Ryder my German Shepherd is crazy with his ball. However, when Madison has his ball he has extreme self control.
In my view, Well taken care of GSDs are notoriously good with children. My parents GSD used to “herd” my sisters babies back into the living room when they would try to crawl out. GSDs have excellent self control, even with their food or treats, you could practically put a treat in my parent’s dog’s mouth, remove it and give it back without even grazing a tooth.
