I would never feed just dry kibble, for one thing the dog could develop bladder stones if he is not a water drinker.
At least pour a spoonful of warm water or plain homemade chicken broth (boiled chicken water nothing added) on it.
Dry kibble alone is not good, no matter how much you pay for it.

PS: I agree with your husband, if the dog is doing well on the food, then why change it?
When you take the dog in for the next scheduled visit see what the vet recommends.
