What breed of dog did you get after your first dog passed away?

I often wonder what will I do when my dog passes away. I find it hard to believe I would have the heart to adopt another dog after my dog passes. I think I might compare the new dog to the old one too much.
I’ve known people who always adopted a dog after another passes. Some get the same breed and some get a dog that in no way reminds them of their former dog.
My sister adopted a dog that is nothing like her former dog but whenever she sees the breed that reminds her of her first dog she seems happy and then sad.
For those of you who have gotten a different breed, does it make it easier to adopt a different breed or do you think adopting the same breed in the long run eases the pain of loosing the first one?
I even had a cousin who got the same exact type dog (all mutts) and gave them all the same name except added 2 and 3 to the two that came after the first one.
