In the 1986 cult-classic film, “Ferris Bueller’s Day off” there is a scene when principal Edward Rooney (played by Jeffrey Jones) tries to break into Ferris’ house to catch him playing hookey red handed. Of course, no one his home except The Bueller family’s dog – an unnamed Rottweiler who proceeds to chase Rooney out of the house. Later on, Rooney is able to knock the dog out with a floral arrangement that was delivered for the ailing Ferris (don’t worry – they just put the dog in a “play dead” command while they had the debris around him). Don’t worry, the dog did get his revenge when towards the end of the film, Ferris’ sister, Jeanie, slams a door shut with Rooney in the back yard. Of course, this wakes the dog up and you can hear a “vicious” attack going on behind the door with Rooney screaming.
Rottweiliers are commonly used in movies as “tough” dogs due to their bulky appearance and reputation when in reality a well bred and trained Rottie is actually a very sweet and cuddly dog but they can be protective of their family and can be trained to look aggressive.
At the age of six weeks (a little early IMO) Captain Johnathan Archer had his trusty English Beagle, Porthos. In Season 1 Porthos was played by a male beagle named Prada, whom also played a beagle named Lou in the film Cats and Dogs (voiced by Toby Maguire). In later seasons two female beagles shared the honor, Breezy and Windy (although Porthos was always a male).
In one of the final episodes of Enterprise, “In a Mirror Darkly” (a “evil twin universe episode”), Porthos was replaced with a Rottweiler. While they tried to find a dog that would be a polar opposite to the Beagle (and Rotties do have that look), on set reports that the Rottweiler was even a bigger baby than the Beagle – writer Mike Sussman noted that he was “The sweetest dog I Have ever met”.
In the new Star Trek Film (2009) there is reference to Montgomery Scott having a “transporter accident” with Admiral Archer’s dog. I highly doubt it was the beloved beagle since he would have been over 70 years old when Scotty was born. 🙂
