We're proud to say that these are the worst products we've ever made. Bitter End products taste so awful - and that's good!  The bitter flavorant is useful for dogs or cats with undesirable licking, biting or chewing habits.  When sprayed on your pet's coat, it is a liquid shield that breaks the lick, bite, itch cycle.  It is useful when an Elizabethan collar is removed after surgeries or treatment for hot spots.
