Hi. My dog, Otis, has urate stones. He had two surgeries to remove them recently and I found out last week that some stones are back. I switched to Hills U/D and more water intake with food. I'm desperate to find anything else that will help him to avoid surgeries. Clearly, he cant have surgery every two months. I want some raw food options to add to his Hills U/D diet. I've been researching online and I see that they can have bananas, apples and pumpkin? All of these options are low in purines. Can these raw foods help with dissolving stones? Is it okay to give him these foods? I'm so scared to give him anything because I don't want to make it worse.
