. Dogs have up to 300 million olfactory receptors. Humans only have five million.
Their brains are largely dedicated to processing smells. This allows them to detect subtle changes in body odor. These changes could be related to various illnesses.
Dogs can also read body language and behavioral changes. They can sense when someone is stressed, anxious, or feeling unwell.
In many cases, dogs have acted strangely. This includes sniffing a specific body part, barking, or showing restlessness. This has helped owners detect medical problems early.
