Hill's PRESCRIPTION DIET
u/d Dog Food
For the Nutritional Management of Dogs with Urate or Cystine Urolithiasis (stones in the urinary tract, most often urinary bladder) associated with a variety of signs including frequent urination, blood in the urine, straining to urinate, and a painful abdomen. Certain stone types may initially be managed by physical removal (often via surgery) and then followed with proper nutrition to help decrease the risk of stone recurrence.
Prescription Diet u/d Dry Dog Food was developed to aid in the management of dogs with the problems associated with urate and cystine urolithiasis. Controlled amounts of protein, decreased purine intake and uric acid excretion, and the target urine pH (alkaline) lowers the risk of forming urate crystals and uroliths.

For the Nutritional Management of Dogs with Urate or Cystine Urolithiasis (stones in the urinary tract, most often urinary bladder) associated with a variety of signs including frequent urination, blood in the urine, straining to urinate, and a painful abdomen.

Controlled amounts of protein, decreased purine intake and uric acid excretion, and the target urine pH (alkaline) lowers the risk of forming urate crystals and uroliths.
These characteristics make Prescription Diet u/d veterinary dry dog food, a useful nutritional aid for dogs with urolithiasis.

Indications:
Primary Indication:
- Urate & cystine urolith management
Other Indications:
- Copper storage disease
- Hepatic encephalopathy
- Portosystemic shunt
- Uraemic encephalopathy
Not Recommended For:
Growing puppies, pregnant or nursing dogs.
Patients with struvite urolithiasis, hyperlipidemia, hypoalbuminemia, pancreatitis, history of pancreatitis or at risk of pancreatitis.
Evidence-Based Clinical Nutrition:
The nutrition of Prescription Diet u/d has been shown in multiple studies to decrease the building blocks of stones in dogs prone to the development of urate stones.(1-6)
Additional Info:
Decreases purine intake and uric acid excretion, which lowers risk of forming urate crystals and uroliths.
Protein level is sufficient for maintenance of adult dogs, yet low enough to dilute urine by decreasing urea production.
Urine pH of individual dogs may vary due to complicating factors such as time of feeding before urine collection, type of urine collection, individual animal variation, or test methodology.
Note: Dogs on low protein foods such as Prescription Diet u/d Dry Dog Food commonly exhibit unusual laboratory values. Specifically urine specific gravity (USG) is usually less than 1.020 and blood (serum) urea nitrogen (BUN) is less than (10 mg/dl). Monitoring USG, urinary pH and BUN are methods to monitor the food's effectiveness and owner compliance
Long-term use: Dogs fed Prescription Diet u/d dry food long term should be monitored for the development of protein depletion. Because dogs with urate or cystine urolithiasis may have underlying metabolic abnormalities, we recommend performing a fasting serum chemistry profile and echocardiogram every 6 months in these patients.
