If you notice any of the other symptoms of seizure activity immediately following the behavior, even if it is the symptoms of a petit mal seizure
, should be reported to your vet. If the dog
displays no other symptoms of seizure
activity either before or after the fly-catching episode, then chances are it is a doggie OCD, or obsessive-compulsive disorder.
Obsessive--compulsive disorders in dogs are not at all uncommon. Some of the will incessantly lick their paws.
