My guys can obviously put thier head on my counters. What I do is, I get a soda can, put in pennies, tape it shut well! ( only do this if you are home so they wont chew up the can and eat the pennies) and then I wrap it in a kitchen dirty- the dirtier the better ( ie smells like food) and wrap it on the counter and wait. When the crash goes off- " WHAT IS GOING ON IN HERE.." AS THE guilty party leaves the kitchen in a rush.
As far as trash cans, they sell those door or window notifiers that does an alarm when the connection is broken and can be shut off when you are using it. I just take the lip off so I dont have to turn it on and off- but it sure does stop the trash can raiders. ..
As far as this supplement, I have never tried it, but I know it thins the blood. I wouldnt use it because if there was an accident and the dog had to have surgery, it would be harder to operate with thin blood. There is a plug in that is a calming agent but I forgot the name of it. But it works..
