…are starting out with a new puppy or dog: Super Puppy Book
Not all puppy advice applies equally to all puppies. Xolos are individuals and the owner must use their judgement as to what seems good for their dog, what works the best for it. Read lots of material about what you are doing and exercise your best judgement.
…not a recent article but I am sure that many of you have not read it.
…makes better dogs. I urge all breeders to read this article and carefully work these exercises into their time that they spend with their puppies. (http://www.esmondrott.com/rearing.htm) “DEVELOPING HIGH ACHIEVERS” Originally published as “Early Neurological Stimulation” by Dr.Carmen Battaglia.

…show dog and earned many championships. He sired some very wonderful pups here and then went to live in a home where he became a therapy dog for his new owner. His owner has written a very nice booklet about him and about Xolos in general. It is entitled XOLOITZCUINTLE “Sho-low-eets-queen-tlee”.

Article by Dr. Valadez: Findings from the Pyramid of the Moon
Mesquite lives in Beautiful British Columbia with his co-owner, Debbie Cornell-Charneski, a professional handler. Mesquite, born Aug 8, 2008, is sired by Mexican Champion Allende out of the Multi-Champion Techutli.
Quito, as he is fondly referred to, has the excellent blend of the elegant substance required of a standard Xolo. His almond shaped amber eyes are set into a correctly proportioned head which is set onto an elegantly arched neck. His ears are well set, shaped and compliment his head. With proper height to body length ratio, level topline, slightly sloping croup and correctly set and carried tail, he is a lovely example of the breed.
The title of the article is “A Mutation in Hairless Dogs Implicates FOX13 in Ectodermal Development” The researchers are from Sweden, Finland, Swizerland and the Broad Institute of Harvard U. and MIT The people from the University of Bern in Swizerland seem to be the prime researchers. They are Cord Drogemuller, Elinor Karlsson, Marjo K. Hytonen, Gaudenz Dolf, Kirsi Sainio, Hannes Lohi, Kersten Lindblad-Toh and Tosso Leeb.
The phenotype (physical appearance) of the hairless dog’s in the Xolo line is classified as Canine Ectodermal Dysplasia. This is the near complete absence of hair and the effect on the teeth.Teeth and hair are classified as ectodermal appendages, because they form very late in the development of the fetus. There are also some alterations in some of the exocrine glands in the human form which are not severe in the living dogs. This might also explain why some hairless dogs sweat through their skin because in this condition in humans the sweat glands can also be affected.
Ectodermal dysplasia in humans is a disorder involving two or more of the ectodermal structures, which include the skin, hair, nails, teeth, mucous membranes and sweat glands. How an individual is affected varies. For example, in one individual the hair and nails may be affected, while in another the disorder may involve the sweat glands and teeth. Each combination is considered a distinct type of ectodermal dysplasia.
They traced the gene to the 17th chromosome on the dogs where a sequence that is part of what is known as a FOX gene is duplicated. The Fox family of genes (which have nothing to do with foxes) are an important group of about 50 genes that encode for developmental regulators. This duplication is only 7 base pairs long but acts as an early “stop” signal for the production of the regulators. With only 1 gene the amount of the regulator is decreased but appears to be completely missing in the dogs with the two dominant genes. The lack of this regulator is thought to be the reason why the homozygous pups die.
The study was done using 140 hairless dogs, Chinese Crested, Xoloitzcuintle and Peruvians. The duplication was found in all of the dogs. When they tested coated dogs of the three breeds (55) and 32 other dogs from 19 other coated breeds there was no duplication on the gene.
They commented that “This study illustrated how the extreme morphological (body type) diversity of dogs can be harnessed to gain new insights into developmental biology.”
A Repeat… Our beautiful Opoa won Best of Breed for Standard Xolos at the show in Puebla this past weekend, both days. Thank you to Judge Mauricio Martínez and Judge Manuel Rangel for seeing the beautiful balance and proportion of this wonderful Xolo female.
Just getting around to posting this up…

Hairless Breed Shines at World Dog Show
MARCO HERNANDEZ has given his permission for me to post the following on my dogblog. It is a very good explanation of the hairless situation/mutation. He has given an English translation. Thank you, Marco.
When we hear the word mutation, our mind make us think about abnormal, horrible beings. However, altough, certainly not in such a spectacular way, mutations form pat of every living being´s normal life, even more, we all are mutants, how can this occur???
DNA is the molecule of heredity. Each time that a being repoduces or a cell multiplies in our tissues, Dna copies are created. This molecule can be described as a code or sequence, represented by letters: G, C, T. A. Every three letters a significant unit appears, thus we could have the following sequence: Continue reading Article on Hairless mutation, Marco Hernandez
