Footsack is a training aid for dogs and cats — designed as an aid to break pets of undesirable habits indoors (e.g. sleeping on furniture). Since Footsack is merely a repellent spray, it should be accompanied by appropriate training to facilitate behaviour modification. How does it work? Footsack contains an odour that pets find offensive and which will keep them away from areas where you don’t want them to be for up to 12 hours. (Humans do not find the smell offensive.) How do you use it? Spray the furniture, carpet or other area until slightly moist. If you do not wish to spray directly onto sensitive surfaces you can spray a piece of cloth and place on the object or area to be protected. Repeat daily or as often as required to maintain the effect. To break established urination patterns of dogs, it is important to use in conjunction with relevant behaviour modification.
