Reprimand your dog in person to avoid digging into the trash can

You can keep an eye on it, and once you find it approaching the trash can, scold it loudly to make it leave voluntarily.

If it doesn't leave, hit it hard a few times when it bites the garbage. Just hit it with moderate force, but don't hit it hard enough to kill it, otherwise it will make it anxious and it may bite. At the same time, you should scold loudly to make it realize that this is wrong.

Spray something with a pungent odor on the edge of the trash can

You can spray some air freshener on the edge of the trash can, or apply some wind oil or cooling oil, but never spray toxic insecticides agent or disinfectant.

Or put the trash can out of reach. Puppies are always curious. When no one is home, you can give it some toys or dog chews to distract its attention.

Daily consumption of dogs’ energy

If they just want more attention before going through the trash can, then we can spend more time with them and play games with them, so that They don't feel too lonely.

But if it is just for fun, then you must stop it in time and scold them to let them know that they cannot do it again, otherwise they may be severely punished.
