Hi, everyone. My dog continues to bark sporadically throughout the night. I’ve given him water, food, I always leave him to do his business outside before it’s time for him to come inside and go to sleep, but he continues to bark. I’ve even left him some toys to bite on and play with during the night, but he still barks. I want to know what exactly a Citronella collar does to make the dog stop barking. I’m not into striking the dog to make him stop barking so don’t suggest it.
Thank you.
