Collapse with overheating = emergency. ","definition":"Exercise-Induced Collapse (EIC) is a genetic condition that causes dogs, especially Labrador Retrievers, to suddenly collapse after intense physical activity. It is characterized by hind limb weakness and, in severe cases, complete collapse. ","ursachen":"The scientific basis of EIC is closely linked to genetic factors. The condition is inherited in an autosomal recessive manner, meaning a dog must have two copies of the defective gene to show symptoms. The affected gene is the dynamin-1 (DNM1) gene, which plays a crucial role in the nervous system. It is responsible for synaptic vesicle endocytosis, a process essential for normal nerve function.   \n\nIn dogs with EIC, a mutation in the DNM1 gene leads to a loss of function of this protein, impairing neurons\u2019 ability to respond efficiently to repeated stimulation. This can cause temporary dysfunction of neuromuscular transmission, especially during or after intense physical activity. \n\nThe exact prevalence of EIC is not fully known, but studies show it is relatively common in Labrador Retrievers. Besides Labradors, other breeds can also be affected, though less often. The mutation in the DNM1 gene is the main trigger for this condition, and genetic testing of breeding animals is increasingly seen as an important tool for controlling the spread of the disease within the population.

The first signs are often weakness or uncertainty \/ disorientation in the hind legs, which occurs during or shortly after intense exercise. Affected dogs may stumble, stagger, or suddenly collapse.  \n\nThe collapse itself is usually not painful, and the dogs remain conscious and responsive to stimuli. The symptoms usually subside within 5 to 25 minutes after stopping the activity, as long as the dog can rest. In severe cases, however, the collapse can be life-threatening, especially if the dog does not get immediate rest.  \n\nIt is important to note that not all dogs with the DNM1 gene mutation show symptoms. The severity of symptoms can vary from dog to dog, and some may live their entire lives without obvious problems, while others experience regular collapse episodes. ","zusammenfassung":"Exercise-Induced Collapse (EIC) is a genetically caused condition in dogs that mainly affects Labrador Retrievers. It is caused by a mutation in the dynamin-1 (DNM1) gene, which is important for normal nervous system function. The disease is inherited in an autosomal recessive manner, meaning dogs must have two copies of the defective gene to show symptoms. These symptoms include Muscle weakness and inability to move after intense physical activity, with dogs often recovering within 20 minutes. Seizures can also occur rarely. A definitive diagnosis can be made with a genetic test that detects the presence of the DNM1 mutation. There is no cure for EIC, but symptoms can be controlled by managing physical activity. Intense exertion should be avoided, and if a collapse occurs, dogs should be cooled immediately and kept calm. The prognosis depends on the owner\u2019s ability to monitor activity; many dogs can still live a normal life. Prevention is done through genetic testing in breeding to minimize passing on the mutation. Owners of dogs at risk of EIC should closely monitor their dog\u2019s activity to reduce the risk of collapse, and regular veterinary check-ups are recommended.          ","diagnose":"The diagnosis of EIC is based primarily on the clinical medical history and the characteristic symptoms. A veterinarian will ask about the type of symptoms, when they occur in connection with physical activity, and the dog\u2019s genetic background. \n\nA definitive diagnosis can be made with a genetic test that checks for the presence of the specific mutation in the DNM1 gene. This test is simple and not invasive, as it typically requires a blood sample or a cheek swab. \n\nOther diagnostic tests may be performed to rule out other possible causes of collapse, such as cardiovascular disease, metabolic disorders, or neurological problems. These may include blood tests, an ECG, X-rays, or an MRI. ","behandlung":"There is no cure for EIC, but the symptoms can be controlled by managing the dog's physical activity. The main treatment is to avoid intense physical exertion that could trigger a collapse. \n\nOwners of dogs with EIC should watch for signs of lethargy or weakness and stop training immediately to prevent a complete collapse. In some cases, short, controlled exercise sessions under close supervision can be helpful to maintain the dog's fitness without provoking symptoms. \n\nIn emergencies, if a dog collapses, it should be moved into the shade immediately and cooled, e.g., by spraying with water. It is important to keep the dog calm and give it time to recover. ","prognose":"The prognosis for dogs with EIC varies depending on the severity of the symptoms and the owner\u2019s ability to manage the dog\u2019s physical activity. Many dogs can live a normal, happy life if episodes are prevented with appropriate measures. \n\nHowever, some dogs are at risk of life-threatening collapse, especially if they exert themselves intensely unsupervised. Therefore, it is crucial that owners are aware of the condition and take appropriate precautions. ","ausblick_auf_aktuelle_forschung":"","zusatzlicher_inhalt_im_hauptteil":"Because EIC is genetic, the key to prevention lies in genetic control within breeding populations. Targeted breeding strategies based on genetic tests can reduce the risk of passing the mutation on to future generations. \n\nBreeders should have potential breeding dogs tested for the DNM1 mutation and consider the results when selecting mating partners. The goal is to minimize the spread of the mutation in the population by not using carriers and affected animals for breeding. \n\nFor owners of dogs with known EIC risk, it is advisable to monitor the dog's physical activity and adjust it if necessary to minimize the risk of collapse. Regular veterinary check-ups and working with a veterinarian can also help ensure the dog's well-being. ","haufig_gestellte_fragen_faqs":"","literaturangaben":"","symptome_ausgeblendet":"","erganzungen":"","faq":[{"frage":"1. What is Exercise-Induced Collapse (EIC) in Labradors?","antwort":"EIC is a hereditary neuromuscular disorder in which affected dogs collapse temporarily after intense exercise. The cause is a mutation in the DNM1 gene, encoding the protein dynamin 1, which is required to maintain synaptic transmission during high neural activity. The disease occurs especially in Labrador Retrievers as well as related breeds such as Chesapeake Bay Retriever and Curly Coated Retriever."},{"frage":"2. What symptoms occur during an EIC episode?","antwort":"Typically, the hindquarters collapse after 5 to 20 minutes of intense exercise, often during emotional excitement such as retrieving. Dogs show a swaying, uncoordinated gait, then go down and drag their hind legs. Consciousness is usually preserved, while body temperature may be markedly elevated. After 5 to 25 minutes of rest, most dogs recover completely."},{"frage":"3. How is EIC diagnosed?","antwort":"Definitive diagnosis is by gene testing for the DNM1 mutation. A blood or saliva sample is sent to a laboratory. The test distinguishes homozygous-clear, carrier and homozygous-affected dogs. Only homozygous-affected dogs show clinical signs."},{"frage":"4. Is EIC life-threatening?","antwort":"Most EIC episodes are harmless and resolve with brief rest. However, deaths during or shortly after collapse have been reported in rare severe cases, mostly from extreme overheating or cardiovascular failure. Intense exercise in hot weather should therefore be strictly avoided."},{"frage":"5. How is EIC treated?","antwort":"There is no curative therapy. Management consists of avoiding triggers, particularly intense retrieving in excitement, prolonged scent work or sprint training. Moderate exercise is usually well tolerated. During an episode, the dog should be placed in a cool, calm environment and, if necessary, cooled with water."},{"frage":"6. Can EIC dogs lead a normal life?","antwort":"Yes, with adapted exercise most dogs lead a largely normal life with good life expectancy. They are well suited as family dogs or in disciplines with moderate activity. They are generally not suitable for hunting work, advanced retrieving competitions or sports requiring intense sprint exercise."},{"frage":"7. How is EIC inherited?","antwort":"Inheritance is autosomal recessive. A dog only shows symptoms when the mutation is inherited from both parents. Carriers with one mutated copy are clinically unaffected but pass the mutation to offspring. In some Labrador populations, carrier rates exceed 30 percent."},{"frage":"8. Should EIC carriers be used for breeding?","antwort":"Mating two carriers must be strictly avoided, as statistically a quarter of the puppies would be affected. Carrier \u00d7 clear matings are acceptable from a breeding perspective if genetic diversity is to be preserved. Gene testing of both parents should be performed before any mating decision."},{"frage":"9. How does EIC differ from heat stroke?","antwort":"Heat stroke involves massively elevated body temperature above 41 \u00b0C, severe panting, rapid pulse and often clouded consciousness, and can affect any dog. EIC dogs show more normal breathing and remain conscious but collapse at the hindquarters. Gene testing clarifies any uncertainty."},{"frage":"10. What role does body temperature play in EIC?","antwort":"High ambient temperature and excitement are the main triggers. Core body temperature in affected dogs often rises more under exercise than in healthy dogs. Training in the cool morning or evening hours, short sessions and adequate cool-down periods substantially reduce the risk of an episode."}],"faq_html":null},"yoast_head":"<!-- This site is optimized with the Yoast SEO Premium plugin v28.1 (Yoast SEO v28.1) - https:\/\/yoast.com\/product\/yoast-seo-premium-wordpress\/ -->\n<title>Collapse Triggered by Exercise in Dogs (Exercise-Induced Collapse, EIC) in dogs<\/title>\n<meta name=\"description\" content=\"Exercise-Induced Collapse (EIC) in Labradors is a genetically caused condition.
