ROYAL CANIN® Veterinary Health Nutrition Since 1968, Royal Canin has been following the belief that nutrition plays a key role in supporting the health and wellbeing of cats and dogs. This is why we have designed ROYAL CANIN® veterinary diets around proven nutritional science in partnership with pet professionals and experts, delivering nutrition for pets with specific health needs.
For dogs with urinary sensitivities, a specially tailored diet containing precisely balanced nutrients can help to support good urinary health. ROYAL CANIN® Urinary S/O dry dog food is specifically formulated with the nutritional needs of dogs with urinary sensitivities in mind.
This urinary food for dogs is suitable for dogs with:
- Struvite uroliths: dissolution and management of recurrence.
- Calcium oxalate uroliths: management of recurrence.
Key Benefits:
Urine Dilution
o ROYAL CANIN® Urinary S/O's exclusive complex helps to dilute your dog's urine, making it less likely for calcium oxalate stones and struvite stones to form in the first place.
Struvite Dissolution
o Struvite is a normal component of your dog's urine that can form crystals or stones if the urine is too concentrated. ROYAL CANIN® Urinary S/O helps to dissolve all types of struvite stones that may form in your dog's bladder.
Low RSS
o Relative Super Saturation (RSS) methodology is utilised for the development of ROYAL CANIN® Urinary S/O. RSS helps to lower the concentration of ion in your dog's urine, minimising the likelihood of bladder stones forming.
Low Magnesium
o As magnesium is also a natural component of struvite crystals, ROYAL CANIN® Canine Urinary S/O is formulated with a reduced level of magnesium.
As part of the ROYAL CANIN® Veterinary Health Nutrition range, it is important that this product is only given to your pet when recommended by a veterinary professional. To cater to each dog's individual preferences, ROYAL CANIN® Canine Urinary S/O is also available as wet food in either a delicious gravy or a soft and tasty loaf. If you're considering mixed feeding, simply follow our feeding guidelines to ensure your dog gets an accurate amount of both wet and dry food for optimal benefit.
Please note: ROYAL CANIN® Canine Urinary S/O dry dog food is not suitable for Chronic Kidney Disease (CKD), heart disease (when sodium restriction is sought), concurrent use of urine-acidifying medication, growth, gestation, lactation.
