We bought this means, because it was always peed in our front yard (the dog, not the holder, of which we at least go out) ... unfortunately this means showed no effect. In addition, you can see it clearly on the trails and rocks. It's fine as dust, such as flour and white as snow. Man "powdering" it to the plants to be protected around. One siehts from afar (until it eventually rains again) ... Conclusion: one can dusting prima his front yard White, but has no deterrent effect on dogs (at least not for us), shame
