I really wanted this to be great for my little girl pup with her UTI. I tried the recommended dosage, she got a little better, but I started giving her a little more, then she really seemed to feel better. Unfortunately the dropper that came as part of the lid just would not suck up more than a small amount at a time no matter what angle you tilted the bottle so I would use it twice for the amount I needed. It did make it harder to get the true correct amount to give your dog. My Ginger also did get a little heartburn (stomach upset)from it so needed to give her milk a couple times, but she is still getting better. I hope it was just a fluke to get a dropper that really didn't work well. I also alternated this with another chewable cranberry tablet too ease her tummy upset, that really helped.
