I am voicing my opinion, just as you are voicing yours.
Hundreds of people read this forum, so maybe someone else will benefit from what we have to share.
Also, maybe if the OP spoke to the breeder about her concerns, the puppy could spend a couple of more weeks with the mother and littermates? Could be an option, especially if a veterinarian that examines the pet agrees it would be helpful. I am assuming it would be a healthy environment for the puppy to return to, of course.
Otherwise, I am sure that the OP will do the best she can to nurture the puppy.
If you are looking for high quality small bite sized kibble, check out Wysong and Nutrisca.
Plus, you can soak any kibble in water overnight in the fridg.
Best of luck.
