Here are a few interesting and unusual facts about dogs:
Dogs can get jealous. A study published in the journal PLOS ONE found that dogs show signs of jealousy when their owners show affection to a stuffed animal or another dog.
Dogs can recognize their own reflection in a mirror. This rare trait is only found in a few species, including humans, apes, and dolphins.
Dogs can sense earthquakes. Some dogs have been known to bark or become agitated before an earthquake occurs, possibly due to their ability to sense changes in air pressure or vibrations in the ground.
Dogs can be left- or right-pawed. Just like humans, some dogs show a preference for using one paw over the other.
Dogs can detect certain types of cancer in humans. Some studies have shown that dogs can detect the presence of cancerous cells in humans with a high degree of accuracy. They may do this by sniffing out volatile organic compounds (VOCs) emitted by cancerous cells.
Dogs can develop facial expressions specifically for their owners. A study published in the journal Animal Cognition found that dogs are more likely to make a specific facial expression (such as raised eyebrows or a “puppy dog” look) when they are looking at their owner compared to a stranger. This suggests that dogs are able to recognize and respond to their owner’s emotional state.
Dogs can get “seasonal” allergies, just like humans. Some dogs may develop allergies to pollen, grass, or other environmental triggers, which can cause them to scratch, lick, or chew excessively.
Dogs can get sunburned. Dogs with thin or light-colored fur are more prone to sunburn, especially on their noses and ears. It is important to use pet-safe sunscreen on your dog if they will be spending a lot of time outside in the sun.
Dogs can get “doggy” acne. Just like humans, dogs can develop acne on their faces and neck. It is most common in puppies and younger dogs, and it can be caused by a variety of factors, including hormonal imbalances, allergies, or sensitivity to certain types of food or grooming products.
Dogs can dream. Dogs have the same brain waves as humans during the REM (rapid eye movement) stage of sleep, which is when most dreaming occurs. It is not clear what dogs dream about, but it is likely that they have similar dreams to humans, such as chasing a ball or running through a field.
Dogs can have “fake” pregnancies. Some female dogs will show symptoms of pregnancy, such as lactating and producing milk, even if they have not been bred. This is called “pseudopregnancy” and it is caused by hormonal changes in the body.
Dogs can learn to detect low blood sugar in humans with diabetes. Some dogs have been trained to alert their owners when their blood sugar levels are too low, which can be a lifesaving ability for people with diabetes.
Dogs can develop a “sixth sense” for detecting when their owner is coming home. Some dogs seem to be able to predict when their owner is about to arrive, even if the owner is not following their usual routine. This ability is thought to be related to a dog’s keen sense of smell and ability to detect subtle changes in its environment.
Dogs can have “phobias” just like humans. Some dogs may develop a fear or phobia of certain objects, situations, or events, such as loud noises, storms, or being left alone. These phobias can be treated with behavior modification and desensitization techniques.
Dogs can be trained to detect illegal drugs, explosives, and even cancer. Some dogs are trained to use their highly sensitive sense of smell to detect illegal drugs, explosives, and other substances. They are often used by law enforcement agencies and military organizations. There is also ongoing research into the use of dogs to detect cancer in humans by sniffing out volatile organic compounds (VOCs) that are emitted by cancerous cells.
Dogs can get “jet lag” just like humans. When dogs travel long distances, they may experience changes in their sleep patterns, appetite, and behavior that are similar to what humans experience when they have jet lag.
Dogs can develop a “green muzzle” from eating grass. This is a common behavior in dogs, and it is thought to be related to their natural instinct to forage for food. Some veterinarians believe that dogs may eat grass to help them vomit when they are feeling sick, while others think that it may be a way for dogs to get extra fiber in their diet.
