Hiiii, I am so excited that you are getting your puppy especially that you are doing so much reading about nutrition and other things! before she comes home.
I would not feed my furbabies the 2 brands you mentioned. I look at protein content, fat content, ingredients that are human grade. I love innovas website for listing the ingredients and their nutritional value. I have had Jazzie on Innova for almost 2 yrs. Zander was tired of it, sometimes it can be too rich for some dogs palate
so I switched him to Calif. Naturals. We have been on Wellness, natures variety, as well. With the wellness Zanders hair looked oily within 3 days of a bath, with natures variety they both had reverse sneezing, it stopped once I switched them to Innova. I love Calif. naturals because their recipe is simple, the least possibilities for allergies, etc.
Good luck with your choice.
