A new trash can is a short-term fix. Answer a few quick questions to get a personalized recommendation that actually changes the behavior.

Dogs are scavengers by nature. The trash is not a behavior problem. It is an instinct problem. Locking the lid or buying a heavier can does not change what your dog is driven to do. Worse, a determined dog can knock over a can, crack a plastic lock, or injure themselves on broken edges trying to get in.
The only fix that lasts is one that teaches your dog the trash is off limits. Not one that just makes the trash harder to reach.
Shields® Units by Invisible Fence® Brand creates an invisible boundary around your trash that your dog learns to respect consistently, whether you are home or not.
