Is this a guaranteed way for a dealer to beat a home search by police?

You are a suspected drug dealer, and cops show up at your house with a warrant to search and a canine unit to sniff out and lead the police to contraband.

So first, hide the drugs in a place that the cops will never think to look, unless the drug dog sniffs it out.

For example, there are companies that manufacture hiding places for goods, such as fake wall outlets, fake pipes to put up in utility rooms or crawl spaces, etc.

Police don't consult with plumbers and electricians when they do home searches, and aren't going to take sledgehammers to walls and pipes unless the drug dog leads them straight there specifically.

So what about the drug dog?

Easy.

Just routinely run the baggies and such all over everything in your house.

So here's my question:

What are the cops going to do when their drug dog keeps going crazy at every nook and cranny, giving them false positive after false positive, and the cops haven't personally found anything?
