wow what breed is the dog??? umm what i would do is keep the dog, and for the guy to gain the dogs respect back because the dog might be a little scared about what had happened. 13 isn't that young the kid should understand but for the 7 year old i think that he/she would have a lil. understanding to be careul because her/his daddy ended up in the hospital for that. THe dog should be in a kennel and then when the whole family is home they should just kinda have a family bonding to get back the dog trust and to get things back to normal if it isn't yet
