TWISTED MOUTH / WRY MOUTH / WRY JAW/ DISTORTED BITE / CROOCED JAW: * WHY EXCLUDE FOR BREEDING !!! *

(GENETICALLY RECESSIVE OR DOMINANT)


*A genetic defect that has never been bred*

This occurs in the genetic material in sperm or egg, then these effects are transmissible to offspring.


If one side of the jaw (right or left, not top or bottom) with a higher growth rate than the other, then there is a rotation of the snout This is called a twisted mouth / Wry Jaw called.


The spinal column is, in turn, a part of the skeleton.

The construction of the skeletal system begins at an early stage of embryonic development.

It develops from one of the three germ layers, the so-called mesoderm.

From this same germ layer also takes the place of, among other things, the development blood vessel system ((including the heart) , the muscular

system and the genitourinary apparatus (kidney and urinary tract and reproductive organs).

The whole development of the fertilized ovum to pup, as well as the development of the animal is then sent in principle and monitored by the genetic factors that has a puppy in it.

For the development of the spine have been demonstrated in the mouse for 20 hereditary factors.

Also for the skeletal development after birth are again many genetic factors responsible.

All in all a complicated process that can best go wrong.


Mutations occur regularly. This may result in, among other genetic defects.

This occurs in the genetic material in sperm or egg, then these effects are transmissible to offspring.

Genetic abnormalities are not always expressed in the phenotype. The reasons for this are several.

The mode of inheritance (recessive or dominant) there is one of, but also the degree of heterogeneity or variability in the set of genes involved.


But if a dog with a deformation, it can be "little defect" seriously affect his descendants.  Also, other parts of the spine.  There are dogs born with deformed neck, thoracic dorsal and lumbar vertebrae.  Cases of puppies with a cleft palate, hydrocephalus, kinked tails, deformed ribs, too much or too little teeth and short legs (from knee to foot).


As a result of the interactions between different genetic factors may arise defects in other organ systems that have been developed in the mesoderm.

Examples include the persistent (lasting) embryonic blood vessels, a septal defect (defect of the heart septum), ectopic ureters (tubes from kidney to bladder are in the wrong place), the absence of the anus and cloaca formation (anus and urethra have one common output ).

These abnormalities are usually categorized as congenital anomalies which would not hereditary but can be dangerous for breeding.

* IF YOU WANT TO BREEDING BUY NOT A PUP WITH A TWISTED MOUTH / WRY MOUTH / WRY JAW/ DISTORTED BITE / OR CROOCED JAW, AND EVEN FROM PARENTS OR ANCESTORS WITH THIS PROBLEM !!! *
