Most often, an animal behaving aggressively or acting strangely has a behavioral problem or some other reason for the change in behavior. If, however, these changes occur as discrete episodes, and the pet also has a generalized seizure, we can be sure that this is a complex focal seizure and treat it accordingly. People with complex focal seizures may experience hallucinations. Some dogs have episodes of fly-biting where they appear to be biting at imaginary flies around their head. Some of these may be complex focal seizures although we cannot tell for sure.

Another interesting association which as been increasing in frequency is the link between thyroid dysfunction and aberrant behavior. Typical clinical signs include unprovoked aggression towards other animals and/or people, sudden onset of a seizure disorder in adulthood, disorientation, moodiness, erratic temperament, periods of hyperactivity, hypo-attentiveness, depression, fearfulness and phobias, anxiety, submissiveness, passivity, compulsiveness, and irritability. After the episodes, a majority of the animals were noted to behave as if they were coming out of a trance- like state and were unaware of their previous behavior.
