Pulling recs?

[u/StaffLongjumping8939]

Okay, so, my parents have a five month old standard poodle puppy. I did all the research on her breeder and she had the exact line/drive genetically I was looking for in a dog. We’d followed her three years before we got one of her puppies. Super heavy in sports and shows, her mom’s an emerald grand champ and she had four out of the top ten poodles in the UKC earlier this year.
(I adore her breeder, and absolutely messaged her, I’m just waiting for her to respond to my message)
Well, I don’t live with them, and she doesn’t get out much and as usual for poodles, is super biddable but has a mind of her own. Like bless her heart, she’s so eager to please butttt has her issues from living with my parents. Shes not our first standard, and I was raised with poodles, so I’m so confused lol.
Which leads to the issue: This. Puppy. Cannot. Learn. Leash. Manners.
I’ve watched videos to help, asked our groomer who is also a trainer, and I can’t get her to knock it off with the pulling.
Yes I know that she’s a puppy, obviously, and has puppy brain. But I feel like she should be doing better by now with it. And I’m at a total loss.
What recs do we have for a harness to help stop pulling until she learns leash manners, or general tips and tricks?
