Before You Buy
Key Buying Factors
01
Prescription vs. Over-the-Counter
Prescription diets are clinically proven for conditions like struvite stones and should be used under veterinary guidance. Over-the-counter options are for maintenance or mild support.
02
Key Nutrient Profile
We look for controlled magnesium, phosphorus, and calcium levels, plus slightly acidic urine pH (6.2-6.4) to discourage crystal formation.
03
Protein and Sodium Levels
Moderate, high-quality protein and restricted sodium help reduce kidney workload and urinary mineral concentration.
04
Moisture Content
Higher moisture from wet food or adding water increases urine dilution, reducing crystal risk. Dry food is convenient but may require hydration encouragement.
05
Added Ingredients
Omega-3 fatty acids, antioxidants, and prebiotics support urinary tract health and overall immunity.
06
AAFCO Statement
Ensure the diet meets AAFCO nutrient profiles for the dog's life stage, and ideally carries a veterinary therapeutic claim for urinary health.
Living With It
Care, Cost and Maintenance
Follow Veterinary Guidance
Always consult your vet before switching to a urinary diet. Prescription diets are tailored to specific conditions like struvite or oxalate stones.
Encourage Water Intake
Provide fresh water at all times. Consider adding water to dry kibble or offering wet food to increase moisture and flush the urinary tract.
Monitor and Follow Up
Regular urinalysis and imaging help track effectiveness. Feeding the diet for the recommended period (often 4-6 weeks) is critical for dissolution.
Pro tip
When transitioning to a urinary diet, mix the new and old food gradually over 7-10 days to avoid digestive upset. Ensure the diet is fed exclusively-no treats or table scraps that could alter urine pH.
Frequently asked questions
Can I feed urinary diet without a vet prescription?
Prescription diets require veterinary authorization because they are intended for specific medical conditions. Over-the-counter urinary support diets are available but are less potent.
How long does it take for urinary food to dissolve struvite stones?
Typically 2-4 weeks, but it can take up to 6-8 weeks. Veterinary monitoring with imaging and urinalysis is essential.
Is dry or wet urinary food better?
Wet food provides higher moisture, which dilutes urine and helps prevent crystals. Dry food is more convenient. Many vets recommend combining both.
Can urinary food cause side effects?
Some dogs may experience loose stools initially due to changes in fiber or protein. Transition gradually and consult your vet if issues persist.
Are there natural alternatives to prescription urinary diets?
No natural diet has been clinically proven to match the efficacy of prescription diets for dissolving stones or managing urinary disease. Always prioritize vet-recommended nutrition.
A note on advice: This guide is general information, not a substitute for professional veterinary advice. Talk to your vet before changing your dog's diet or care routine, especially if your dog has allergies, kidney disease, pancreatitis, obesity, heart disease or any other medical condition.
