I was revisiting the possibility of going back to C. Natural due to some recent skin allergies that have come up. I need a limited ingredient food and, after careful research, I'd settled on the C. Natural Lamb and Rice ALS formula but upon closer observation I see that it has Calcium levels of 2.14 and Phospherous level of around 1.33 (although the grain free formula has a Phospherous of 1.16.) It was my understanding that the ideal Calcium/Phosperous ratio for a large breed dog should be around 1.5 Calcium/1.0 phosphorus. I believe Bulldogs don't stop growing until around 2 years old so I'm a bit concerned that a Calcium level this high might not be the way to go. I know there are other Limited Ingredient foods out there but there's some concern about the meat content and they tend to be lower in calories and fat...
