Dogs can make anyone smile. Here are some fun facts about dogs that will leave you smiling:

Dogs can sniff medical problems

Dogs can sniff out cancer, diabetes, seizures, migraines, and a number of other diseases. Because dogs have over 220 million scent receptors, dogs can smell things humans wouldn’t even think of smelling. 

Small dogs can hear sounds in higher ranges than big dogs

Head-size is a large predictor on how well a dog can hear. A study conducted by the University of Lincoln studied the hearing ranges from tiny chihuahuas all the way to St. Bernard's. The research showed that dogs with wider heads have lower sensitivity for higher-frequency sounds.

Dogs can smell feelings

Dogs have the ability to smell how you are feeling emotionally and can even adopt your emotions as well. A study conducted by University of Naples “Federico II” proved this to be true. They showed human volunteers videos that would make them feel sad, scared, happy, or neutral. Then they collected samples of the odors released by the volunteers and presented it to dogs. Surprisingly, the dogs exposed to the fear and sad smells were more anxious than the dogs who were exposed to happy or neutral smells.
