Dogs have an incredible sense of smell that allows them to detect individual scents from miles away.
Some even get trained to detect medical conditions like low blood sugar or seizures.
Just like human fingerprints, every dog has a unique nose print.
Some research studies and organizations even use them for identification purposes.
Certain dog breeds, like Greyhounds, are so fast that they can outrun a cheetah in short sprints.
They can reach speeds of up to 45 mph over a 7-mile stretch.
Around 20 minutes into REM sleep, dogs generally begin to dream.
You’ll often see their legs twitch or paws move, mimicking activities they do when awake.
Dogs often favour one paw, similar to humans being right or left-handed.
You can find out which paw they prefer by offering them a toy or treat.
