I couldn't find a newsgroup that would really related to my question so
this group came the closest. I live in a subdivision where many
neighbors have pets(dogs). Everytime i mow the yard some dog**** is
laying in the grass. I can't find any lawn chemicals to discourage dogs
from ****ting in my yard. The alternative is that i heard dogs do not
like high pitch sounds. Is there an audio device that i can attach to
one side of my house from maybe wire it from inside my house to the
exterior of the left side of my house to sound off this device, thus
discouraging dogs from getting on my side yard? Thanks.
