Scent Off Gel releases an unpleasant smell to prevent pets from fouling in certain areas. Dogs recognise a previously used fouling area by traces of smells from previous visits. Scent Off Gel releases a strong highly perfumed odour over a period of days to confuse the dog's sense of smell and encourage it to move to other untreated areas. The gel can be spread directly onto the area you wish to protect and can be renewed every 5-7 days until the fouling habit has been broken. Children do not need to be kept away for the area after treatment.
