It is not abnormal to find slight amounts of bilirubin in the urine of healthy dogs. When it is there in larger amounts, it can be due to all the causes I listed for increases in direct (conjugated or soluble ) bilirubin in your pet’s blood stream. (read here) Of the two types of bilirubin, Direct aka conjugated bilirubin is the only kind that makes it into your pet’s urine.
