Pat C,
If your dog can have chicken, I’d go with the Ultra as there is no health negative with this level protein and ultimately the fat level is good for most healthy dogs. I think the only concern here for you is that you noted your dog needs to lose a few pounds; so you might wish to either up your exercise or factor that in to how you feed in the short term, having lower fat, to reach ideal weight. Then just check your dog’s weight periodically and adjust the amount of food and exercise.
I think if your dog is going to remain on the inactive side long term and shows weight gain on the food, then you would consider a different formula with lower fat or simply feed a little less/adjust treats to low calorie/fat healthy fresh food “bites.”
Ideally, I personally would prefer a bit higher protein minimum and for healthy ideal weight dogs a bit higher fat than the Option (24/13). At 26/16, Extra’s levels appear very slightly better.
But I’ve never had an issue with higher fat in a food causing weight gain in my own dogs — and mine usually have needed the higher fat (weight maintenance, good coat & skin)!
One thing to consider that you haven’t mentioned:
Be careful re planned daily long term feeding of rice, particularly brown rice, depending upon sourcing in the US. It’s shown very, very high levels of arsenic when sourced from Arkansas, Lousiana, Texas (former cotton growing South) from the land (residue); humans have been advised to avoid consuming very frequently and/or choose less contaminated sources (California, India, Thailand, outside US). It would be another reason to choose more than one formula/carb base & company.
