RE: shock collar on a newly pregnant dog, okay or bad?
intensity level is ultra important. I have had extremely hard dogs that had a very low tolerance for electricity and soft dogs that you had to set it on 5 for. Every single dog is different. At the lowest levels of stimulation it is like a tickle and should not have a negative effect. Higher levels and personally I would try alternate means as stated until later. Barking sometimes does take a little more coercion than other tasks. good luck
