This is just me, but yeah, I think you are. Breeders usually don't feed each puppy separately but together, so it's extra work that way: prepare separately, separate puppy to eat. Then, what if you back out at the last minute? That's how I got the puppy I have now. He was 8 weeks old when the person who had reserved him backed out instead of coming to get him. It happens. Raising a litter of puppies right is a tremendous amount of work, and the older they get, the more work it is. I had no idea until I became friends with a breeder and saw what she did for a litter.
One of my puppy's littermates is being converted to raw once she finishes the small bag of what the breeder was feeding that the owner purchased. People who feed kibble get to do the same if they want to feed something other than what the breeder did or can't get it where they live.
So unless you really believe the breeder is feeding inferior kibble, in which case you need to be one of the ones who backs out because she didn't feed the bitch well before and during pregnancy, just figure it's only a few weeks and plan on making the change yourself after the puppy's home and settled in.
