Nope, NO, Nada, never ever. If shock collars were effective as some claim they are, they would be used on grade school children too. That right there tells me it is nothing but pure cruelty & abuse. The lazy way with out concern for the dog. If you are incapable, unable, ignorant, & won't train your dog the traditional way, you should not have a dog.
Dogs are a LOT smarter than most people give them credit for. Children in grade school & dogs both learn in the exact same way. Repetition, repetition, repetition, repetition again & again & again. Also the way college students learn or cram for exams. Repetition ...... teaching & training is easy. Using electricity to train a dog or child is completely out of the question.
