Hi sharfie –
It’s fine to supplement a dog’s diet with whole foods but I would avoid supplements that contain synthetic vitamins and minerals when feeding a balanced commercial food unless advised to do so by a veterinarian – this is especially critical for puppies because they are more sensitive to vitamin and mineral deficiencies and excesses than adult dogs. I found the website for ProBalance but I can’t locate an ingredients list. Is it a whole food based supplement or does it contain synthetic vitamins and minerals?
