Disclosure: I received this in exchange for my honest review.
Are you looking for something for the ultimate dog lover in your family? Or for the fur-baby in your household? If so I would highly recommend the Bark Collar by Our K9. The vibration collar is designed to give eight different corrections in order to reduce the amount of barking that your dog does. This is ideal for those of us whom work during the day and have no idea what our dogs are really up to. Or for those looking to find a way to keep them quieter when guests/deliveries arrive. At under 10$ right now savings of over 70$ this is the time to buy this gift before the 3 day sale ends and the price goes up. Below I have my review and the link is above if you want to check it out.
I have barkers, they yep they bark any noise and they are "dog chatting" up a storm. That being said I don't believe in shock collars and I am not home enough to do an extensive whistle based training. As a matter of fact even if I was I highly doubt I have the patience for it. I have two Chi-weenies, one that is a little fatter than the other, but both are on the smaller chi side. The band didn't quite go tight enough to fit like a normal collar would, however it did work extremely effectively. Even with it loose, it served as a dog version of scared straight without ever having to vibrate. I am honestly not even sure how intense the vibration is because the dogs never made it past the initial warning. The "warning" beep scared both my dogs well enough they stayed quiet and wouldn't bark. They would look around as if they were confused as to what just happened. I am not sure if this is just due to the novelty of the beeping sound when they bark or if they aren't use to having any reprimand other than my yelling? I sometimes think that when they bark and I tell them to quiet down they think I am secretly singing with them so they bark louder. The collar however instantly stopped the barking. Since the size at minimum is still something they can take off I will only have the bigger one wear it for as long as he is willing. It's not easy for him to take off which is a bonus, however it's definitely possible.
Let me describe what you actually receive, you get the collar the battery required, two sets of covers of various lengths for vibration pegs. The longer pegs is what I tried and it was still big, but I do have two very small dogs. If you however, have a more persistent barker, I can imagine that it will actually make it to the vibration stage. I never use shock collars on my dogs so I am not sure how effective vibrations will be relative to it, but I am certain it will cause less pain. I personally like the various levels of correction too. I figured my dogs will learn to test this as they will get use to the warning sound, but the gradual increase in correction should at least keep them confused until they realize that I don't want them "singing" every time the doorbell rings. With the ease of up and down buttons you can increase or decrease the vibration strength, so the 8 different settings is expanded and hopefully if you have a less stubborn dog it should work to stop the unnecessary barking.
