I have read many post out there about reoccuring UTI's. Our little male Pom was having a bout of the same and for the past 2 years we have kept them at bay by adding 1/4 t. Of Buchu Leaf powder to his food 2x a day. He hasn't had one since. And a friend came to visit and asked if I had any "cranberry juice" I immediately "knew" what she needed and gave her some Buchu powder too - 2t. and she was fine the UTI never set in! Goggle it as it has been used for years for UTI's in both animals and people. I do not know the long term effects if any, but know it works for now.
