I’ve fed every puppy I’ve had in my life all stages food and they’ve all lived long healthy lives. I cant comment on puppy food but in my experience I see no need. I feed all life stages with around 21-22% protein along with probiotics and fish oil and all my dogs have been very healthy with no real medical issues. That’s feeding everything from a standard dachshund to a pitbull and a Belgian malinois. I also switch proteins with every bag I buy and have zero issues. Switching proteins is something people dont do enough. Not only does it reduce the boredom with what they eat but it gives them more nutrients and aminos from the different types of protein. Just stay within the same formula and the proteins dont cause any gastrointestinal upsets. I think what’s more important than the type of food is just feeding quality food. Get the best food you can afford and your dogs will be good
