Dogs are canine creatures that could be domesticated.


According to the Newsline column on the front page of the October 22, 2015 issue of USA Today,[1] a talented Border Collie called Maddy, who was a music video star and could ride a hoverboard, had her own one hour television special on the Canine Sports Network that same evening.

Automatic dog-walkers were invented between 1985 and 2015 to take the mundane task of walking the dog out of the owner's hand and entrusted to an autonomous hovercraft, while suspended animation kennels were developed during the same period with the intent to keep dogs and other pets in general occupied when their owners were away.

Dr. Emmett Brown's sniper rifle in 1885 apparently enabled him to "shoot the fleas off a dog's back at 500 yards", with the aid of the large telescope mounted onto it as a sight. Fortunately, much to the relief of any dogs that happened to be around Hill Valley at the time, Doc did not put this to the test.

Doc himself owned several dogs over his lifetime, all named after famous scientists. In 1955, Doc had a dog named Copernicus. the third in the line of his ongoing theme.[2]

In 1972, Doc had a dog named Galileo, who he used as a test subject in his garage for what Marcus Irving assumed to be "an anti-gravity field", but was actually what Doc termed an "inertial buoyancy displacement convector".

In 1985, Doc had a dog named Einstein. At some point, he made an automatic dog feeder for Einstein.

Edna Strickland had a great deal of contempt for dogs, and even had them banned under the Hill Valley Code in the 1986G timeline on the grounds of them carrying disease and stealing shoes. Extending to Edna's dislike of dogs in the 1986G timeline, the Hill Valley Courthouse had two dog statues.

After several more revisions to the timeline, she had taken a liking to dogs and even walked Einstein on a regular basis.

Before the dog ban, George McFly and Lorraine considered getting Marty a dog to teach him some responsibility. Biff Tannen had a lot of dogs which kept the neighbors up at night, attacked the elderly and ate the squirrels at the park. It was apparently because of his dogs that Edna went ahead with the ban, but Lorraine believed it to be an excuse.

Leech himself was allergic to dogs, and would often use his allergies as an indicator of one being nearby. Whether or not he was allergic to dogs in the original 1986 is unknown.

Behind the scenes[]

  • When recounting that she met George McFly when he got hit by her dad's car, Lorraine described it as her future husband being helpless like a little lost puppy. This applies to the timeline before Marty traveled back to 1955.
  • In the trilogy, dogs were heard more often than they were seen. The sound of barking dogs can be heard in the background of Back to the Future in various scenes:
    • As Marty is walking into his home in 1985, listening to Biff telling George, "I can't believe you loaned me your car without telling me it had a blind spot!"
    • On the Twin Pines Ranch, home of the Peabody family, in 1955 after Marty crashes into the barn, as the lights are coming on in the house. Also, a sign reading BEWARE OF DOG is attached to the first post of the chain-link fence at the entrance to the dirt access road leading to the ranch.
    • After Marty has been hit by Sam Baines's car, while George is running away.
    • While Marty is inside George's house in 1955, dressed as Darth Vader.

Also, in Back to the Future Part II, a pack of dogs are roaming Lyon Estates in 1985A.
