Y'all are lucky your vet(s) suggest SD or Iams! Mine said Purina Puppy Chow
And they SELL both SD and Iams
TOTW is great food; they love it. Mine ate it as pups, and they still eat it. Every once in a while I switch things out (to another grain-free, of course!) so they don't get bored, and they are thrilled to tears to get TOTW back.
