You either get the dog OBEDIENCE TRAINED or surrender the dog back to where ever you adopted it from, or surrender it to a pit bull rescue group.
DO not "pee" on our collective legs and tell us is is raining (aka the dog is TRAINED). HOGWASH! and BULL-SHI# !!!!!!!!!
Your dog, sees a cat and JUMPS out your OPEN car window and YOU CAN NOT get it to spin around on a dime or come back, immediately. Instead, you put yourself in EXTREME danger of being HIT BY A CAR chasing after SAID DOG =>> at NIGHT, IN TRAFFIC.
And to make matters worse out of anger and fear YOU REPEATED HIT and SMACK the dog after you DO catch it..... TEACHING it not to EVER come to you or let itself get caught (by you).
You are an abusive, immature, thoughtless owner - who has no business owning ANY pet, let alone a CHALLENGING dog who can so easily OUTSMART you. Place the dog ASAP, in a better situation. You are over your head.
