I like the idea...I love dogs..just not other people’s...I wonder if a little chili peper injected in the paint ball would make the paint taste so bad the dog would remember to give your property wide berth next time??
Either that or what I used when I was working as a termite fumigator when I was much younger was chloropictin an odorous agent used to let people know the house was being fumigated. Either that or I can get some wild animal musk scent, would be interesting to see what effect that has.
I've said the same thing about kids. = D
