Provides nutrition that aids in the management of pure struvite uroliths.

Relative Supersaturation (RSS) methodology predicts the crystallization potential of urine. RSS is used to develop diets that lower the concentration of ions contributing to struvite and calcium oxalate urolithiasis.

Increasing the urine volume reduces the saturation of urine with calcium oxalate and struvite crystals.

Contains nutrients to support healthy teeth.

Specially formulated to assist in the management of struvite and calcium oxalate crystals and stones in small breed dogs (less than 10 kg).

Loving my small dog

Great product

My Vet first recommended the Purina version of this type of dry food, but my dog would not eat it. Your dog food was recommended second by my Vet and my crossed shih tzu/poodle, ate it immediately. It is wonderful that you make a small breed morsel size. My dog has been on your food for over a 1.5 years and is it keeping his urinary track healthy.

Urinary SO for small dogs

April has now been on this formula for two weeks. She is a ‘very’ picky eater. She is cleaning her bowl.

Super Happy and grateful!

[This review was collected as part of a promotion.] My shitzu started with little bleeding in his urine. His exams indicated he had crystals. The vet recommended that I replace her food with URINARY SO. After two months we repeated the exam and fortunately the crystals have disappeared, her exam came out perfect! So I am super happy and grateful.

Works great!

My female pug has been on this food for several years. Before going on this food she had issues with crystals and frequent UTIs. We have almost no issues now. And she absolutely loves the flavor and runs to her bowl at dinner time. It’s been a huge blessing!

[This review was collected as part of a promotion.] Keeps our dog extremely active & she feels& looks so good . We threaten to eat her food ( LOL) just to be as alert ,active & full of energy plus she has great coat . She acts like a puppy!! She likes to wake up 6 am JUST to eat not to go outside just loves the product that much. She is very frisky & we believe it’s the product .

Very effective control of UTI

[This review was collected as part of a promotion.] Our pug Zoey developed an UTI, the vet suggested we try Canine Urinary SO. We have not had another. This change seemed to solve the problem.
