I'm hoping for some guidance here. Emma is just about a year old (June 2nd), and is an absolute love; HOWEVER, she has a habit, only when excited and especially around children (my grandsons included), of jumping, nipping at their clothing, nipping at their hands, and just being very hard to control, especially if the child is running. Today at the park, she did it to a little boy and grabbed his hand - luckily, she didn't hurt him, but I was mortified. Some of the other dog owners suggested that maybe I should try an E-collar, and just try beginning with a "light" vibration/shock, which really upsets me :( Does anyone have any suggestions here? Thanks.
