Snickers eats high protein everything, down to his snacks and potty treats! He is doing amazingly, but I think he is built for it.
He eats:
Nv Raw Medallions (1-2 per day)
Evo kibble-by Innova, I LOVE this kibble. Free-fed, always out, 42% protein
Evo biscuits as snacks (grainfree/high protein)
Freeze dried Chicken for potty treats (whopping 80% crude protein)
Fresh fruit as snacks as well
He loves it all...I'm not having any eating problems with him and he devours all of it.
If you feel your pups like meat (ie the chicken and turkey you give them) maybe you can consider a raw diet for them? I think their love for meat is why you're considering a high protein kibble? I think it might be good for your pups as well. Here are some other higher protein kibble choices if you go that route:
Innova Evo
Nature's Variety Instinct
Wellness CORE
Taste of the Wild
Blue Buffalo Wilderness
Good luck
