Nope! Not necessary at all. My current 1 1/2 year old was a great pup to potty train. He had one accident inside and I didn't catch him, so he didn't even get corrected. He is wonderfully housebroken.
Consistency is far more important. I would take him to the same spot outside. We would go outside every 15-20 minutes while he was active inside and 15 minutes after a nap or eating/drinking. It was a bit excessive, but he caught on and has never had an accident other than that one time.
