2- About genetic diseases and prevention, I will introduce them in the copy later.
3- About what to pay attention to when buying, the following text will be introduced in part. Here, I would like to add some personal opinions about picking dogs for your reference. I have two basic principles when buying a dog: one is fate, and the other is appearance. The reason why fate is put in the first place is that if you want to get along with it day and night in the future, you must have the best first impression on each other: not only do you have a good impression on it at the first time, but it also has a good impression on you at the first time, which is very important (absolute personal opinion); Buying a dog you like is much better than buying a dog you like-this is the fate with dogs (when I went to pick female guests, they were 6 males 1 female. Originally, there was a DD that was the strongest, with unique personality and competitive potential, and I liked it very much. But this MM was very friendly and happy as soon as she saw me. She came to play with me. When I was holding her, she kept looking at my eyes, and then stuck out her tongue, feeling that I was her favorite owner, so I finally chose MM over the one with the best looks. As for appearance, I usually look at eye size (the bigger the better), nose (the darker the better, but the female is not necessarily so black), lips (the darker the better, but the female may turn red, as if the female cat's lips are all red), ears (the higher the better), head shape (to be complete and full), skeleton (the bigger will be more powerful) and standing posture. Then see if the ears are too deaf, the mouth is clean, the eyes are clear, and the anus is clean; Look at its running posture; These are all basic appearances. As long as they are qualified, they are basically dogs that have to be seen (I am lucky that all my favorite female guests are qualified except for a little smaller skeleton).
4- Large kennels may not be able to avoid the problem of genetic diseases, after all, this is the deficiency of Du Binquan species itself; There is nothing special about the after-sale of the big dog kennel. Personally, I suggest you buy a Du Binquan, preferably a Du Binquan baby raised by others in the same city. There is no special reason, but I feel that the family is taken care of more than the kennel. However, when choosing, you should pay attention to asking the owner about the baby's parents, and only choose what you like, preferably your own.
Replicated genetic disease data (Baidu Encyclopedia):
Hereditary hip joint disease
Many Du Binquan's natural constitutions are prone to diseases, and they often have hereditary deformities, such as hip dysplasia. This disease is common in many breeds of dogs and belongs to congenital genetic disease. Even if Du Binquan is a frequent visitor to hip joint disease, it is generally believed that this disease is caused by the epidemic and excessive reproduction of this breed of dog. But the so-called susceptibility to this disease does not mean that he will definitely get sick, as long as every owner can determine whether the hip joints of his parents' dogs and grandparents' dogs are normal when buying puppies. You can avoid genetic misfortune. Dogs with hip joint disease are normal at birth, and the disease usually occurs 24 months ago. Because of the developmental disorder of hip joint, it will cause pain, become arthritis, hinder the performance of working dogs, have a bad influence on the pace of the court, and even become an unhappy and inactive pet dog.
Now it is known that Du Binquan has several acquired factors that are easy to cause hip joint diseases, including its body shape, structure, growth mode, calorie intake, electrolyte balance in dog food and so on. If you want to reduce the probability of puppies suffering from this disease, I suggest that you start with controlling the growing environment of puppies, choose dog food with moderate protein content, avoid eating foods with high nutritional units and high calories, eat as few meals as possible, and avoid taking in extra nutrients. In particular, it contains calcium, phosphorus and vitamin D. In addition, it is better to control the puppy's movement mode with a leash than to let it run and jump freely, because unlimited exercise may hurt the developing joints.
According to the latest report of American Animal Plastic Foundation 1995, the proportion of X-ray films of Du Bin's total hip joint lesions has been below 7%, which is 60% lower than before, indicating that breeders have effectively screened breeding dogs. When you buy Du Binquan puppies, it will be more secure if you can obtain relevant OFA, GDC and international inspection registration certificates. If you are unfortunately found to have this disease, don't let it breed again, so as not to pass it on to the next generation.
Another hereditary deformity is elbow dysplasia. Test the registration number of normal elbow dogs over 24 months. Elbow joint abnormalities can be divided into I-III grades, and Grade III elbow joint abnormalities belong to completely degenerative joint diseases. Dogs with normal elbow joints over 24 months old will be issued a registration number and report to the breeding club regularly. In addition, the Center for the Prevention and Control of Genetic Diseases also maintains a comprehensive screening of animals with elbow joint diseases, and issues registration certificates to dogs with normal elbow joints 12 months or more. Only dogs with normal elbow joints can be used for breeding.
Many dogs have myocardial diseases.
For people who breed Dubinquan, the disease they are most worried about is cardiomyopathy. There are more and more dogs suffering from this kind of heart disease. There are two main reasons, one is myocardial dilatation, and the other is myocardial hypertrophy. Du Binquan often has myocardial dilatation. The sick dog's heart is weak because of excessive inflation, just like an inflated balloon, it can't beat effectively and normally, which will eventually lead to heart failure. It is understood that Du Binquan is not only the dog breed with the highest prevalence rate of this disease, but also its prevalence rate is even higher than that of other dog breeds combined, so myocardial dilatation can be said to be the number one killer in Du Binquan. When Du Binquan suffers from cardiomyopathy, it is not easy to detect its abnormality in the early stage, and the owner will not go to the vet until heart failure. Although the etiology of myocardial disease is considered to be closely related to its heredity, there is still a lack of long-term research reports. Some veterinarians believe that the disease is related to the nutritional mechanism, and supplementing amino acids may help prevent it.
Once a dog gets sick, it may have symptoms such as depression, cough, inability to exercise, difficulty breathing, weakness, loss of appetite and even fainting. In particular, Du Bin's sudden death was mostly due to his cardiomyopathy. In order to prevent Du Bin from dying of cardiomyopathy, I suggest that you have a heart examination for your dog regularly, especially for young and middle-aged dogs. It can be effectively detected by X-ray, ultrasound, electrocardiogram and other means, but this disease can be said to be incurable and can only be treated with some drugs that strengthen heart function. If it can't be effectively prevented, only puppies with medical history can be killed. Many cases should be followed up for at least three generations. It is understood that the American Dobbin Springs Club has a research plan, and they want to use DNA testing to test the relationship between this disease and heredity. If this study is successful, disease-free dog breeds can be screened through testing, thus preventing the inheritance of diseases.
Another common disease of Du Binquan is gastric volvulus and intestinal kink. Gastric volvulus means that the dog's stomach is full of air. After exercise, if the dog wolfs down food and water, or is in a state of tension, it will swallow a lot of air, causing stomach torsion, and elderly dogs with sensitive stomach are more likely to get this disease. Dubinquan is the first disease, and it is usually considered as the most susceptible disease to gastric volvulus. It has been reported recently that some deep-breasted dogs, such as Great Dane, Saint Bernard and Boxer, are also susceptible to this disease.
Dogs with twisted stomachs will feel uncomfortable and will be life-threatening. When the stomach is filled with air, just like an inflated balloon will distort, it will hinder the delivery of blood and the digestion of food in the stomach, and even hinder the blood circulation supply needed by the stomach and other digestive organs. Gastric volvulus will aggravate flatulence, release toxins into blood vessels, cause tissue ischemia and lead to death. As soon as the disease starts, it will kill people in four to six hours. Even after being treated by a doctor, one-third of the dogs will still die after the onset.
Although gastrointestinal kink cannot be completely prevented, some simple measures can be taken to reduce the risk of this disease. Don't give Du Binquan a lot of food at ordinary times, let him eat at any time. Instead, he should divide his daily food into three meals: breakfast, lunch and dinner. Don't give him a chance to gobble it up. Better add some chewing to his food? Dry feed should be mixed with a little water to provide it with clean drinking water at any time, but no drinking water is provided when eating three meals. Don't let the dog do strenuous exercise within one hour before and after meals. According to the above practice, it is very likely to save the dog's life, because the owner accidentally caused the dog's stomach to twist and die. However, many dogs abroad, especially large working dogs, suddenly died after training and were sent to the hospital for surgery, only to find that it was gastric volvulus.
Licking the skin is not suitable for reproduction.
A common dermatitis in Du Binquan is licking dermatitis, which even the veterinarian can't do. Before the owner came to find out, Du Binquan may have been licking the skin of a certain point on his foot, revealing his flesh. Why is he licking himself like this? The reason is not clear. Although there are many theories, we are not sure which is the real reason. It is understood that recent studies have pointed out that it is caused by the incomplete development of some nervous systems in dogs. Another theory holds that this disease is the result of an impulsive behavioral response. In Dubinquan, which suffers from licking dermatitis, male dogs are about twice as many as female dogs. We must be very careful when diagnosing these sick dogs, because some sick dogs may be caused by other diseases and usually need biopsy, bacterial culture and even X-ray examination. Du Binquan, whose parents' dogs and siblings' dogs suffer from this disease, can no longer be used as breeding dogs.
Shake your head, you can't prevent it
Du Binquan also has a disease that mainly affects dogs called shaking syndrome, which is caused by cervical instability. When cervical vertebra bone disease occurs, compressing the cervical nerve will cause severe headache, which may lead to the stiffness of the front foot of the dog, such as the Great Dane and other breeds of dogs. This disease often occurs in dogs aged three to eighteen months, but Du Binquan usually develops at the age of four to ten.
According to the latest research, the etiology of the disease is related to genetic factors, overeating and calcium overload. X-rays can be used to diagnose this disease, and special staining methods can be used to outline the damage. To prevent this disease, we should avoid supplementing calcium, eat less and eat more meals, and don't buy offspring dogs with this disease for our family. Due to the late onset of Du Binquan, breeders can't know the condition in advance and can't eliminate and prevent it. It may take several births to get sick.
Thyroid deficiency must be eliminated.
Thyroid insufficiency is Du Binquan's most common endocrine disease. This disease is caused by insufficient secretion of thyroxine, which is caused by many reasons. Among them, lymphothyroiditis is the most common. Dogs usually get sick when they are one to three years old, but they may not see a doctor until their later years, because thyroid hormone will affect heart function, and Du Binquan has a strong tolerance for cardiomyopathy, so it is necessary to supplement thyroid hormone to sick dogs in time, and don't treat sick dogs as breeding dogs.
