Hi, We have a problem with our dogs peeing in the house, They are confined to the utility room by night as they are house dogs and one of them pees on the paper we have laid down but the other guy pees wherever it suits him, We clean the room thoroughly every morning with bleach and water but the smell persists no matter what we with do, If any one has any tips on how to get rid of the smell I would appreciate it, Regards Cumnor.
