Possessivness over toys

Question
My Pit bull is an all around good dog, yet I had a problem with him in the past when I had another dog. He was very possessive with her over toys and of course food. So I fed them separately. But he has shown me that he is possessive over toys with my son too. He will not get possessive with me only my son or other animals. I have removed all toys from the area and he is of course fed in a separate room. Yet I am worried that if I slip up by accident something terrible will happen. I love both my son and my dog very much and I try to do what is best for the both of them. Please help, Thank you!

Answer
How old is your son?  With somebody the right age in the family, 4-H dog training is a great idea. In my area, clubs form soon after the first of the year. Even many urban areas have 4-H. For info look in your phone book under government listings for extension or cooperative extension offices. Ask specifically about a dog or canine club. The 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 a treat.

4-H or not, that last site has some good material on dog and children.  The dog must learn to respect your son.
