Filed under: Dogs care — Tags: , , , , — Cynara @ 7:19 am

dogsIn the domestication process, the dog is inserted in the human conviviality, for that, it is extremely necessary that it is socialized, so that it can interact with human beings in a coherent way and socially it accepts. When being socialized, the dog starts to have a harmonicer relationship with his human family. 
 
Considering that most of the attacks happens in family contexts and commonly they are addressed people and friends, the socialization becomes a more significant need. Through the socialization process, the dog doesn’t attack a known child when she invades his territory for not identifying her nor as threat, nor as prey. 
 
The phase of the life that is going from eight to sixteen weeks a critical point is considered in the emotional development of the dogs. In that phase, the dog learns with very more easiness and in a more intense and durable way what is safe or not for him. 
 
Dogs that until the 16 weeks they don’t have contact with people pass behaving as savages, what turns him unable to learn simple commands of training. 
 
The process of primary socialization is characterized by the positive presentation to the nestling (8-16 weeks) of all the controllable factors that will be part of his life. Those controlled factors are: people of different ages, toys and objects.

Race X Behavior

Filed under: Dogs care — Tags: , , , , , — Cynara @ 9:39 am

Will it be possible the behavior characteristic, how the aggressiveness, be transmitted for the following generation? 
 
In the same way that morphologic characteristics can be inherited of last generations, neurophysiological characteristics also can. Therefore, the genetic predisposition for several behavior problems can justify a possible association between aggressiveness and race of the dog. 
 
Such relationship can be justified with differences in the neurotransmitter levels or in the efficiency of their receivers in the Central Nervous System, favoring, or no, the appearance of problems as aggressiveness or anxiety. 
 
Some goods associate structural alterations in the brains of aggressive dogs and no aggressive. For instance, there is an increase of the number of receivers for androgenic in the tonsil in aggressive male dogs compared the no aggressive. There is also increase in the number of receivers in the front cortex, hippocampus and thalamu of the aggressive dogs compared to the no aggressive, etc. 
 
Those aspects, among other, they could find the favorable arguments to the association between race and aggressiveness, however it is not still possible to answer to the question a direct association there are been between aggressiveness and race.

Filed under: Cats care — Tags: , , , , — Cynara @ 3:29 pm

catThe domestic cats today are an evolutionary adaptation of the African wild cats, what does with that these possess several characteristics in common with the great wild felines, as the habit of walking using their cushions quietly plant, the technical assaults of hunt and them presence of retractable nails. However, crossings among different specimens turned them smaller and less aggressive, assisting like this to the objective of creating an small animal, capable to hunt rodents and to live in the same houses that the men. 
 
His older one ancestral known it is Miacis, mammal that lived there are about 40 million years and it possessed the habit of walking on the branches of the trees. The evolution of that animal created Dinictis, animal that already possessed most of the present characteristics in the current felines. 

The sub-family Felinae, that contains the domestic cats, appeared there are about 12 million years, expanding the starting from Africa until reaching the lands where now it is Egypt. Besides, they were the Egyptians the first people to adopt the cats as work animals and estimate. 
 
When the populations stopped being nomadic, the people’s life started to depend substantially of the agriculture. It was on that moment that the cats came to do part of the daily of the human being. For possessing a fort instinct hunter, those animals exercised an important function in the society: to end with the mice that invaded the silos of cereals and other places where the foods were stored. 
 
However, it didn’t delay so that some animals were transported secretly for other territories, doing with that the cats ended up increasing his inclusion area. When they arrived in old Persia, they also passed to be worshipped. There was the faith that when you mistreated a black cat, you took the risk of being mistreating a spirit friend, especially created to do company to the man during his passage in the Earth. This way, when harming a cat, the man would be reaching himself. 
 
In the course of time the cats passed to be considered fine animals, winning a good position of the social point of view. They were used besides as accessories in social events for the ladies. In that time the cat began to be modified for exhibitions, beginning like this the creation of pure races, with pedigree. One of the first races created for that purpose was the Persian, that it was known after his introduction in the European continent, accomplished by the Italian traveler Pietro Della Valle. 
 
The great first exhibition of cats happened in 1871, in London. To leave of that moment, the interest in exposing cats developed inside of standard rights spread for the whole Europe. 
 
Nowadays, the cats are one of the most popular mascots all over the world, serving the man as a good company animal and they still continue being used by farmers and navigators of several countries, as a cheap middle of controlling the population certain rodents. Due to the fact of his domestication to be relatively recent, when necessary, they easily can convert to the wild life, starting to live in wild atmospheres, where they form small colonies and they hunt together.

The origin of the domestic dog

Filed under: Dogs care — Tags: , , , , — Cynara @ 9:31 am

wolfFrom his origin the dog is submitted to the natural selection, through the adaptation to the environment and the artificial selection, through the human beings. 
 
In the beginning of the domestication, the human beings conserved those encourage less aggressive and less withdrawn, probably selecting those with morphologic characteristics that differed of the wild specimen, fact that it might have made possible the great morphologic variety found in the domestic dogs nowadays. 
 
The domestic dog has the wolf as ancestral. Specimen of that species were, along the time, being selected for several aptitudes, being today, an animal with larger potential of social cognition that the wild wolves, standing out even of great primates in certain tasks that depend on the reading of human corporal signs. 
 
The first associations between men and dogs were found in China and they remount there are 150.000 years. There are about 10.000 years, when leaving of being nomadic and hunter to be producing and creator of his food, the man needed to tame the ancestral of the dog to aid him in the hunt and, later, in the care of the cattle. 
 
The fixation of the racial patterns only appeared starting from the Century XVI for the hunt dogs and it continued along the centuries. 
 
The races are fruit of natural selection, artificial selection and of the crossing among animals of different patterns. The recognition of the races depends on the people’s organization that create the dogs in associations or clubs, us which their members establish morphologic patterns and behaviors. 
 
Among animals of the same race different lineages can exist, that they are developed by the creators starting from the selection.
