Don't present a situation for this to happen, keep your dog on leed when required, participate or develop constructive forms of interaction/relaxation. Participate within a formal "obedience environment" if available and enable the dog to exercise where there is no possible chance of him getting into another dog, the dog aggression issue is to be addressed in general as this is not favourable behavior an issue created and worsened due to letting it happen.
