Dermoid Sinus, Dysplasia, Torsion of the stomach a Herpes

Dermoid Sinus

Dermoid (cyst polynoidální, dermal sinus) is an opening in the skin, thin as a thread, or grooves skin into subcutaneous tissue. It occurs mostly in the vicinity of ridge, from the top of the head to the base of the tail. It can be variously deep recesses of inconspicuous to dermoid extending through the vertebrae of the spine to the spinal cord.

Arises in the embryonic period due to developmental anomalies which result to separate skin completely from the rest of the fabric fabric. In the ectoderm (the layer that becomes the skin) occur rope, compacted tissue, forming narrow channels niťovité leading up to the spine, dura mater or the connective tissue under the skin. Channel looks like a microscopic funnel. This funnel is formed with the hair and skin also contains pores, sweat and sebaceous glands. The canal can also get dandruff, sebum, hair and looking dust. This over time can develop cancer, which can be very painful, it is difficult to heal and can become life-threatening.

Puppy with dermoid already born. There are two variants of dermoid, Leaded and without outlet to the skin surface. Closed variant that does not exit the skin at birth is very difficult recognizable and can therefore occur only at the age of several weeks or months. Dermoid sinus never disappear, but it can be surgically removed without any side effects. It is a hereditary disease and puppies with dermoid is excluded from breeding.



Hip dysplasia is an inherited disorder that in its more severe forms can cause crippling, paralysis, arthritis or painful joints. It is caused by a combination of genetic and environmental factors. It occurs in many species (relatively rare in humans), but most suffer from dogs, especially large breeds with heavy boned and powerful body composition. Among the most endangered breeds is St. Bernard, Newfoundland, Bullmastiff, Bobtail, Bernese Mountain Dog, Dog, Rotwailer, English and Irish Setter, Gordonsetr, Golden Retriever, German Shepherd, Rhodesian Ridgeback, etc.

Hip dysplasia in 89% of cases affect both hips.

Dysplasia of the hip joint is one of the most studied and most common diseases of dogs unambiguous cause hip arthritis.

Dogs showing signs of stiffness or pain when getting up, reluctance to exercise, hopping or other abnormal gait (while running the legs move simultaneously rather than alternately), lameness, pain, reluctance to stand on rear, jump and climb stairs, disloktaci hip or wasting of muscles in the hip area. Radiographs confirmed the presence of dysplasia, but some dogs, this disorder to two years in the X-ray invisible. In addition, many affected dogs shows clinical symptoms, while some are felt sooner than seven months, while others later in adulthood.

Classic diagnostic procedure uses x-rays and test scoring hips. Is performed in accordance with the age and it is recommended to repeat even in adulthood (when the test is done too early, the results are inconclusive). Because dysplasia is largely hereditary, it is recommended to check the degree of dysplasia in the parents before buying a puppy and also when assessing the suitability of the dog for breeding. But although the disorder is hereditary, it can also occur in dogs whose parents have a negative grade dysplasia.


Torsion of the stomach

Torsion of the stomach is the second leading cause of death of dogs after cancer. The disease primarily affects older dogs (approximately 5 years), medium and large breeds with deep ribs and flaccid tissues. Torsion of the stomach, or the Flip, is closely associated with feeding. For dogs that are fed only once a day, the risk of an outbreak of a much larger than males, who have a daily feed ration divided into two or more doses. Also, the variety of food plays a certain role. A study conducted by the Irish Setter has shown that dogs who receive only one type of food, are at much higher risk of gastric torsion than dogs who receive various feeds.

If you are diagnosed with stomach torsion, you must immediately contact your veterinarian and perform surgery. This, however, is often impossible due to the state of the affected animal and therefore often the dog died. Mortality is extremely high. Approximately half of the dogs die before the treatment is not nearly quarter and dies in the first seven days after diagnosis. The statistics is known that 60% of all cases occur during the night.

The exact cause of torsion of the stomach has not yet been clearly elucidated. It is considered that the impact on her stomach distension due to the large amount of food intake and also flaccid tissues in old age, the development of gas in the stomach with subsequent overturning or excessive movement also after meals and the subsequent reversal of an oscillating stomach.


Therefore, it is recommended to treat the dog fed calm up 30 to 50 minutes.



Condition where the breed something incredible begins to happen, despite all common hygienic measures, identify breeders who have had several years and often very successful past. Nezabřezávání bitches malopocetne litters of puppies and early death has become for many of the successful literally a nightmare. What happened? What went wrong?. Among today's incriminated infertility in breeding dogs are often the herpes virus. It is very often the cause of death in the neonatal period, has been known for many years, but now this virus is also often responsible for infertility (females nezabřeznou, although everything seems normal or have unusually small litters of puppies or below average weight).

Special features and epidemiology

This virus was first described in 1965 in the U.S. as an infectious cause of death in newborn puppies. Since then, it is clearly evident that the herpes virus can also cause infection in older puppies and adult animals. It is a specific virus occurring in dogs and other canids. Although it may also apply to other breeding animals, there are signs of illness more frequently in breeding dogs. It's all about the situation, if it's more dogs together (eg exhibitions). The main symptom of this virus infection is lifelong and hidden infection. In other words, once individuals remain infected for life and constant carrier of the virus without visible symptoms nemoci.Ve stressful situations can then be reactivated and the associated viral shedding.


In an adult dog are the consequences of herpes virus infections rarely known. Diagnosed symptoms such as runny nose, disappear after a few days. However, in this way the virus is transmitted as relocated to the mucosa in the respiratory tract. Likewise situated in the genital tract and can cause the formation of small blisters in front of the genital area in females, or the prepuce in dogs. So the virus can be eliminated with the saliva, secretions from the nose, but also from the genitals. Infection that primarily presents no disease occurs by direct contact, such as when licking or coverage. Bitch may be the very first contact with the infected dog. When females infected with coverage or during pregnancy, even though the infection themselves mostly good. However, the virus becomes dangerous for puppies. In early pregnancy can lead to resorption of primary infection (absorption) or after an abortion 35.dnu fruits. However most puppies are infected in the first week of life. If the hidden infection reactivates during stress at birth may become infected during childbirth or shortly after. During childbirth may infect puppies in the birth canal, then on through secretions from the nose and mouth bitch secreted at constant licking and thanks to this close contact, it further transmission of the virus. Thus, the infection rapidly expanding.


If puppies are infected during birth or immediately after, the incubation period is approximately 3-7 days. Among the first symptoms are diarrhea and vomiting. Puppies that from the beginning seem chipper, refusing to suckle for a short time, are listless, suffering from shortness of breath and emit continuously painful screams. These permanent pain symptoms mean to bitch considerable nervous stress. Unsuccessful attempt to calm crying puppies and inability to remove the cause of pain may lead to the fact that their female care ends. This puppies are only slight disease course even more at risk, although they have a chance of survival. You have to calm dogs absolutely necessarily impress breeder. If you get sick all the puppies in the litter, mortality is nearly 100%. Younger individuals will die in most cases within 24 to 48 hours after the onset of symptoms. sick puppies are older, have some hope of survival. Most, however, have lifelong neurological disorder.

Prevention and Care

In order to avoid the breeding risk of infection, it is better to pregnant females in late gestation (approximately 3 weeks before delivery) and puppies with their mother during the first three weeks of isolation. Because the animals are infected with both sexes throughout life, a breeding individuals with positive risk (covering the transmission of the virus). if a female has a high proportion of antibodies, it may at the same time with the breast milk and pass on to their puppies litter is thus protected against the disease.


Herpes virus in dogs is widespread and worldwide cases and the consequences can be a complicated document. Virus, it seems, brings to breed mainly large problems due to potential effects on reproduction. Acute signs (abortion, mortality etc ...) are well known, its role in infertility but still underestimated. CHV infection is everywhere in Europe AIU we are very extended. Due to ignorance of things (unfortunately often by veterinarians), many neonatal deaths postponed (no test for CHV) as a normal mortality rate among carnivorous animals and many chronically nezabřezávajících bitches is not never been tested for the presence of virus.

The presence of the virus itself is from a live animal can not even find in the Czech Republic or in Western Europe. Can be examined only individual blood for antibodies against CHV with the assumption that if the dog survived viral infection, the body will create antibodies. Examination of breeding females before mating is entirely irrelevant since it may be contaminated with coverage or anytime thereafter.

Vir is a portable all body fluids. In neonates therapy is ineffective, because the disease is very rapid. For milder may be attempted to apply intaperitoneálně 1-2 ml serum, from mothers vaccinated or demonstrably positive. Puppies are unable to the age of about 2 weeks enough to keep its temperature and because the virus thrives při35-36 ° C it is possible to influence the course of the disease mainly by increasing the environmental temperature for at least 36-37,7 at 45-55% moisture. Due to fatal consequences in case of infection in the neonatal stage and the first month after birth and complete inability to prevent neonatal mortality is vaccination pregnant bitches Eurican vaccine against herpes 205 cakewalk. The vaccine, which is the only one in the world and is made available to us at the price ranges around 800Kč contains only pure antibodies CHV. Does not, then, as some vaccines against other viral diseases of dogs, modified or attenuated viruses but actually directly antibodies against the virus - it is the active immunization of dogs and the unborn puppies. In the event that, for this step is needed to decide to apply the first dose week before the cover or later than one week after. Proved to be the most suitable vaccine to vaccinate the second day after mating (when one is certain that there is a connection dogs). Second vaccine is then needed one to two weeks before the expected date of confinement. The first dose you prevent mortality of embryos (the notoriously nezabřezávající females), then the second dose immunizes puppies directly.

It is up to each farmer to decide on the right solution. I know a vet who absolutely refused to forcefully vaccinate female, with the pregnant female should not even be let alone deworming vaccinated. To a certain extent, he's right, but he is not a breeder, which will hold in my arms crying puppies and utter powerlessness to watch them die ....
