[dog trainer]

I would wait a while and see if they work it out,If you do use a collar put it on the flank of the dog with the reciever on the belly and when the dog shows aggression give it a mild shock and no words said he will turn to see what got his back side and once he figures out he can't win the fight he will stop trying. Putting it on the neck makes them think they are getting bit and fight harder.
