What are the common genetic disorders of VIP guests?

In modern urban life, more and more dogs as companion dogs into our family, in which the VIP with their beautiful, docile, understanding and smart to get the majority of friends love, their health problems also make the majority of friends worried, in addition to common infectious diseases, we take a look at the poodle today what genetic diseases? 1. Patellar dislocation in dogs refers to the patella in the movement of the knee extension and flexion, suddenly out of the trochlea, can be divided into internal dislocation and external dislocation, the most common clinical dislocation is internal dislocation. Symptoms and grading: The affected dogs can be divided into 4 grades from mild to severe broken by clinical symptoms and course of the disease. Grade 1: Most of them have no clinical symptoms, but when the leg is extended, the patella will be dislocated by pressing the hand, and the patella will be naturally restored after the hand is loosened. Occasionally, mild jumping walking is seen. Grade 2: When most dogs lie up, they often break by jumping because of knee curvature and patella dislocation, but most can be recovered. Grade 3: patella dislocation most of the time. As the disease progresses, the medial quadriceps muscle group is displaced, the femur and tibia are deformed, the ligaments supporting the patella are extended, and the trochlear groove is shallower. Reposition the patella with your hand and release it as soon as the leg bends. Grade 4: The proximal tibial platform has 80-90° rotation, and the patella dislocation cannot be manually reduced. With the further deformation of the bone, the affected limb is reluctant to carry weight and walks in a curl position. When both hind limbs are diseased, the affected dog walks in a squat position. Cataracts A cataract is a change in the lens in the eye. Normal crystals are transparent and their main role is to help focus light and images. When a cataract forms, the lens becomes cloudy or blue or white. Generally, cataracts are classified as mature or immature. Immature cataracts are those in which only part of the lens is affected, so little vision is affected. If the cataract progresses to the mature stage of cataract, the entire lens will be affected and vision will be lost. Many animals may also respond to light or moving objects, and hereditary or congenital cataracts can occur at any age in the animal, with different ages of onset for different breeds. There is a great difference in the age of onset and the rate of development of different varieties! 3. Femoral head necrosis Recapes disease (aseptic femoral head necrosis) : The main cause of femoral head necrosis in dogs is the bone ischemia caused by the obstruction of the blood flow of the femoral head and the destruction of the femoral head, so it can generally become ischemic or aseptic necrosis of the femoral head. Epilepsy: Primary epilepsy is also known as spontaneous epilepsy or true epilepsy. It is generally believed that it is related to genetic factors, resulting in increased sensitivity of the cerebral cortex and subcortical center to external stimuli, which is easy to cause the occurrence of the disease. 1. Major seizure type. The dog suddenly falls to the ground, convulses, occurs tonic or paroxysmal spasms, the whole body is stiff, the limbs are extended, the head and neck are bent to the back or one side, and sometimes the limbs are swimming. With muscle twitching, loss of consciousness and consciousness, mouth foaming with closed teeth. Eyeball rotation, sclera, pupil dilation, nasolabial tremor, urinary and bowel incontinence. Seizures last from a few seconds to a few minutes. In the later stage of the attack, the convulsion phenomenon disappears, consciousness and sensation recover, the affected dog automatically stands up, showing fatigue, ataxia, and mental depression. 2. Minor seizure type, sudden occurrence of transient disturbance of consciousness, motionless, slow or no response, spasticity symptoms are mild and brief, mostly manifested in local, such as eyelid flutter, eye rotation, lip tremor and so on. The length of the interval between the onset of epilepsy carbuncle next, some attacks several times a day or several times, and some intervals of several days, months, or even more than a year, in the interval of its performance and healthy dogs are exactly the same. 5. Cryptorchidism Under normal circumstances, animals before and after the birth of the testes from the abdominal cavity down to the scrotum, if not down to the scrotum, the formation of cryptorchidism. It can occur in dogs and cats. There are two types of cryptorchidism, one located in the groin (at the root of the thigh) and the other in the abdominal cavity. These two conditions are called inguinal cryptorchidism and intra-abdominal cryptorchidism, respectively. Under normal circumstances, the testicles are located in the scrotum, and the muscles in the scrotum can be contracted to connect with the testicles, the main role is to raise and lower the testicles, to regulate the environmental temperature of the testicles. Under normal circumstances, the temperature of the testicles is slightly lower than body temperature. However, when there is a cryptorchidism, the temperature of the testicles cannot be adjusted, and the temperature in the body is higher than that in the body, resulting in a higher ambient temperature for the work of the testis, which leads to the malformation of sperm in the cryptorchidism and the prone occurrence of cancer in the testis. Animals with unilateral cryptorchidism, as long as the external testicle form is healthy, have reproductive ability; Some animals also develop bilateral cryptorchidism, in which animals are unable to reproduce. Some patients with cryptorchidism, cryptorchidism lesions, secreting hormones, resulting in external healthy testicles also lesions, at this time also lose fertility. And due to the disturbance of sex hormone levels will lead to a series of lesions throughout the body, such as: hair removal, skin thinning, genital atrophy. The course of disease is longer, can cause prostate cyst, testicular cancer when not timely surgical resection of the diseased testicle, can cause serious hematopoietic dysfunction, anemia, hemagglutination and so on. When the cancer appears and spreads, it can be life-threatening.
