I like to free feed as well. It's been tough with them eating each other's food all the time
I don't want to have to crate them to eat. I wouldn't want to eat in a crate. Lol. I was thinking that 38% seemed a bit high for protein. They're all doing so well on their food right now. I hate to change, but it would be tremendously more convenient if everyone ate the same food. Fromm's 4-Star line would be my first choice, but I have a finicky one who won't eat it. It's interesting that there's not much of a difference between most "adult" foods vs. ALS foods. I found an interesting article on Canidae's website about ALS food & nutritional requirements at different life stages:
