Illnesses such as stones and cystitis take over when there is a growth of bacterial colonization in the dog's urea and urinary tract, or when saline sediments become detached from the dog's urinary ducts causing (in addition to pain in urination) possible bleeding.

Whether due to age or the intake of food that has irritated the urinary tract, struvite and stones can affect dogs as young as old. Supplements protect the proper health of the urinary tract and help fight the buildup of harmful substances.
