I agree that I wouldn't be happy with the food the breeder has her on, but if the breeder won't change her food you don't have much choice. If I were you I would keep her on whatever food the breeder has her on for a week or two while she gets settled at your home. At her age--although it's not good food--that short a time it's not going to hurt her while she gets settled in. When you feel she's comfortable, you can start to transition her. Most of the time it gives transition instructions on the bags. It's usually 75/25 old/new for a few days--when she tolerates that, go to 50/50, then 25/75, then 100% the new food. Sometimes they transition 100% on their own by picking out the new food and leaving the old. lol I would absolutely wet the ZP, but I think the breeder isn't familiar with the consistency of ZP. She is thinking it is hard like kibble, but it's not. Of course, it's not soft as canned food, and I don't think it will soften much even with soaking, but she should be able to chew it without issue. Let us know how she does.
