Few things in this.
There are many studies showing that high protein causing kidney damage in dogs is a myth, and 30% isn’t terribly high either-it’s actually the number i shoot for at minimum, and i supplement with high protein canned and dehydrated on top of that. That shouldn’t be a concern for you, and lower in fat is more important for weight loss than lower protein.
However, I wouldn’t continue feeding blue. If you want to stay on a weight loss food (i’ve never personally used any) the two I see recommended the most on here are Wellness Core Weight Control, and Annamaet Lean. I’ve seen a few people use Natural Balance Fat Dog as well, but I won’t feed anything from that company either.
