This reply is a little late, but it seems like you’ve done a bunch of research! Good for you!
I personally like to rotate brands after every bag. I have 4 brands right now and when one is done I move on to another that has a totally different protein source.
For instance, I use Valens (Chicken & turkey), then Farmina (boar), then Petkind tripe (Venison), and then Nutram (Lamb).
I like to keep the protein content of the brands around the same, around 28-30%. I’m sure as you try different formula’s, you’ll find a good ratio of proteins, fats and carbs that works for your dog.
For toppers, I like to use K9 naturals canned tripe and olewo carrots. (The carrots are really good for helping with healthy firm poops) I also like to add some green lipped mussel powder.
I’m sure with time, you’ll find what works best for your little guy. He’s super cute by the way!
