I can relate, I was once walking a neighbours dog (I was training her to walk on a halti) through some neighbourhood streets by the big park, when 2 HUGE GSD came storming out of a backyard snarling & snapping & eyeing Sandy (the dog I was walking). Sandy tried to run, but I wouldn't let go, I grabbed her with all my strength, flopped her on my shoulder, screamed & ran for our lives towards the hwy. its pretty scary how much u can lift & how fast u can run when ur scared for ur life... the dog weighed about 70 pounds & I was maybe 5 feet tall & about 12yrs at the time
