It has long been recognized that some Bichons Frises have a predisposition to formation of urinary stones (uroliths). This condition is known as urolithiasis. There are several types of stones that can form in the bladder, with struvite (also called magnesium triple phosphate or “infection” stones) and calcium oxalate being the most common in Bichons.
