Having grown up with dogs I found myself very interested in “The Science of Dogs” There was a point in time when my family had three dogs of different breeds living in our house. The oldest was a yellow labrador named Breck (short for Breckenridge). A couple of years after adopting her we got a beagle pup named Daisy who was one of the smallest in her litter. After that we got a mutt named Sabrina who was a Black Lab and Chow mix which could be distinguished especially by her blue tongue, a prominent trait of the chow breed.
Each one of these dogs had some unique traits and mannerisms which I believe were inherited from their parents. Daisy the Beagle for instance, whenever she was outside, would keep her nose to the ground constantly in search of rabbits or squirrels which she had become quite skilled at catching. She would patrol across the yard with head pointed downward while baying loudly to indicate her position which is a trait that is very much a signature of the beagle and other hunting breeds. She was also a very hilariously domineering creature who would impatiently bark at me and look up towards the cabinet where her treats were kept. “The Science of Dogs” made mention of a trait that canines developed as they began to depend on humans in which they attempt to communicate through various means. The dog in the film, who was unable to get to a piece of meat locked in a cage approached a human and gestured toward the cage using head and eye movements. I especially enjoyed this part of the film because it reminded me of how Daisy used to act around me and my family before she passed away a couple of years ago. She was about 13 years old.
