Well I am not a trained nutrionist, and I switched to raw food about 6 or more years ago. Because kibble was ruining my pups digestion. Liquid diarrehea on three or four different high quality kibble.
With a big dog, that is a whole hell of a lot to clean up. And quite frankly I was very concerned.
Year two I found a vet nutriontist but first year, I just researched on line. I feed a 40 40 20 diet. From the first week on, clear poops, no diarrehea. But week three was the watershed mark. No more diarrehea almost ever in 6+ years unless he gets into the garbage, and or, takes down the turkey on the counter
He has white teeth, good breath, shiney coat, and quite frankly I don't need to worry about kibble recall.
Due to our cross border travelling, I do let in some kibble, because I can't take raw dog food over the border, so until I get situated there is something they can eat.
But now there is freeze dried raw, in pet food stores throughout most of the USA. I can google the city I am going to, and find out where I can buy it there.
Now for show breeders who have bearded dogs, which I am sure they already know, but you can make little meatballs and hand feed them at meal times, so that meat doesn't get into the beard. But likely you will need to miniwash the beard/face, even if you wrap.
I use a bacterial spray onto the beards after dinner even if hand feed. Then I brush out the big dogs beards. Takes about 5minutes per day if done daily. Usually by day three, I need to put them into the dog wash, for a more thorough wash of their head trimmings. And condition really really well the facial furnishing.
I wash all my show dogs weekly and blow dry. Some would say this is too frequent, even my trainer says so. But hey every day, they are out and about, through rain, mud, grass, sand, lake water etc. I might go to 10days, but not much longer than that.
