BREAKING SCENTS -- Breaking scents help stop dogs from trailing unwanted game. Keep a piece of scent-soaked cloth, sponge, or a scent pad attached to the dog's collar (every day for as long as necessary) until desired results are achieved. Another approach is to use the breaking scent BEFORE the dog develops an interest in unwanted game, especially in areas where game (such as deer) is common.

It depends. Some dogs are not bothered at all by the scent or the spray in the nose. If your hound falls within this group, you are out of luck. Other dogs, actually get used to it and the device becomes obsolete. That said, a found that citronella dog collars were more effective at stopping dog barking than shock collars. So, try one for yourself.
You also need to understand that just putting the collar around your mongrel’s neck will not solve your nuisance barking problem. Without a training program in place, you will find that your pooch still barks when he doesn’t have the citronella dog collar on (canines are smart!) and you can’t have him wearing the collar all the time, since this is not recommended and it is not safe if your pooch is unattended. Additionally, if you have your dog wear the collar for long hours, daily, eventually he will get used to it.
