It's my understanding that beef is the last protein to intro and organs come after all proteins. It's how I did it when I followed PMR. Ecko only had cannon butt one day and that was the first day. Occasionally I'll give too much of something and not enough bone to counter it but it's very rare anymore. I don't feed fruits or veg either. The occasional green tripe is about it. But I do use coconut oil and fish oil. Ecko doesn't like veg anymore. He used to eat whatever I put in front of him, now if it isn't raw meat or organs he snubs his nose. Won't even eat cat kibble, or the kitty litter buffet. LOL
