Hills Prescription Diet s/d key benefits

Magnesium, Phosphorus
Reduced Decreases urinary concentration of struvite constituents, magnesium, ammonium and phosphate.
Energy Increased Reduces food intake and thereby mineral intake.
Sodium Increased Increases urine volume to decrease urinary concentration of struvite-forming constituents
Target urinary pH Acid: pH 5.9 - 6.3 Increases the solubility of struvite
Vitamin E
High Neutralises free radicals to help combat urolithiasis. Vitamin C is not supplemented because it is a precursor of oxalate and may increase the risk of calcium oxalate formation with diets for struvite dissolution.

Additional information

  • The transition to feeding s/d™ Canine should ideally take a period of 7 days.
  • Monitor the urine and control urinary tract infection throughout dissolution. Urinary pH will increase if infection with urease-producing bacteria is not eliminated. Urinary pH must be continuously acidic for successful dissolution.
  • Dogs fed foods with a restricted protein content commonly exhibit unusual laboratory values, e.g. it is not ncommon to find a urinary specific gravity below 1.020 and a plasma/serum urea value less than 1.7 mmol/l (10mg/dl).

Ask Your Own Question

Since commencing S/D food my dog has black solid stools is this normal?

3rd Nov 2015

After commencing Hills S/D food my dog is passing solid black stools.Is this normal?

  • Non-Executive Director

Diet can certainly affect the stools and firm, almost black stools are perfectly normal. They are probably the ideal type of stool to be produced in fact. (If the stools are soft and a greenish-black colour then that is not good, but a very dark chocolate/black is ideal.

My dog is constantly weeing as she is on hills a/d but she is olso going when asleep

  • Non-Executive Director

The weeing will not be due to the food. It sounds like she is incontinent. Why is she on this food anyway? There is more to this and you need to talk to your vet about it.

My dog has been tolf to go on hills s/d

My poodle has stilvite crystals she has had the c/d but now has to have the s/d how much difference will this make and how long can she stay in this one

  • Non-Executive Director

S/D is regarded as more effective at dissolving crystals and can be used for 2-3 months. It is not ideal to continue for longer than this as it is not a long-term diet. C/D is fine to give long-term and is intended to prevent new crystals from forming. It can dissolve any which might be present already but not as effectively sometimes as S/D.
