I put it on my dog and after the three warning signals the first shock made her look around but not yelp or show any sign of discomfort. She is a drama queen so I know she’d react dramatically if the collar caused pain. Being that she is a lab and VERY Smart, I might not be using the collar that often anyway! Anyway, love the customer service. Got quick replies to my stupid questions. (I didn’t see the instructions in the box) never had a company so personable, helpful and eager to have a satisfied customer. Wish more companies were like this!I am very satisfied with the product. It is indeed very helpful to stop my dog from barking when I’m out for jogging.
