This occurs when a solid mass made up of mineral and acid salts form in the bladder, often because your dog's urine contains too much of certain substances that form the crystals. While bladder stones can affect any dog, some dog breeds are more susceptible to certain types of bladder stones than others. For example, bladder stones containing calcium and oxalic acid (known as calcium oxalate uroliths) are more likely to be found in Schnauzers, Bichons, , and . Bladder stones containing uric acid (known as urate uroliths), on the other hand, typically affect , , and English .
Urinary So Canine at PetFoodDirect
All dogs affected with hyperuricosuria are potential urate stone-formers. At any time, a combination of high-purine foods, insufficient fluids, insufficient opportunities to urinate, and overly acidic urine might cause the formation of urate uroliths. Periodic routine urinalysis to check for urate crystals can be used to monitor dogs with hyperuricosuria. The most accurate sample for this purpose is collected in the morning, assuming the dog has not urinated all night, so the urine is more concentrated. The sample should be collected in a clean glass, plastic, or other chemically inert container. To avoid false crystallization, the sample should not be refrigerated and should be tested within 30 minutes or as soon as possible.
Topic: Struvite Crystals - Dog Food Advisor
There are some commercial urinary diets on the market that claim to eliminate both struvites and COUs. I am highly skeptical of these claims as the authors of the studies supporting them are employees of the urinary food manufacturers. I am not a fan of the diets and believe they are not nutritionally well-balanced and therefore not good for the longer term. Second, they have a higher proportion of sodium (salt) to induce thirst so the dog drinks copiously to flush the bladder. Sodium is a contributor to the formation of COUs! Excess sodium is also very hard on an older dog's bladder. Much better, IMO, just to add water to their food and scrap the high-sodium commercial stuff.
