It also treats bacterial bladder infections, all within a controlled calorie profile that aids overweight dogs in maintaining a healthy weight.Key benefits include:
  • Dissolving Struvite Stones: The recipe is engineered to break down struvite crystals effectively.
  • Moderate Energy: Tailored calories help dogs stay within a healthy weight range, especially those already overweight or at risk of gaining excess weight.
