For in the world of the last century created more than four hundred of various breeds of dogs: decorative, guard, fighting …
Their representatives are distinguished in everything: in body size, coat color, conformation characteristics, temperament, habits and food preferences, even on “creativity.”
But all of them, as diverse, from the pocket of the giant dog to dog, united not only love us, their sincere friends and admirers. They are characterized by the same ailment. Well, so much easier to arm ourselves against them and the opportunity to help our pets.
To understand – means to win
The mechanism of occurrence of genetic disease is very difficult. It is equally difficult to identify them and then treat. But when the genetic malfunction occurs “under the direction” of the dominant gene, the main drawback of this mechanism becomes his advantage.
Dominant hereditary anomaly dogs
One of the parents gave to her puppy abnormal dominant gene, it becomes obvious culprit deviations clearly marked externally. But in the future should not expect the unexpected “catch”, as is the case with the recessive genes. They often appear in the offspring of such vehicles in the next generations.
Choosing their future pet litter, the buyer can be assured in the main – among the puppies for sale it is unlikely to meet the owner of the dominant genetic abnormality.
They express carriers identify and discarded in the first place and is excluded from further breeding. In general, dominant hereditary diseases in dogs are extremely rare.
Recessive genetic diseases
The most common of all dog breeds there is recessive anomalies, known for their cunning, secretive “behavior.” This, the most common syndromes are susceptible to many of the body’s system of dogs, namely:
Its striking, first of all, hereditary diseases such as elbow dysplasia and hip splitting vertebrae disease Legg – Perthes, the displacement of the intervertebral disc (discopathy) and intervertebral hernia, craniomandibular osteopathy (CMO), a variety of defects in the tail;
• nervous system.
Her real scourge in most breeds of dogs became epilepsy ;
• muscular system.
Widespread umbilical hernia;
• reproductive system.
The most common animals suffer cryptorchidism, monorchism, and against the background of the anomaly is not only one or two undescended testicles, but also systemic violations of the body;
Various defects bite, missing teeth also talk about general constitutional weakness of the animal;
• visual system.
Primary lens luxation (PLL), progressive retinal atrophy (PRA), cataracts – the most common hereditary diseases, depriving dogs of view;
Hereditary deafness is caused by a gene, also associated with the genes of white coat color and blue-eyed.
Methods of diagnosis and control of genetic diseases – X-ray diagnostics (in particular, myelography), genetic testing (BAER-test, PLL-test), surgical intervention is strictly balanced power system.
The combination of “genetic abnormalities” creates the impression of something necessarily negative, unavoidable. But many hereditary diseases, fortunately, amenable to correction.
The main condition of success – the timely detection of genetic abnormalities in the dog with the help of comprehensive early diagnosis of major body systems. And the easiest way to avoid hereditary diseases – to choose the right parental couple.
