Whiskers, also known as vibrissae, are highly sensitive tactile hairs that help dogs detect changes in their environment. They can sense air currents and vibrations, allowing them to navigate and understand objects nearby, even in the dark.
Dogs experience REM (Rapid Eye Movement) sleep just like humans, and during this stage, they dream. Puppies and older dogs tend to dream more frequently. If you’ve ever seen your dog twitching or moving in its sleep, it’s probably dreaming.
