Personally, I would say 3-4 is a good gap. That is what we have done with our last 3 pups, I wouldn’t want them to be much farther apart as I feel like they wouldn’t play or bond quite as well when the older one is more set in their ways and has less energy for puppy shenanigans
I don’t know about my favorite ever, but the episode I rewatch and love the most from the last few years is the Jackie Daytona (On the Run) episode of What We Do In The Shadows. It’s just perfection from start to finish. It’s ridiculous, hilarious, it’s endlessly quotable, and it doesn’t matter how many times I have seen it- I will always be up for another rewatch. The show is great in it’s entirety but that episode was just pure gold!
