Correct to protect

Just saw an advert on telly for correct to protect, a company that sells dogs that are trained to attack on command. Security for your family, or just a cute killer pooch. I'm not kidding. They are selling dogs trained to kill as a nice family pet. Can anyone see this going wrong? Little Tommy goes missing,  Rage your new security dog is waddling around, suddenly fat, woofs and Tommy's retainer falls out. I think the only reason that this homicide on 4 legs business exists is because someone rhymed correct and protect. Its Xmas, buy a correct to protect doggie for your local health insurance provider. Train it to attack on the phrase " Denied. Pre-existing condition."
