Generally, meats are acidifying and increasing the protein in the diet can help with struvites. Try using meat treats like Stella & Chewy’s Carnivore Crunch or Kisses, Vital Essentials freeze dried nibbletts, Fresh is Best dehyrated meat treats, Pure Bites, or some safe jerky. But you also want to increase fluid intake with these dried treats and overall to flush out the bladder. A wet food diet might be better. When her UTI is gone and she’s on regular food, give her urinary tract supplements. There is one called Wysong Biotic pH- and Clear Tract or Berry Balance, etc.
