mountain lion! then mix 1 cup of rubbing alcohol 1 tsp of lemongrass oil lace in spray bottle and spray areas you want dog to stay away from. if you spray the hallway enterance, he wont go in it. spray at nose level and a tad on the floor.spray the couch areas.....anywhere you want them to avoid.OR..take a q-tip and daub areas lightly. if there is a doorway you want him to avoid....you can daub a green plastic bag with the lemongrass( drag q-tip wet in circles on the green bag) and spread it out on the floor, once he goes near it he wont like the strong smell and wont sit around it.lay the plastic bag ( DAUBED WITH LEMONGRASS)outside your room...he will not come back to the door BUT DONT DAUB IT TOO MUCH.....this stuff is potent jean
