Petguard? Yeah, I had my doubts. The system is just a little lock that keeps the automatic opening lid closed. The whole cover has no means of staying on, so all a dog has to do is knock the entire garbage can over. I had hoped that the deodorizer part would make it so that my dog wouldn't smell anything in the trash that would entice him. Nope. He knocked the whole thing over as predicted. It does look better than a normal can but the Petguard part is a joke...Luckily he didn't break it. I will continue locking my garbage can in the bathroom when I leave the house. Fine looking garbage can, and the automatic part works, but it did not fix my dog problem.
