Hi, thanks for using Petco Pet Education Center, formerly Petcoach!

I recommend preventing urinary tract infections and using a prescription urinary diet to prevent struvite bladder stones. I like Royal canin SO, Hill's science diet c/d or Purina UR. For example is Royal Canin SO the maximum magnesium in the dry food is 0.08%. That will be hard to match over the counter.

I hope this helps!
