Tonight at Petco I returned the Fooey bitter spray because it did not work and instead purchased Bitter Yuck at the rave reviews from the employees there. With renewed enthusiasm I applied this to my dog's paws. She is a chronic licker. A few minutes later I saw her licking very close to where Bitter Yuck was applied. So, I poured the contents of Bitter Yuck in a glass. My husband held the glass still while I dipped her dainty little paws in it one by one. She had a smile on her face as I did so. 3 inches of each paw was thoroughly soaked. About 10 minutes later there she was licking with renewed enthusiasm as I've never seen her lick before. The zeal with which she licked indicated to me that I gave her a new element of interest in her daily licking routine. She looked up at me, smiled with appreciation and bowed her head to lick harder than she ever has.So much for Bitter Yuck...
