Biliary calculi are sometimes met with in dogs.

Symptoms

The symptoms make their appearance suddenly. There are the usual phenomena of colic, added to vomitings and jaundice. Towards the end of three or four days the faecal matters are found to be white. The bowels are sluggish, or even constipated. This state, which usually continues for some days, ceases when the biliary concretion arrives in the intestine, or when the biliary ducts become so dilated as to permit the free course of the bile along its natural channel. Then the foregoing symptoms give way, and the jaundice disappears a little later.

Treatment

The medicine most likely to relieve the pain caused by the passage of these calculi is Aconitum.* But if no relief should follow after a few doses have been administered, Belladonna should be substituted. A warm bath is generally beneficial.
