Orijen and Nutrisca for dry food are my favorites, check Chewy.com. For a reasonably priced wet food/topper, check out Newman Organics.
Your dog is a senior and therefore prone to developing bladder stones (breed) so I would soak her kibble in water prior to serving and maybe add a splash of water especially if she is not a water drinker. Make sure she gets out for frequent bathroom breaks/opportunities to urinate.
Also, check her teeth and get a cleaning and extractions if needed. Brush her teeth daily (see YouTube for how to videos)

PS: I just reread your post, if you want to feed only dry, presoak the kibble in water overnight, it will be soft, easy to chew and digest. If the food you are using agrees with her, then stick with it. You can always add a bit of scrambled egg or cooked chopped up lean meat/chicken (no bones)
Has she had a senior workup? Ask the vet that examines her what he recommends.
