Hi Everyone We purchased a puppy this past Saturday and he was on the shy side but not overly shy and he reacted well to my kids. Since we have brought him home he has become even shyer. He is only playful when he is around my other two dogs and he doesn't seem scared of my kids but he is very reluctant to come to my husband and myself. He walks well on a leash when we go for walks but will not come when called. I plan on getting him into an obedience class asap but I worry that his fear will turn into aggression is this a valid fear? Any input will really help!
