With my first pit i ensured/trained him that he never jumped out of my car untill told(this by the way is essential training, you may think this isn,t a problem when letting him vault out of car when you are in the middle of a forest but said dog will do the same when you are parked on a busy highway)however i forgot to train him on entering a car on command only.A freind came round to show my wife her newborn bay who was in the back in a child seat.Yup u guessed right …..he vaulted in right on top of child,luckily babe was ok but as our ex freind wasnt a dog lover we hav’nt seen her since.
