I've been feeding my dog kibble (Blue Buffalo) according to this:
But I'm currently wondering whether adding home cooked food would be more beneficial towards her. I do feed her Nature’s Variety Instinct Raw Frozen Diets as well but was wondering if there was more variety I could add to her diet.
Keep going with the raw, but incorporate other brands for variety. Also look into adding some unique meat cuts, and definitely do some raw meaty bones at least three times per week to help maintain dental hygiene.
As you get more confident, you can look into increasing the amount of homemade raw you feed. The general guidelines for formulating a prey-model diet are pretty easy: 80% muscle meat w/ fat (aim for around 20% of this proportion in fat), 10% bone, 5% liver, 5% other secreting organs; aim for at least 50% red meat, and at least four different proteins, supplement with fish oil or raw oily fish (sardines, mackerels, herring, etc..). In theory this should all be balanced, but it never hurts to add a whole-food-based multivitamin, Nupro is very good and Standard Process makes another good one.
