Have you ever noticed your dog behaving differently when you aren’t feeling well? Perhaps they become more attentive, sticking to your side like a furry shadow. Or maybe they demonstrate unusual calmness, as if understanding that you need peace and quiet. These behaviors may not be coincidences. It’s believed that dogs can indeed sense when their human is sick. This article will delve into this fascinating topic, exploring how dogs might be able to detect illness in their owners, the science behind it, and what specific actions you can watch for in your dog that might indicate they realize you’re not at your best.

Key Takeaways
- Dogs have an extraordinary sense of smell that can detect changes in their human’s body chemistry.
- Behavioral changes in dogs can be indicators of their awareness of your illness.
- Scientific research supports the notion that dogs can sense illness in humans.
Dogs’ Incredible Sense of Smell
To understand how a dog could sense an illness in their human, it helps to first understand the remarkable power of a dog’s nose. Dogs possess up to 300 million olfactory receptors in their noses, compared to about six million in humans. Moreover, the part of a dog’s brain that is dedicated to analyzing smells is, proportionally speaking, 40 times greater than ours. This makes a dog’s sense of smell between 1,000 to 10,000,000 times more sensitive than that of a human, according to Nova.
Dogs Detecting Specific Illnesses
When you are ill, your body chemistry changes, and these changes can produce different smells. A dog’s powerful nose can pick up these subtle changes. Various studies have shown that dogs can be trained to identify the scent of certain diseases.
For instance, certain dogs can detect specific types of cancer. OneTopDog has a couple of articles related to this topic. Dogs have been successfully trained to sniff out skin, bladder, and lung cancers, and research is ongoing into their ability to detect other types of cancers.
It’s not just cancer that dogs can sniff out. They can also detect changes in blood sugar levels, which is why some dogs are trained as diabetic alert dogs. They can even sense the onset of a seizure in epileptic individuals.
Behavioral Changes in Dogs When You’re Sick
Your dog’s behavior may change if they sense you are sick. They might become more protective, stay close to you, or show signs of distress. They could also become quieter, more subdued, or even refuse to leave your side. Each dog will respond differently, but these changes in behavior can be indicative of their awareness of your illness.
The Science Behind Dogs Sensing Illness
The science behind dogs’ ability to sense sickness is primarily related to their sense of smell, as mentioned earlier. Dogs’ noses function quite differently from ours. When we inhale, we smell and breathe through the same airways within our nose. In contrast, dogs have a fold of tissue inside their nostrils, so when they inhale, they can separate smelling and breathing. This allows them to identify scents more precisely.
A study published in the journal Gut found that a Labrador Retriever was trained to detect colorectal cancer with high accuracy by sniffing the exhalations of patients. This study, among others, suggests that dogs can detect volatile organic compounds (VOCs) that are released by cancers.
Apart from their remarkable olfactory abilities, dogs are also very attuned to their owners’ behavior. They notice when your routine changes or if you’re not as active as usual. This attentive nature, combined with their keen sense of smell, makes them excellent at detecting illness.
Frequently Asked Questions
1. Can my dog tell if I’m sick if I don’t show symptoms?
While research suggests that dogs can sense certain illnesses even before symptoms appear, it’s not guaranteed that your dog will be able to do so.
2. Can dogs sense mental illnesses?
Dogs seem to be able to pick up on their owners’ emotional states and may be able to sense conditions like depression and anxiety.
3. How can I tell if my dog is trying to comfort me when I’m sick?
If your dog is sticking close to you, showing you extra affection, or acting more subdued than usual, they might be trying to comfort you.
4. Can dogs be trained to detect diseases?
Yes, dogs can be trained to detect certain diseases. For example, diabetic alert dogs are trained to detect changes in blood sugar levels.
In conclusion, while not all dogs will react the same way, it’s clear that many dogs are capable of sensing when their human is sick. Whether through changes in smell or behavior, our canine companions often show a level of sensitivity and empathy that is truly remarkable. This extraordinary talent further solidifies the special bond between dogs and humans, a bond that never ceases to amaze and warm our hearts.
