Causes

• Dog focal seizures are caused by head injury, disease such as hydrocephalus (water on the brain), poisoning, brain tumors or epilepsy.
  
  

Types

• There are two types of partial seizures in dogs--simple focal seizures and complex focal seizures. The difference is that in the complex type, the dog's behavior radically changes.
  
  

Warnings

• According to Hurricane Animal Hospital, some dogs get frightened after a partial seizure. Dogs with complex focal seizure may become suddenly aggressive.
  
  

Time Frame

• Partial seizures in dogs usually last less than one minute. If they last for more than five minutes, call a vet.
  
  

Diagnosis

• Treatment depends entirely upon diagnosing the cause of the dog's focal seizures. Diagnostic tests can involve X-rays, MRIs and blood work. Then it can be decided if drugs or surgery would be appropriate.
