I see this is an older post but maybe someone will read it and it will help. My Maltese Bichon started getting Oxalate stones when he was 7 years old. He ended up having 3 operations roughly every year and 3 months to remove the stones. Through that time he had specialized dog foods like Royal Canin S/O , etc.. but nothing worked. A little over 3 years ago I came across an article on Oxalate stones in humans and how these people swore by Magnesium as getting rid of their stones. I studied the amounts for dogs weights and such, it’s a very small, miniscule amount, and it’s been 3 years of him being stone free. He’s 14 years old now and acts like 5. Before adding the magnesium I had started him on a people food diet. He still eats small Milk Bones for treats and loves Beggin Strips so he’s not being deprived of some dog treats, even though the milk Bones have calcium in them the Magnesium seems to negate that. I wish I knew how to write blogs so I could shout the benefits of Magnesium to the world on this but am not computer savvy. On a side note, I also have a female Shih-Tzu who had her stomach x-rayed for a different issue and stones were found. I immediately started giving her Magnesium and she may have just urinated them out but she has never had stones since and that was over 2 years ago. Please anyone reading this , try Magnesium, it has been a life saver
