Why Doesn't Trump Have a Dog?

I'm having a hard time getting over the fact that Trump doesn't have a dog. 

Yes, I know that there are far more important and weighty things to be concerned about..but the man not only doesn't have a dog, according to informed sources he has no known pets. This makes him an outlier among Presidents. He is the first President not to have a dog since William McKinley over 116 years ago( making his assassination a cautionary tale). Trump is also only the second President in history not to have any pets whatsoever, joining James K. Polk for that dubious honor. 

The following is a partial list of some of our more famous Presidents and their pets. Make of it what you will.

George Washington. The father of our country had eight dogs, three staghounds, four Black and Tans and one greyhound which he wittingly named, Cornwallis.

Thomas Jefferson had two bird dogs, one named Buzzy, and the other who went mysteriously unnamed.( Probably from the Hemings side of the family).

Andrew Jackson is the president often sited by historians trying to find an antecedent to Trump. Ironically, Jackson also had no dogs. He had a parrot which he taught to swear and two fighting cocks. Coincidence? I think not!

Abraham Lincoln, the Great Emancipator, had two dogs, two cats, one turkey and one rabbit. One of his cats he playfully named "Dixie" and he often said of her that she was smarter than his entire cabinet put together!

Theodore Roosevelt, besides being a President thought worthy enough to be placed on Rushmore, was also basically a zookeeper. This crazy man had five guinea pigs, two ponies, ten dogs, two cats, a hen, a lizard, a garter snake, a small bear, a rat, badger, pig, rabbit, hyena, barn owl, and a one legged rooster.

FDR had seven dogs varied in breed from a Scottish Terrier to a bull mastiff.

JFK. Ten dogs.

LBJ. Six dogs.

Nixon. Four dogs, including Checkers, made famous by the Checkers Speech.

Ronald Reagan had six dogs, including the White House' first ever Golden Retriever.

Bill Clinton. Buddy, the chocolate lab.

George W. Bush. Four dogs.

Barack Obama. Two dogs, Bo and Sunny.

The love of pets, especially dogs seems to be clearly a bipartisan phenomenon. No matter their political affiliations, our presidents have been nearly unanimous in their affections for pets. Which brings me back to the current occupant of 1600 Pennsylvania Avenue. 
What are we to make of this petless man? Certainly there is nothing intrinsically wrong with not having pets. I get it, not everyone likes animals. But this is the President of the United States we're talking about here. After a long, insane day of leading the free world, I would like to think that my President at least enjoys the quiet, unconditional love of a fine 
dog or even the pseudo affections of an oblivious cat. If Trump were to get a dog, what breed do you think he might settle on? Probably not a Chihuahua.
