Popular Dog Breeds 1900 to 1945

Since the early 1900s, the American Kennel Club has published lists of the most popular breeds.  But dogs that weren’t purebred, or that were not registered won’t show up on that roster.  
Four all-American dogs, the Rat Terrier, American Bull Terrier, Boston Terrier, and American Cocker Spaniel were commonly seen on porches of new suburban bungalows built with yards and gardens to accommodated a family dog, something of a new concept.

The Rat Terrier:  Until about 1900, any small dog that killed vermin for its keep was by default known as a rat terrier.  The loyal little dog, snubbed by UK Victorian era fanciers as nothing more than a "vermin killer of little consequence" was an American favorite.

The Boston Terrier was the first breed actually developed in America to be recognized by the AKC. The Boston Terrier was the most popular dog beginning1905 although he'd moved to second place by 1935.

The American Bull Terrier was a popular pooch at the turn of the last century, prized by the rich and famous, poor and not so poor alike. 

It’s ancestral stock was brought to the US in the 19th century by UK immigrants.  It was bred from terriers and bulldogs.  There are many dogs that are similar today. They’re informally grouped together and called bully breeds.

Nationalism leading up to World War I made the breed a favorite. The American Bull Terrier represented the USA, and patriotic sentiment intensified our attachment to the breed.  
The American Cocker Spaniel took over first place in 1936 leading the way as the most popular dog from 1936 through 1952.

The American Cocker was perhaps the
first working dog eventually bred
solely for companionship.

Autoimmune System and Cesarian Section Birth in Dogs

An number of dog breeds with excessively large heads must deliver pups via Cesarean birth. Breed clubs admit that 80% of births in the Boston Terrier, Bulldog and French Bulldog are by C-section. 

Because of the size  and shape
of the skull, most Boston Terriers
 are delivered by C-section.

 In vaginal birth, the fetus departs the womb completely sterile without a single microbe. Passing through the mother’s birth canal covers the baby with colonies of bacteria that kick-start the immune system.  Cesarean deliveries may contribute to an increase in autoimmune weaknesses because newborns lack the appropriate microbes.

An infant's diverse microbial community is essential to establish a healthy digestive tract, help shape the growing brain, and even protect from psychiatric disorders.  (

Even big dogs have skulls
relative to the size of their bodies. 

Do C-section pups start life lacking the microbes they would normally have picked up from vaginal delivery delaying the colonization of healthy microbes?
In 2009 the United Kingdom Kennel Club
 banned the breeding of traits
 that are cruel and disabling for dogs.
This includes the hallmark
deformed skull of the Bulldog.  

Because most of the health issues in these breed are due to their physical structure, the study of medical disorders connected to the slow introduction of protective bacteria is not well studied.
