[nagdu] Question about decreasing acidity in dog's urine

[Hope Paulos]

Hi all. I'm wondering if anyone might be able to give me a suggestion for decreasing the acidity (or ph level) in my dog's urine. I took her to the vet about a month ago. They did a urinalysis  to rule a UTI. No bacteria was found; however, they found that her PH level was 9, and it's supposed to be 7 (neutral). The vet said that they could give me prescribed food, but I'd like to go the natural route first. Can anyone give me suggestions on how to make her urine less acidic
Any help you can provide would be greatly appreciated.
