If you have problems with a puppy chewing things up, this stuff is a life saver. My sweet, innocent, little Daisy likes to chew on things from time to time. She shows a special interest in power cords, mechanical pencils, earbuds and a few other strange items. After spraying the Bitter YUCK! on stuff, she leaves it alone. I just sprayed a ton of it on the Christmas tree. I put it all the way around the tree and up as high as she could possibly reach. I'm also going to give the lights and ornaments a good coating before I put them on the tree. I just wanted to share my finding of this miracle spray with others.
