All of the products you have recommended are implicated in cases of DCM. Only 5 brands follow WSAVA guidelines : Hills, Purina pro plan, Purina one, Eukanuba, Iams, Royal canin. I would recommend one of them to be on safe sideWhat would your husband consider extremely pricey?
Try Victor if it is available. My local feed store sells the Hi-Pro Plus for $45 for 40lbs, some of the formulas cost less.
Fromm Classic or Fromm Gold (Gold is more expensive)
Diamond Naturals is an ok food that is generally not too pricey.
Taste of the Wild if you need grain free.
If I had to feed a Purina product, I'd probably go with Pro-Plan, or One Beyond.
