I'm sorry your baby is sick. I suspect the Blue might be causing her issues. I home cook for my little girl, but she doesn't eat before I go to work. Just in case she's hungry, I leave her some kibble. I presently am using Nature's Logic, but it may be too high a protein level for Piper. I also really like Fromm, a company that has been around for over 100 years and never has had a recall. They have puppy food, but they also have food that is all life stages, which would be good for all of your dogs. I order from chewy.com. They are an excellent company, and I don't think it's ever taken more than two days. Shipping is free for a $49 purchase; otherwise it's only $4.99. They take returns without a problem, usually just asking you to donate the item to an animal shelter. I buy Katie's toys there, too, and their prices are excellent.
