"I have two new dogs (Long Haired Chihuahuas) added to my "pack" of three this past April( Now total of 5 . Brother and sister are a year old. They have growled at my 26 year old son since day one and won't go near him. Other than their behavior with him, they are gentle and loving toward me and anyone else they meet. He says it's the dogs problem; I say it is him. Dogs are a pretty good judge of character. What's your spin on it?"
