Like YT says
"buy the breeder, before you buy the puppy".
I read here on YT several "breeders" lurk on sites like YT looking to scam ppl. that's why they joined, because ppl see they are a member they "assume" they must be honest breeders, not always.
It's good that you research every bit of info. you can find.
If you are comfortable with the breeder you selected Good Luck with your soon to be puppy.
BTW, I miss you, I still remember the "saddle shoes" lol
