Quote:Struvites: These are also called ‘triple phosphate’(magnesium ammonium phosphate) and are the most commonly seen with urinary tract infections and most frequently seen in females. These type of crystals are seen in young dogs (under a year) or in middle aged or older dogs.
Breeds that have a tendency towards getting these types of crystals are Cocker Spaniels, Labrador Retrievers, Scottish Terriers, Miniature Poodles, Bichon Frise, Miniature Schnauzers, Pekingese, Basset Hounds, Springer Spaniels and German Shepherds. Struvites are almost always accompanied by bacteria that create a high alkaline pH. Always have the dog’s urine cultured for bacteria, even if none are apparent in a microscope upon microscopic inspection.
Not all bacteria will show on inspection, but a culture will reveal if any bacteria is present. Knowing which bacteria are present allows the veterinarian to prescribe the proper antibiotic to eliminate infection. It is also noted that many dogs can have struvites present in the urine and high urinary pH with no ill effects, so if a routine urinalysis shows a pH of 8.0 and a few struvite crystals, but your dog has no symptoms of any kind, there is no need to be concerned.
When the infection is treated by the correct antibiotic, cranberry juice Capsules (not cranberry juice) can be given to the dog. These help to stop bacteria from adhering to the bladder wall and help prevent future infections. Some people have had success keeping the urine acidic, which helps prevent these crystals from forming, by feeding acidic foods and avoiding alkaline foods. A raw, natural diet is high in acidic foods.
Because bladder infections lead to high alkaline urinary pH and struvite crystals, many people, including many vets, make the mistake of treating the problem by acidifying the diet. But that is confusing cause and effect. Alkaline pH and struvite crystals are not caused by a diet of alkaline foods; they are usually caused by bladder infections. Therefore, trying to make the urine more acidic will not get rid of the infection.
Alkaline pH can also be normal, as pH can vary a great deal even in the same dog at different times of the day, and also by the way the urine was captured and handled before testing.
If your dog has struvite bladder stones, then acidifying the diet, along with treating the infection, can help dissolve the stones. Ascorbic acid (a form of vitamin C), and distilled water can help with this. , Acidic foods include chicken, beef, eggs, fish, pork, cottage cheese, yogurt, rice (brown and white), beans, nuts and all seafood.
