Here's some information and you should probably go looking for more.
Diamond is a big manufacturer of dog food. I couldn't tell you how the food manufactured under their own name has had the fomulas developed.
I haven't gone and looked at formulas for any of the manufactured under the Diamond name. You should do that.
Diamond also is a major manufacturer of kibble under formulas that are provided for them by the company whose name they will be manufacturing under. At one time and they may still be the actual manufacturer of several of the Costco kibbles. Most of my experience is from these kibbles. For years I have fed primarily Purina ProPlan--and mostly adult formulas--these are now labeled as ProPlan Focus Chicken and Rice or ProPlan Focus Sensitive Skin & Stomach (salmon and rice)--those two have been my go to kibbles for a good many years now. Purina manufactures other proteins under the ProPlan Focus label but those are the two I most often feed.
Several years ago I was showing a male who was hard to keep weight on and hard to get to eat when showing away from home. He was on ProPlan Chicken and Rice--he liked it but was dropping weight at every show sometimes because he didn't eat quite enough and sometimes just because he was very hyper at shows he tended to lose weight. I went looking for something he'd like as well as the ProPlan Chicken. At Costco I looked at the ingredients in the Kirkland Chicken and Veg--it was close to the ProPlan but a little higher in calories. The combination of ProPlan and Kirkland worked-- and I kept him on the mixture for several years.
After playing around with adult vs various puppy formulas including large breed puppy food I went back to feeding Adult food to every one--even the puppies--most of the adult formulas are labeled as be ALS (All Life Stages)--this has worked fine for close to 20 years.
You need to do some more investigation. The few kibbles I've looked at that include probiotics actually have these in such small quantity as to be non effective on their own. Also, it's questionable whether you need to include probiotics in the average dog food--for a dog who isn't utilizing food properly adding probiotics makes some sense but I keep reading the information that shows up in various vet journals on studies abut things like this and it seems to me to be questionable whether the addition of probiotics to every dogs food is really necessary. The recent literature doesn't see to think so.
Good luck on your search. The recent information on feeding (mostly via the cardiologists) is to stick with foods manufactured by big companies (Purina, Hills, Royal Canin and Eukanuba/Iams) who formulate foods with the help of nutritionists specializing in canine and feline nutrition, who do long term studies using live dogs to see if the food is well received and actually does what they think it'll do. Avoid boutique brands (often formulated by computer models which often doesn't replicate what a live dog or cat needs.) Avoid food using odd or unique carb products (legumes, potato, strictly vegetarian formulas as they may not be providing all the micro stuff a dog or cat may need,
Again, good luck--while reading and comparing try to find products that list included items and explanations of what it provides.
By the way--almost all foods have had recalls at one point or other--some are voluntary and some are not. Recently Purina recalled some canned foods that had been found to have Vitamin D in quantities that were too high--I don't much worry about this kind of recall--you aren't likely to kill a dog or cat on one can of food or even a whole case but when the FDA makes a food company recall whole batches of kibble from one plant because of finding spoilage in an ingredient of contamination by fungus of a part of the cereal used--those I worry about. Vet clinics are often the first places to know about a recall and what it was recalled for. Discuss this with your vet.
And having grown up with dogs and on a plot of land big enough to have some horses and have been involved in raising one cow/steer a summer who would be slaughtered in the fall for meat I can tell you that I doubt that anyone will ever convince me that dogs need human quality meats/carbs etc in their food. You haven't lived until you've yanked the 6 year old Boxer and the 9 month old Doberman out of a hole they've dug where the guts of this falls beef were buried a week ago--then you tie the dogs to a fence post, hook up a hose and find some shampoo--hose off as much rotting slime as you can before you apply the shampoo--lather once and rinse twice and confine to the basement until dry and you go back to fill in the hole and put big rocks on top of it.
And were the lovely dogs any the worse for wear? Oh no--they spent most of the evening sleeping off their rotting dinner and were greatly disappointed to find it out of their reach in the morning.
