After she sees the vet to rule out or cure a UTI, a little cranberry goes a long way. I give my females this daily. It helps to move all the urine and since I started adding this years ago, I havent had UTI in a dog in years.. ( and years..)What she doesnt need she will pass. You could even just give her a half a capsule daily. Broken in two meals. You can get them anywhere- even walmart.
