Even food with a high sugar content can cause behavior problems, as it can with children.

Before calling your dog trainer to “fix” your dog’s problem, read what these three veterinarians (specializing in three different fields) have to say. Retraining may still be required, but check out your dog’s health first.  Maybe the behavior was caused by thyroid disease, vaccination or medication.  [Note: The highlights below are mine – Jan Rasmusen.]

Typical clinical signs include unprovoked aggression towards other animals and/or people, sudden onset of seizure disorder in adulthood, disorientation, moodiness, erratic temperament, periods of hyperactivity, hypoattentiveness, depression, fearfulness and phobias, anxiety, submissiveness, passivity, compulsiveness, and irritability.
