There are over 340 different dog breeds worldwide, each with its own unique characteristics, size, and appearance.
Dogs have an extraordinary sense of smell. The area of their brain dedicated to analyzing smells is proportionally 40 times larger than that of humans.
Dogs communicate not only through barking but also through body language. Tail wagging, ear position, and facial expressions all convey different emotions and intentions.
Just like human fingerprints, a dog's nose has a unique pattern. It can be used for identification purposes.
The lifespan of a dog varies greatly depending on its size. Small breeds tend to live longer than larger breeds. On average, dogs live between 10 and 13 years.
Dogs experience similar sleep cycles as humans, including the REM (rapid eye movement) stage associated with dreaming. You may notice your dog twitching, paddling, or even barking in their sleep.
Dogs were likely the first animals to be domesticated by humans. The process is estimated to have begun over 20,000 years ago.
