Operations Manual for the Xoloitzcuintli
author - Amy Fernandez
E-book Price USD $7.99
Revised 2011 edition - with many more photos.
The complete illustrated guide to the Xoloitzcuintli, for judges, breeders and owners.
This e-book provides an illustrated, in depth examination of the Xoloitzcuintli breed against the standards that apply in its home country of Mexico, and as used by the American Xolo club.
Xolo owner, breeder and judge, Amy Fernandez, has many years of experience in owning and judging this breed, and has judged the Mexican Xoloitzcuintli specialty show in Tijuana.
Also a highly experienced author and journalist, Amy has, with this book, created the serious Xolo lovers bible.
OF CONSTRUCTION AND EVOLUTION OF TYPE
breeding sometimes seems more complicated for hairless breeds,
but in reality, the same rules apply. The hairless mutation represents just one
facet of the process. Mutations—spontaneous genetic changes—are the ultimate
source of genetic variation. Without them, evolution, or selective dog breeding,
would not be possible.
selection forms a species to fulfill a specific function. It is the breeder’s
job to apply the same principles to artificial selection. No matter which
selective process is directing a breed’s evolution, exactly the same genetic
laws apply to the same thirty-nine pairs of chromosomes.
breeding and outcrossing will provide a temporary barrier to health problems,
but this approach will never offer any control or predictability to influence
the type of dog you are producing. These dogs may be healthy, but the tradeoff
is complete unpredictability in conformation, behavior, and genetic health.
understanding the transmission of various breed traits,
you can create a bloodline that will predictably conform to your expectations.
Most of the genetic traits that we are seeking readily respond to
straightforward selection. Decisions that you make for your breeding program may
demonstrate results in one generation, will likely show results in the second
and become predictably set into your line by the third.
first and most important step in breeding is a clear understanding of the
elements of type that define your breed. Form follows function; this concept
provides a logical framework by which to evaluate every trait.
breed traits do not develop randomly or independently.
one will enhance or impede functionality. Not every type found in a breed is
equally functional. Breed function dictates the parameters of type. Evaluating
variations within the context of functionality will clarify your breeding
defined as the appearance of breed traits versus soundness, the ability to
perform a function, is a perennial topic of debate.
rationale presupposes that any breeding program must begin from a compromise
either/or position, as if type and soundness were mutually inimical concepts.
Accepting this faulty line of reasoning instantly limits your possibilities for
success. If you understand the evolution of your breed’s type and continuity
of construction, these concepts will become mutually reinforcing. More
importantly, the dogs that you create will be prepotent for these traits, and
capable of reliably transmitting them to the next generation.
basic premise of animal breeding is the fact that undesirable traits are more
often produced by recessive genes, because unwanted dominant traits are
automatically selected out of the gene pool as they appear.
