Identifying the Origins

It is only by some general indications, since a rigorous scientific identification is difficult, even for those who possess anatomy notions and a morphological knowledge of all the canine races that exist. 

In general, a specialist can try to recognize the race of the progenitors for the conformation of the head and the behavior of the line; the color or the consistency of the coat, the weight, the height, the form of the ears and the body, they are data that, even providing some hint, they can be misleading elements for the reconstruction of a genealogical tree, although it is approximate. 

Let us look then at these crossbreed dogs and let us examine it coldly, as if has put on a white robe. 

Fox-terrier type
It is the most current crossbreed dog and easily identifiable, because even after many crossings it is able to maintain some fundamental features, as the size, the predominant white color and the black head, the short hair, the height that is between the thirty and the forty centimeters, the weight that doesn't overcome the 10 kilos, sometimes, the ears that they usually bend forward. The fox-terrier dog, besides conserving certain morphological characteristics, also maintains the attitudes and the intelligence of his pure ancestors. It is, therefore, a good hunter of small animals (foxes, rabbits and naturally mice), he barks when it is necessary and he knows how to be, at the same time, guard dog and an excellent partner. As this habituated to live inside the house for decades, he is considered an authenticate company dog. their crossbreed descendant well be good with the family and he wont allow to pass any opportunity to demonstrate his gratefulness to the master. This dog is usually robust, of having small or medium height, it resists the fatigue and the life well to the bleakness and it can overcome the fifteen years of age.

Lulu type
As the fox-terrier, these dogs maintain many characteristics of the race that of the one that they derive. They have a thick coat, they take the volute line, they have small and pointed ears, the typical fox muzzle and their coat can be white, reddish clear, close to the black or of several colors. As the lulu authenticate, these dogs are also endowed with a fine hearing and, to the first suspicious noise, they bark furiously; for that reason they are considered as good guard dogs. Inside the type of lulu they sometimes appear copies of short paws and lengthened body, of very cheerful, affectionate and very playful aspect that they love their owner in an almost excessive way. 

Shepherd Type
The shepherds that we see pass with their flocks generally possess crossbreed dogs. They usually call "guard's dogs" when they could raise themselves specialized pure dogs, which it would cost the same thing and they would be more useful. Anyway, the freedom that they grant to their dogs is pure or not, it causes crossings inevitably with crossbreed dogs that find in their incessant go and to come after the sheep. However, there are two shepherd types that they appear with more frequency in the world of the rural dogs: those that descend of the German shepherd and those that descend of the shepherd from "guard dog" (of ruffled hair in the whole body).

The German shepherd is also very common in the cities, since some not well informed proprietors make crossings among their dogs, believing that they are pure (and they are not ) for that , frequently, they appear defects that, in the new generations, they degenerate in definitely bastard characters, anyway, the shepherd exhibits a gray coat, gray yellow or gray black, he has a very rectangular trunk, ears not always erect, the typical muzzle of the wolf dog, although with some irregularity, a very high back and a stature different to the one that marks the standard . But very often preserve the excellent dominant moral qualities of their grandparents: it is valiant, easy to train, faithful and intelligent and, in consequence, it assumes guardian's functions quite well, of defender and friend.
