My pup leo is getting really rough with my other two dogs,biting the dogs legs,and taking toys off them every time they have one,even though we have quite a few chew ropes and squeakers,i dont know if this behaviour is just puppy behaviour,he has been nipped twice off my other dogs,he pushes himself on them all the time,hes also started to jump up at peoples faces children too,which worries me,I am taking him to puppy training soon,i hope they can sort him out,regards sue
