Congratulations on the new puppy coming!
I know what you mean about a long time since having a puppy. When we got our most recent one, summer of 2019, it had been 14 years since we had a puppy in the house, and 19 years since we'd had a puppy WITHOUT AN ADULT DOG TO HELP!
Anyway: Here's a link to a 2020 thread that might be helpful until more people chime in.
Enjoy and good luck!
