My dog had terrible bladder stones that caused a blockage which required surgery. He has been on Rx U/D food ever since (for over a year now). He seems to do fine on it, but I am wondering what kinds of things (treats, regular foods) I could give him that would not aggravate his bladder problem. According to the vet, the stones found in him were Calcium Oxalate. I have looked online for various foods that would be okay, but don't find a lot. Please let me know if anyone else has this problem, and has any advice! Thanks!
