I stumbled across this product while trying to find some candles which would help mask my puppies’ “aroma” … they’re wonderful. While they don’t really have a scent to them (even though they say they do) they do minimize the odor ALOT. As an example, our one puppy just was sick and I lit this in his room to help eliminate the stink left behind. Worked so well! My puppies and I are very thankful, because as anyone with pets knows … that stink after a sick animal will burn your nostrils for days 😩
