Basics and possible causes
Seizures in dogs can be triggered by a variety of factors affecting both the central nervous systemThe CNS (central nervous system) consists of the brain and spinal cord. It is responsible for processing information and controls most functions of the body and behavior. and the musculature. One of the most common causes is epilepsy, a neurological disorder that leads to recurrentRecurrent refers to a disease that repeatedly returns or worsens after a temporary remission or improvement. Convulsions. These Convulsions can be focalFocal refers to a limited or specific area. In medicine, this may concern a localized area where a disease or pathological process is active, such as a focal seizure that affects only part of the brain., meaning restricted to one body part, or generalizedGeneralized means that a disease or condition affects a large part of the body or multiple organ systems. Generalized diseases can show systemic symptoms and may require more comprehensive treatment., affecting the entire body.
Another common cause of Seizures is hypoglycemiaHypoglycemia is a condition in which blood sugar levels fall below the normal range. Symptoms may include tremors, sweating, Hunger, confusion, and in severe cases, loss of consciousness., or low blood sugar. This often occurs in small breeds or young puppies who have not consumed enough food. The lack of glucoseGlucose is a simple sugar and the body's main source of energy. The concentration of glucose in the blood is regulated to meet the energy needs of the cells. impairs normal brain function and can lead to Seizures.
Toxins ingested by dogs can also triggerA trigger is a stimulus that elicits a specific reaction or state. In veterinary medicine, this can refer to emotional responses, such as fear or aggression, or medical conditions, such as seizures in dogs and cats. Seizures. These include certain foods like chocolate or xylitol, as well as chemical substances such as pesticidesPesticides are chemical or biological substances used to control pests, including insects, weeds, and fungi. In dogs and cats, exposure to certain pesticides can be harmful to health and lead to signs of poisoning. and fertilizers. These poisons directly affect the nervous system and lead to uncontrolled muscle contractions.
Infections of the central nervous systemThe CNS (central nervous system) consists of the brain and spinal cord. It is responsible for processing information and controls most functions of the body and behavior., such as distemper or meningitis, can also cause Seizures. These diseases lead to inflammation of the brain and surrounding structures, increasing the risk of Convulsions. MetabolicMetabolic refers to metabolism, i.e. the entirety of chemical processes that take place in a living organism to enable life processes. Metabolic disorders can cause a variety of Diseases in Dogs and cats. diseases, such as liver or kidney failureRenal failure is a condition in which the kidneys can no longer adequately perform their function of filtering and excreting waste products from the blood. It can be acute or chronic and requires immediate medical treatment., can also lead to Seizures due to the accumulation of toxins in the body.
Typical accompanying symptoms
- Muscle twitching: Uncontrolled movements of individual muscles or muscle groups that occur suddenly and are often rhythmic.
- Loss of consciousness: In some cases, a dog may lose consciousness during a seizure and not respond to its surroundings.
- Salivation: Increased salivation is often observed during a seizure and may be an indicationIndication refers to a valid reason or rationale for using a specific treatment, medication, or medical procedure. It is based on the diagnosis and the patient's clinical condition. of a neurological disorder.
- Confusion: After a seizure, the dog may appear disoriented or confused and have difficulty moving normally.
- Involuntary urination or defecation: Uncontrolled passage of urine or feces may occur during a seizure.
- Stiff movements: The muscles can stiffen during a seizure, leading to a rigid posture.
When to see a vet?
A veterinarian should definitely be consulted if a dog suffers a seizure, especially if the seizure lasts longer than five minutes or multipleMultiple means manifold or repeated and is used to describe conditions or events that occur in multiple instances or at different locations. In veterinary medicine, this may indicate multiple lesions, tumors, or other pathological changes. seizures occur in a short period of time. Prolonged or repeated seizures can indicate a serious underlying condition that requires urgent treatment.
Even if the dog remains confused for a long time after a seizure or shows signs of pain, a veterinary visit is necessary. Immediate clarification is important to minimize the risk of permanent damage and improve the dog’s quality of life.
Symptom recognition for the pet owner and veterinary diagnostic procedure
For pet owners, it is important to recognize the signs of a seizure to react quickly. Observations such as the duration and frequency of the Convulsions, as well as accompanying symptoms, should be noted to provide the veterinarian with an accurate description. This facilitates DiagnosisA diagnosis is the identification of a disease or condition by its symptoms and/or results from diagnostic tests. It is the first step in the management and treatment of patients. and the selection of appropriate treatment.
The veterinarian will first take a thorough medical historyThe medical history is the systematic collection of a patient's medical history through questioning. It includes information about previous illnesses, treatments, allergies, and lifestyle habits. and perform a physical examination. Blood tests can help rule out metabolicMetabolic refers to metabolism, i.e. the entirety of chemical processes that take place in a living organism to enable life processes. Metabolic disorders can cause a variety of Diseases in Dogs and cats. disorders or infections. In some cases, further examinations such as an EEG (electroencephalogram) or imaging procedures like MRI (magnetic resonance imaging) or CT (computed tomography) are necessary to identify structural problems in the brain.
What the pet owner can do and professional therapy options
As a pet owner, there are some immediate measures that can be taken to improve the dog’s well-being during a seizure. First, the dog should be moved to a safe environment to prevent injuries from furniture or other objects. The room should be kept quiet to reduce stressStress refers to the state of an organism reacting to external stimuli or demands. In veterinary medicine, stress can have physical or psychological effects on animals, impacting their health and well-being..
It is important to remain calm during a seizure and not to touch the dog to avoid the risk of bites or further injuries. After the seizure, the dog should be given time to recover and should be monitored in a quiet environment.
The pet owner should try to note the time and duration of the seizure, as this information is crucial for the veterinary DiagnosisA diagnosis is the identification of a disease or condition by its symptoms and/or results from diagnostic tests. It is the first step in the management and treatment of patients.. In case of repeated Convulsions or signs of complications, a veterinarian should be consulted immediately to ensure appropriate treatment.
Outlook on current research
Research on Seizures in dogs currently focuses on several key areas, including the identification of genetic markers that may influence the occurrence of Seizures. Scientists are investigating the genetic predispositionA predisposition is an innate inclination or susceptibility of an organism to certain diseases or conditions. In dogs and cats, there may be a genetic predisposition to certain conditions such as hip dysplasia or certain heart diseases. of certain breeds to neurological disorders that can lead to Seizures. These studies could enable the development of more targeted therapy approaches in the future.
Another significant branch of research deals with the biochemical and electrical activity in the brains of dogs during a seizure. Researchers use advanced imaging techniques such as functional magnetic resonance imaging (fMRI) and electroencephalography (EEG) to gain a better understanding of the neural networks activated during a seizure. These techniques help to better understand the underlying mechanisms of Seizures and to develop potential therapyTherapy refers to the treatment of diseases or disorders with the aim of alleviating symptoms, promoting healing, or improving quality of life. Therapies can be medicinal, surgical, or through other medical interventions. approaches.
Furthermore, intensive research is being conducted on new medications and therapies that can effectively alleviate Seizures in dogs. In particular, the efficacy and safety of cannabinoids are being investigated in clinical trials. InitialInitial means beginning or at the start. In medicine, it can refer to the first symptoms of a disease or the first phase of a treatment process. results are promising and suggest that cannabinoids can reduce the frequency and severity of Convulsions in some dogs.
An exciting area of research is also the investigation of environmental factors that could triggerA trigger is a stimulus that elicits a specific reaction or state.

These investigations are crucial to understanding the full spectrum of effects of Seizures on canineCanine refers to anything related to dogs. The term is used to describe characteristics, diseases, or specific aspects that specifically affect dogs. well-being and to determine which treatment approaches ensure the best quality of life.
Another important area of research is the development of non-invasive DiagnosisA diagnosis is the identification of a disease or condition by its symptoms and/or results from diagnostic tests. It is the first step in the management and treatment of patients. methods. Currently, many available tests are invasiveInvasive describes medical procedures or pathogens that enter the body or penetrate tissue. In medicine, invasive procedures can range from minimally invasive techniques to open surgery. and can be stressful for the dog. Researchers are working on developing blood tests or saliva tests that target specific biomarkers to enable faster and less burdensome DiagnosisA diagnosis is the identification of a disease or condition by its symptoms and/or results from diagnostic tests. It is the first step in the management and treatment of patients..
In addition, efforts are being made to better understand the role of the immune systemThe immune system is the body's defense system against infectious agents such as bacteria, viruses, fungi, and parasites. It comprises a complex network of organs, cells, and molecules that work together to protect the body. in the development of Seizures in dogs. Some researchers are investigating whether autoimmune reactions or inflammatory processes affect the brain and thus lead to Convulsions. These findings could open up new therapeutic approaches that go beyond currently available treatments.
The research into the long-term effects of anticonvulsantsAnticonvulsants, also called antiepileptic drugs, are medications used to control or prevent seizures. They are used in dogs and cats with epilepsy or other conditions that cause seizures., the medications used to treat Seizures, is also an important aspect of current research. Scientists are investigating the possible long-term side effects of these medications and evaluating their effectiveness in improving the quality of life of dogs.
Finally, there are international collaborations between research institutes and universities that aim to capture the genetic and environmental factors that affect seizures in dogs worldwide. These global studies are crucial to obtaining a comprehensive picture of the possible causes and treatments.
Overall, research into Seizures in dogs shows a dynamic and growing interest in developing new DiagnosisA diagnosis is the identification of a disease or condition by its symptoms and/or results from diagnostic tests.
