Many people think that dogs tilt their heads in order to look at something more carefully. This isn’t true though. The truth is that dogs tilt their heads because it helps them sniff out danger. It’s a natural reflex which allows them to detect odors – whether they be good or bad smells – through their sense of smell. When a dog tilts his head, he uses his nose to breathe deeper into the air around him. When they feel an odor coming from somewhere nearby, they will often sniff the air with their head tilted slightly upward. Dogs also use this method to communicate with each other. If one dog tilts his head, another dog may follow suit. This way, they can tell who is speaking and what they are saying. If you want to understand more about how dogs communicate, read on as we discuss the science behind why dogs tilt their heads when confused.
