That's why a product like Cranberry Relief is much better because it is concentrated. Not just water, you have to drink huge amounts of cranberry juice to see the benefits.
As you said, though, it's a preventative, not a cure. Given on a regular basis, it will neutralize acidic urine so bacteria, crystals and stones can't form. An infection needs antibiotics. Your vet also needs to check her urine for crystals.
