aggressive yellow bitch

Question
My 2 yr old lab seems to be alright with some people when out walking,yet with others she wants to attack them.It has become very worrying as she is so unpredictable.....Have you any suggestions?

Answer
The key to most behavior problems is approaching things using the dog's natural instincts.  Dogs see all the people and dogs in the household as a pack with each having their own rank in the pack and a top dog.  Life is much easier if the 2 legged pack members outrank the 4 legged ones.  You can learn to play the role of top dog by reading some books or going to a good obedience class. A good obedience class or book is about you being top dog, not about rewarding standard commands with a treat. Start at http://www.dogsbestfriend.com/

One advantage of getting into a good class, is that the instructor can actually see how the dog behaves and help you.  Unfortunately some instructors aren't very good.
