Over the past few years, researchers have studied more than 36 different types of dogs. It is interesting to note that most of these varieties behave indifferently during specific situations. Just like human beings, dogs tend to suffer jealousy. The cute little furry friends can turn into annoying, green-eyed monsters in no time! However, there are few lesser-known facts about man’s best friend. This article will give you a comprehensive insight into these facts! Some are known theories, while others can surprise you extensively. Here are 25 Cool Dog Facts you wish you knew about:

25 cool facts: Fact #1 – No Guiltiness 

Do you know that dogs cannot feel guilt? Unlike jealousy, dogs are nowhere close to guilt. Research states that dogs respond differently when someone close scolds them. This is because they never feel guilt. Dogs look guilty only when they are refused something!

Fact #2 – Corroding Metals

Dog urine is a powerful solution that can corrode metals instantaneously. If you let your furry friend wee near a street lamp post, you are doing a “big” crime! This is because dog wee is acidic and can corrode the lamppost.

Fact #3 – EyeSight

Gone are the days when man believed that dogs could not see color! Well, dogs can see few colors other than black and white. Though not as sharp and vivid as man, dogs can see shades! This is because dogs have only 2 cones in their retina (humans have three). Conversely, dogs can see yellow and blue quite clearly. On the other hand, they cannot identify a difference between green and red.

Fact #4 – Untrained Doctors!

Dogs are untrained doctors! They can identify the presence of diseases quite easily. If something is going to be wrong with you, dogs can spot it. Researchers at the Schillerhohe Hospital proved that dogs can identify a wide range of smells (organic composites) that can state if a person’s body is working fine or not! Thus, your little furry friends can actually diagnose cancer and diabetes, too!

Fact #5 – Smartness Unleashed

Dogs can be as bright as a three-year-old kid. This is a declarative statement made by researchers at the American Psychological Association. Some dog breeds can remember and understand up to 250 words, whereas golden retrievers, German shepherds, and Dobermans are cleverer.

Fact # 6 – Wag, Wag, Wag!

Finally, dogs with wagging tails are not really happy. This is a golden myth that has been proved wrong! Tail wagging is a mode of language. Dogs mainly wag their tails to the right when they feel delighted. On the contrary, they wag to their left when they sense fear and discomfort.
