YORKSHIRE TOY MALE

we have a 6 month old yorky male we are having a problem housebreaking him to go potty outside HELP PLEASE IF YOU HAVE ANY IDEAS OR SUGGESTIONS AND KNOWLEDGE WOULD SO LUV TO HEAR FROM U THANKS MUCH ZOIE

This may sound silly, but it has worked for me. When your little guy goes in the house, use paper towel to wipe it up and then anchor the paper towel outside in the spot you want him to go (yard may look funny for a while with towels all over). Apparently, they get the scent from the towel and start to go where you have put them. Hope this helps.
