I feel like I’m doing everything wrong with my new puppy, how did you get it to stop?

As the title implies, I feel like I’m doing everything wrong for my new pup. We took him home yesterday so this is only night 2 and yet everything I do for him feels so wrong.

I’ve helped raise a puppy before and we had him for 17 years, yet everything that worked before for him doesn’t seem to help my new pup at all?

I know that’s probably a super common thing, or at least I hope. But I just can’t shake this feeling that everything I’m doing to take care of him is the wrong thing.

Maybe it’s the lack of sleep, maybe it’s the nerves, but I have no idea how to get this feeling to stop. What helped you guys?
