Royal Canin Veterinary Diet Urinary S/O Dry Dog Food 13 kg
ROYAL CANIN Urinary S/O supports the urinary health of your dog ROYAL CANIN Urinary S/O is a balanced and nutrient-rich formula that has been specially developed to help dogs with urinary problems such as struvite crystals and stones. Dissolving struvite stones The nutrient mixture contained in this formula helps to dissolve struvite crystals and stones that can form in the bladder. Low RSS value This formula has a low RSS value (relative supersaturation). This reduces the ion concentration and prevents the formation of possible urinary stones. Dilution of urine This food dilutes your dog’s urine, which makes the formation of struvite and calcium oxalate stones difficult. Low magnesium content This formula contains less magnesium – a natural component of struvite stones. S/O index This food also creates a urinary environment that makes the formation of struvite and calcium oxalate stones difficult. Important comment This product is a veterinary food from ROYAL CANIN ’s Veterinary Health Nutrition range. Therefore, it is important that the food is only fed on the recommendation of a veterinarian. This ensures that your pet gets the food it really needs. A dietary change should be made carefully and gradually over a period of 7-10 days. Make sure that the portion size is correct – especially with mixed feeding. Mixed feeding possible In order to meet the individual preferences of all dogs, ROYAL CANIN Urinary S/O is also available as wet food with small chunks in gravy or as a soft mousse. * Mixed feeding gives the food different textures, which can stimulate appetite. Wet food has a more intense flavour and its moisture content helps to regulate the pet’s water balance. Dry food, on the other hand, is easier to absorb and good for the teeth.

I purchased this bag of kibbles for my dog who has bladder crystals and she didn’t particularly like the taste of them, so left them sitting in her bowl. Along comes her canine sister and decides that she would try them. Within half an hour, she started acting strange. Running through the house, panting, shaking, getting itchy sores all over her body literally before our eyes. Her gums turned a cherry red colour and her heart was racing. Long story short, the Vet said she had an anaphylactic reaction to these particular kibbles. Obviously they are excellent quality and they suit some dogs, just be careful when introducing them to your pet for the first time.

My little rescue Foxy Cross came to me with a very large bladder stone, and within days had to have major abdominal surgery and removal of said stone. Now the Vet has advised keeping her on these Canin Urinary S/O dietry food to reduce the chances of another stone formation. So far she enjoys both the dry food and the wet and we've had no tummy upsets with the rapid change of diet!

Great food, prior my girl had non stop blood in urine. It was difficult to find a suitable good as she also has severe allergies. Since being on this her itching has also stopped.Good quick delivery, only complaint really is from my delivery courier who would like to see the food box less with wrap around. Totally understandable as I purchase 6 or 8, 15 kg bags each month. Each box weighs 30kg which is far too heavy. I have to take bags of food out of the box on my doorstep as I can’t lift boxes. I’m also struggling to dispose of so many boxes each month

Never fails no UTI’s for 3 years now. My chow loves this food she can’t get enough! It has a nicer smell to other brands we have bought and the kibble sizes vary however that doesn’t phase my chow. She absolutely loves it.
The product was very good value for money and came in its original packaging. It was not damaged in any way. I have used this product for a few years now and shall definately order from you again. The order came promptly and within the specified time limit and the outside packaging was not damaged either.
My golden retriever has been on this food for 2 years and she loves it. We haven't had any urinary problems since. Previously we were at the vets every few months with urinary infections and crystals. I highly recommend this product, and the fact it assists with my dog losing a few pounds and maintaining her weight level is a bonus.
Excellent product. Have used this product for the last 5 years since advised by my vet to keep my dog from constant urine infections. I give her half her daily allowance -minus some to allow for the wet I add- in the morning and the other half late afternoon. She also has each time an 1/8 of a tin of 410g Royal Canin Urinary S/O Loaf so I can sprinkle her prescribed Nutracys+ powder on top. I wouldn't give her anything else. She eats it all up with no fussing. This combination has worked perfectly.
My beautiful Golden Retriever Skye , was diagnosed with Struvite Crystals in her bladder, which was very painful for her. Our vet recommended we put her onto the Royal Canin Urinary S O dry dog food. Since being on this special food she has not had a single flare up of Struvite Crystals or any other urinary problems. It is expensive, but worth every penny because it prevents Skye having a lot of pain, and with vet fees being so expensive, it is cost effective. Skye enjoys her special food and we both highly recommend it.
my wonderful vet recommended this with my adopted Tibbie who was in terrible pain with bloody urine. Tests revealed stones. Vet recommended I try it for several weeks trying to avoid expensive surgery - It worked; after further tests showed dissipation of stones and is still working 18 months later. dog is happy and so am I.STRICKLY this diet to maintain condition!
