I have a five month on Pit Bull Terrier. She is a very submissive dog although I don't want her to be Cujo I do want her to not be scared of every noise she also will not bark at people coming towards the house. My other dog will alert us to anyone coming near the house but the pit bull does not bark and if she does then she will bark then run away. Do not mistake me in no way do I want a dog that scares everyone but I also don't want a dog that may get stolen in the future because she is either to friendly or to scared to alert to strangers in the yard. Please Help Someone!
