I wrote awhile back about making homemade pet food and included a cost comparison. Since then, Homemade Healthy Dog Food and Treats – Homemade Treatments Facebook group posted an excel spreadsheet originally created by Kevin to more precisely track nutrients for homemade pet food. See his spreadsheet here.
I find this fascinating! (And, yes, it does seem that as a culture we may be more invested in pet nutrition, even as we drive our children through Mickey D’s for McNuggets.)
Here’s the spreadsheet adapted for our elderly Chow. Let me know in the comments if this is helpful to you.
