Bichon Frise: calcium oxalate bladder stones and the role of diet
Published by Planète Pets · managing editor: Clément Lacaille · how our guides are written
A Bichon Frise that strains to urinate or shows blood in its urine may be dealing with a condition its breed is statistically more prone to than the average dog: calcium oxalate bladder stones. Find all our feeding guidance in the dog food section.

What the landmark study shows
A study by Lulich, Osborne, Thumchai, Lekcharoensuk, Ulrich, Koehler, Bird, Swanson and Nakagawa, published in 1999 in Veterinary Clinics of North America: Small Animal Practice, analysed the epidemiology of calcium oxalate uroliths in dogs using data from the University of Minnesota's urolith referral centre (see the study). The Bichon Frise ranks among the most represented breeds, alongside the Miniature Schnauzer, Lhasa Apso, Yorkshire Terrier and Miniature Poodle, with hypercalciuria identified as a key risk factor in these breeds.
What this means at mealtime
- Generous hydration, favouring wet food and an always-clean water bowl, to dilute urine and limit oxalate concentration.
- A ration low in oxalates and sodium, avoiding excess high-oxalate foods (spinach, overly mineralised kibble) in a dog that has already formed stones.
- Regular veterinary follow-up, with periodic urine testing, since recurrence is common once a first stone episode is diagnosed in this breed.
Adjusting care to the dog's profile
A water fountain can encourage a Bichon Frise that doesn't drink much to hydrate more throughout the day; our guide to dog water fountains covers the key criteria for choosing one. Find the full breed profile on the Bichon Frise page and browse all our guides on the dog hub.
Frequently asked questions
Do all Bichon Frises develop bladder stones?
No, the breed carries a statistically higher risk than average, without this affecting every individual dog.
Is adjusted feeding enough to prevent all recurrence?
It lowers the risk but doesn't eliminate it entirely; regular veterinary follow-up remains necessary in a dog that has already formed stones.
How can I spot a urinary problem in my dog?
Frequent or painful urination, or blood in the urine, should prompt a swift vet visit, especially in a predisposed breed.
