Urinary S/O Canine effectively dissolves struvite uroliths. In addition, an acidic urinary pH is unfavourable to the development of bacteria, which are frequently associated with struvite uroliths.
Diluting urine decreases the urinary concentration of struvite and calcium oxalate crystals. Greater urinary volumes also ensures regular bladder wash-out.
Undersaturated urine is an environment where crystals cannot proliferate. Thus the urine is unfavourable to the development of struvite and calcium oxalate crystals.
Magnesium is a component of struvite (magnesium ammonium phosphate uroliths).



  • Struvite dissolution - Helps dissolve all types of struvite stones.
  • Urine dilution - Urine dilution makes the urine less liable to form struvite and calcium oxalate stones.
  • Low RRS - Helps lower the concentration of ions contributing to crystal formation.


RECOMMENDED FOR CASES OF; Struvite uroliths: dissolution and management of recurrence, Calcium oxalate uroliths: management of recurrence, Bacterial cystitis: management of secondary struvite crystalluria (in association with adequate antibiotherapy).

NOT RECOMMENDED IN CASE OF; Chronic Kidney Disease (CKD), Heart disease (when sodium restriction is sought), Concurrent use of urine-acidifying medication, Growth, gestation/lactation.

Brilliant company very quick on delivery cant praise them enough

Good food, fast delivery ! kassie w on 6 July 2021

Good for balancing pancreatitis and bladder stones. Low fat at 6.5 percent, which is more than chappy at 3.5 percent but there's little choice with bladder stones and pancreatitis. The dry biscuits are allot higher in fat and for a dog that doesn't drink much the wet food is the answer, although it's generally allot more expensive but cheaper than vets fees!

Appears to work well Paul C on 8 February 2019

Good value food for my Pug that suffers from Bladder Stones. Her Symptoms are blood in Urine, she enjoys it, but then again she will eat anything. Should be fed exclusively for at least a couple of months - i.e. no treats. Appears to clear up after a while, this second time we have used this in a few years. But the vet will know best.

Great price anneballinger1 on 2 March 2017
