I have had a lot of dogs and there are certain things I teach them. First, how to tie out. If you move you will have to have a dog on a leash at some point in their life.
Next, I use a plastic bag with empty soda cans to throw at the dog if I see them getting in the trash (never use it if you don’t catch them right away). The puppy needs chew toys and the house puppy proofed until they get threw that stage. If you’re not home confinement is best. Also, I always have a dog door so they can come and go. My dogs are really good and a big part of my life. Good luck.
I’ve had dogs all my life. But this is the first small one in many decades. We have chew toys galore. He uses them, but is always ready to take something left on a night stand, table between chairs, or anywhere he can get to. We’ve essentially taken care of that problem. How he got the phone case is beyond me. I know I saw it on the dresser this morning. Maybe I brushed against it and it fell to the floor. I don’t know.
This home is puppy proofed about as much as can be. All that’s readily available to him are those toys. He doesn’t go after furniture, wood, or anything like that. It’s just the small stuff. And he doesn’t like being outside. We’ll take him out (beyond the normal duty runs) and within 5 minutes he wants back inside. But we can’t let him out of our sight. No way, no how.
