• Dogs have a special reflective layer in their eyes called the tapetum lucidum – This helps them see in low-light conditions.

• Dogs can track smells that are days or even weeks old – Making them great for search-and-rescue missions.

• Dogs’ noses have unique ridges that form a print, just like human fingerprints – No two dogs have the same nose print.

• Dogs can detect heat with their noses – A special ability found mostly in hunting breeds.

• Dogs hear frequencies up to 65,000 Hz – Humans can only hear up to 20,000 Hz.
