History of the Chihuahua Breed Standard To Include Bob tail  
 
This page is an endeavor to honor the history of our beloved Chihuahua's breed standard, and to hopefully make it more readily 
available reading for all Chihuahua enthusiasts. Additionally, we offer these official standards in an attempt to educate the  
misguided, and ill-advised, who persist in blathering malicious misinformation concerning the bob-tail Chihuahua. 
 
The standards are listed chronologically from the earlier on, to present day. Through each revision, the Chihuahua Breed Standard 
has made some notable changes, to include making the bob-tails a disqualification for the show ring. However, the earlier standards  
clearly state -- the "born" bob-tail was common, and not disqualifying....

Quoting renowned Chihuahua breeder and Judge Ida H. Garrett, from breeder,  
exhibitor Russell E. Kauffman's book "The Chihuahua" copyright 1952 ~ 
 
"Ida Garret declared that the peculiarity of this breed is in the tail, not in the molaro as many believe. She says  
"The tail is considered peculiar when one often finds a meaty or fat spot or lump usually mid way in the tail. 
Below this spot is a break, often bearing a resemblance to having been caught in a door. Also the tail frequently 
breaks off entirely at this point, leaving a bob tail." This seems almost incredible, yet we see numerous bob tails, 
which are not disqualified if so born." 
 
 
Quoting from breeder, author "Tressa Thurmer's" book "Pet Chihuahua" copyright 1962 ~ 
 
"Tail - moderately long, carried sickle either up or out, or in a loop 
over the back, with tip just touching the back. (Never tucked under.) 
Hair on tail in harmony with the coat of the body, preferred furry in 
smooth coats. In long coats full and long as in a plume. A natural 
bob, or tailless is permissible if so born."

Chihuahuas born with bob, or kinked tails are not novel, nor rare, nor freaks of nature. These tails are the 
result of "a complex combination" of recessive gene types. Their Chihuahua ancestors have been passing them 
down for at least 80 years, and most probably longer. Therefore, even the most responsible breeders, who exercise 
meticulously selective breeding programs are not immune to the possibility of having a bob-tail puppy.

Forequarters - Shoulders - Lean, sloping into a slightly broadening support above straight forelegs that set well under, giving a free play at the elbows. Shoulders should be well up, giving balance and soundness, sloping into a level back. (Never down or low.) This gives a chestiness, and strength of forequarters, yet not of the "Bulldog" chest. 
 
 
Feet - A small, dainty foot with toes well split up but not spread, pads cushioned. (Neither the hare nor the cat foot.)  
 
Pasterns - Fine.

The legs, both front and rear, will tend to converge slightly toward a central line of gravity as speed increases. The side view shows good, strong drive in the rear and plenty of reach in the front, with head carried high. The topline should remain firm and the backline level as the dog moves. 
 
Temperament - Alert, with terrier-like qualities.
