New puppy and expectations?

So we are getting a new baby boy (standard poodle) in just two-ish weeks. I am very excited. I feel like how I did waiting for my own kids to arrive lol. This time last year, we said goodbye to our 12 year old standard poodle, Ivan. He was my soul dog. He was so amazing. So amazing that it makes me nervous for this new guy. Because Ivan was a dang unicorn. The moment we brought him home he was literally perfect. He had literally no puppy traits. He didn’t whine, he didn’t bark, he didn’t chew things, he didn’t nip, he only had 2 accidents inside, he was so easy to train. He was insanely calm, always. So calm, that I actually thought something was wrong with him and had him checked out again at the vet. Nothing wrong, he was just naturally the goodest boi. And he stayed that way his entire life (minus acting like a terrorist outside with a chuck-it ball lol).

I know each dog is different, and the likelihood of us getting that exact same temperament and personality is low. I have talked to the breeder about it and they are monitoring which puppy would suit us best (we have second pick of the 5 that are left). And I do think they will be able to give good input as their dogs are often show dogs as well as service dogs, so they are well versed in looking out for temperament.

But how do you set yourself up for success with a new puppy without having expectations? I’m trying not to assume we’ll have the same easy time as we did with Ivan, but I’d be lying if I don’t have some kind of expectations leaning that way. It’s been 13 years now since we’ve had a puppy, and this time we have 3 little kids and two cats added into the mix making it a lot different than the first time (we still have our toy poodle who we had before we got Ivan). If anyone has any advice or tips on the expectations/getting a new puppy after loss I would GREATLY appreciate it. I have two weeks to get my mind and house together for this.
