Dogs can be such a mysterious creature.  I absolutely love observing how they interact with their handlers
I love dogs.  Do you know anything about search and rescue dogs?  
Indeed, I own a German Shepherd. They are well versed for search and rescue.
Amazing!  We had a German Shepherd mix.  I am also fascinated by the St. Bernard, who are apparently from the Alps, around Switzerland, France, and Italy.
St Bernards are infamous for search and rescue.  I remember in the movies they were the preferred breed for the colder winter weather
Yes, they are built for it!  While we are on the subject of Dogs, have you seen A Dog's Purpose., based on the novel by W. Bruce Cameron?  I was too sad to watch it.
I have not seen that movie, but I absolutely love movies in which dogs are the central character and get into various types of mischeif.
Dogs have so much personality.  It's incredible that normal dogs have incredible social and cognitive abilities.  They really are humanity's best friend.
