How to get my german shepherd nicer to visit?
I have a 6 month old Shepperd mix mostly Shepperd we adopted him from a rescue shelter he is a sweetheart with my two very active toddler ages three and four .I usually have lots of play dates and have family members with children come over to visit.Since we have gotten him our visit are short and not sweet and I even attempted to have have a sleep over with other children and that didn't go well either we had to keep him in his crate or other room because of his barking and attempts to bit he just recently chased neighbor hood children down the street and attempted to bit them because my daughter got to the front door before I did and let him out. He's not violent with us how do I get him to be friendlier to other people? HELP
