Encephalitis is the medical term for a swelling of the brain. This, in turn, causes seizures, lethargy and loss of muscle control. This is a neurological disorder, which is the leading cause of death for the Pug breed. (See: Life Span)
This most often strikes Pugs that are between the ages of 2 and 3 years old.
This disease presents itself in 1 of 2 forms: Slow progressive and rapid progressive.
When a Pug dog is having a seizure, he may look into space, circle around and around, stumble, breath very hard, seem confused, be very weak and in some cases, fall to the ground.
If you suspect that your dog is having a seizure, this should be diagnosed by your dog’s vet right away. Anti-seizure mediation may be used and surgery may need to be performed to control possible swelling of the brain.
