Witnessing a seizure can be an alarming experience for anyone involved, and more often than not, it signals a deeper health issue. As experienced veterinarians, we recognize the distress pet owners feel when their cherished dog experiences a seizure. Here's a comprehensive guide to navigating through a seizure, from managing the episode to following up with veterinary care.
Understanding the Causes of Seizures in Dogs
Seizures in dogs can indicate a variety of underlying conditions, with epilepsy being the most prevalent cause. Environmental chemicals, if consumed, can also trigger seizures. These include, but are not limited to, household cleaning products, garden chemicals, toxic plants, and foods that are harmful to dogs.
Additional causes of seizures include:
- Liver disorders
- Abnormal blood sugar levels
- Kidney disorders
- Electrolyte imbalances
- Anemia
- Traumatic brain injuries
- Encephalitis
- Cerebrovascular accidents (strokes)
- Brain tumors
Identifying Seizure Symptoms in Dogs
Dogs might exhibit confusion, a dazed expression, instability, or gaze into space before experiencing a seizure. They may seek isolation or behave unusually. Post-seizure, dogs might appear disoriented, unsteady, or suffer from temporary blindness.
Common symptoms of a dog seizure include:
- Collapse
- Jerking movements
- Rigidity
- Muscular twitching
- Unconsciousness
- Excessive salivation
- Snapping motions
- Chewing on the tongue
Different Types of Seizures in Dogs
Exploring the varieties of seizures:
Grand mal seizures, the most frequently occurring type, involve widespread abnormal electrical activity in the brain, leading to the observable pre-seizure and seizure behaviors. These seizures typically last from a few seconds to several minutes.
Focal seizures affect specific areas or limbs of the dog, potentially evolving into more generalized seizures. Psychomotor seizures present through unusual behaviors rather than muscular spasms, such as attacking an unseen object, and can be difficult to differentiate from normal dog behaviors unless consistently observed during seizures.
Idiopathic epilepsy refers to seizures of unknown origin, excluding those categorized as grand mal, focal, or psychomotor. These seizures are more prevalent in dogs aged six months to six years, with certain breeds like Border Collies, Australian Shepherds, Labrador Retrievers, Beagles, and German Shepherds being more susceptible.
Emergency Response to Dog Seizures
Maintain your composure. Move your dog away from potential hazards such as furniture or stairways carefully. Avoid their mouth to prevent accidental bites, and do not attempt to insert anything into their mouth. Despite common misconceptions, dogs are not at risk of choking on their tongue. Record the seizure's duration; this information is vital for your vet to diagnose the cause and severity. In cases where the seizure extends beyond a few minutes, cooling measures such as fans and cold compresses on their paws are advisable to prevent overheating. Immediate veterinary attention is required for seizures lasting more than five minutes or multiple seizures without regaining consciousness, as prolonged seizures can lead to overheating, respiratory difficulties, and potential brain damage from insufficient oxygen.
Seizure Management and Treatment
While a single seizure may not be life-threatening, it should not be disregarded, especially if your dog has not been previously diagnosed or treated for seizure disorders. Prompt veterinary care is essential.
A thorough examination, including bloodwork and a physical assessment, will be conducted to identify the seizure's cause. Treatment may include anticonvulsant medication, which, once initiated, is typically required for life.
Although seizures can be distressing, early and proactive treatment significantly improves outcomes. With diligent observation and medication, dogs with epilepsy can enjoy fulfilling lives. Should you suspect a seizure, contact us immediately for diagnosis and to begin appropriate treatment.
