Prince Poodle had 2 UTI’s a couple years ago. Since I switched him to all wet/moist food (4 or 5 star rated only) and some homemade food (recipes from Feed Your Best Friend Better by Rick Woodford) and bought him a circulating pet fountain, the UTI’s have not returned. Definitely try that out. I just had him blood tested again (they tested him for diabetes after the 2nd UTI) and his blood tests has improved quite a bit.
There is one type of rare bladder stone that does not appear on x-rays. When I took Prince in for his 1st UTI, my vet told me he had only removed 2 such stones in his whole career. And he has them in a baggy and showed them to me. 😛 I’m assuming your vet is aware of that and is investigating it.
Solid Gold brand also makes a product called Berry Balance, for urinary health. Don’t use it at the same time as prescription dog food (I’d avoid most RX dog food if you can help it).
