Dogs have an extremely sensitive sense of smell, which can make the kitchen trash an enticing object of interest. Because eating human foods (especially those old, germy human foods that lurk in the trash) can be unhealthy for a dog, it's important that you make sure you put an end to your puppy's "dumpster diving." Sooo many pet parents have this plundering problem, but, in most cases, the civilizing solution is actually really, really simple:
1) Purchase a trash can that has a secure lid.
2) Before you put your liners in, place two old 10lb weights at the bottom of your trash can (so, unless he's been working out), your dog will no longer be able to knock the trash over)
