TYPES OF DOG SEIZURES
By Tess Thompson
What triggers canine or feline seizures
is not exactly known but the general observation is that seizures usually happen
when animals are excited. This excitement may increase during play or a cue
that signifies that play is about to begin. It is also not uncommon for dogs to
have seizures during sleep; however, this should not be confused with barking
and shaking while sleep. A dog may bark or shake in his sleep if he is
dreaming. But if the dog is having a real seizure, he is not likely to be
awakened.
Seizures are classified
according to their severity and duration as mild, moderate, clustered and
severe.
-
Mild or Petit
Mal
o
Momentary seizure with symptoms limited to blank
stares or upward eye movements.
-
Moderate or
Grand Mal
o
This is characterized by the dog falling down, loss
of consciousness and rigidity in the legs. Grand mal normally lasts for one to
three minutes, followed by a period of restlessness, running around and bumping
into objects.
-
Status
Epilepticus
o
The severest type of seizure that lasts for ten
minutes or more at a time or as a series of continuous seizures in a short time
without regaining consciousness.
-
Cluster
Seizures
o
Multiple seizures within a day, as serious as and
difficult to distinguish from status epilepticus
Seizures are unpredictable
and can occur at any time. Status epilepticus and cluster seizure can
prove to be fatal. Normally the pre-seizure period, known as aura, lasts only
for a few seconds and is not easily noticeable. The dog may appear restless or be
excessively affectionate, whine, wander or hide or snap at the air during the
pre-seizure period.
The actual seizure is known
as ictus, a sudden occurrence, or recurrence of a disease. This period may last
a couple of seconds to several minutes. Depending on the severity of the
attack, the dog experiences involuntary urination or defecation, loss of
control of the limbs, convulsions. In such a state the dog may paddle as if he
is swimming, at times. The post seizure period is marked by confusion, loss of
bladder control, distress and disorientation.
Seeing your dog in a
seizure can be a harrowing experience for owners, especially if it is the first
time. Although the dog himself does not feel any pain, he is in an agonizing
state wherein he has no control over his movements. Even when conscious he is
not likely to be aware of what his going around him.
It is advisable to keep a
distance from the dog and approach him only from behind to gently pat his back.
Do not panic and make sure to note the details of the various symptoms that
appear during the seizure. This will be of great help to the veterinarian and
will aid him in arriving at the type of seizure that has occurred.
Apart from canine and feline epilepsy, any physiological disease that
disturbs the neurological impulses from the brain can also cause seizures. All
types of seizures, even those you are not very sure of should be reported to a
veterinarian. Left untreated, there is a great likelihood of the condition
aggravating and resulting in recurrent and cluster seizures.
