In the same way as it happens with the Zaino horse, the tordillo or gray horse is one with a characteristic and differentiating coat regardless of the breed to which the equine belongs.

The gray fur
A relevant aspect in the equine world is the fur (understood as the set formed by the hairs of the body, the mane and the tail) that can convey essential information about the animal to us such as measuring your health or assessing your ability to serve the human being.
Phases of the process depigmentation
We commented at the beginning of the article that gray horses are usually born with a dark coat that is lightening. Taking into account this depigmentation process, in which equine skin and eye pigmentation remains unchanged, can be established phases according to the moment in which the coat is found of the gray horses:
Phase 1: The hatchling coat
The gray foals are born with him normal base coat, usually dark in color, with rare exceptions that can be born with an advanced gray phase or completely white. Often the eyelashes and around the eyes indicate their character of thrushes presenting white hairs in these areas.
Phase 2: Fledgling Thrush
With the first coat shed some white hairs appear on the body. These are more numerous on the head, while the mane and tail can be either whiter than the body or darker.
Phase 3: Rolled Thrush dark
White hairs they turn more numerous with successive molts after the first. Appear grouping together and forming small white spots on the ground coat which is usually darker. These spots can be round in shape and relatively large in size. These spots are separated from each other by dark fur. Hence the denomination of "wheeled thrushes".
In this phase white hairs predominate compared to dark ones, giving the equine a clearer appearance. This increase in white hairs makes the size of the spots of this color increase and begin to merge leaving the dark hair parts isolated with each other and, in some cases, with a rounded shape.
Phase 5: Muscat thrushes and atruitats
Continue on increased white hairs andconsequently, the decrease of dark hairs until only small dark spots remain. It is called "muscat thrushes" if the base coat is black or brown and "tordos atruitats" if the base coat is chestnut or chestnut.
Phase 6: Gray or White Thrush
In this last phase of the depigmentation of gray horses, all fur (which includes the tail and mane) becomes completely white. In some cases a little more particular, a regression can occur why after this last phase, equines show pigmented areas again.
Varieties of the gray horse
In addition to the different names according to the depigmentation phase in which the horse's fur is, we can find different varieties in terms of coat color of the gray horses. Some denominations of the varieties are similar and related to the phases.
- Light gray, It is one that has some black hair on the neck, back and rump, on a white hair cape.
