Juindice or icterus is the term that is used to describe yellow discoloration of mucous membranes of the gums, nostrils, genitals, and other areas due to a high concentration of bilirubin, a normal bile pigment formed as a result of a breakdown of hemoglobin present in red blood cells (RBCs).
In some diseases, high rate of RBC breakdown results in high levels of bilirubin. As these high levels of bilirubin can not be excreted normally, they pile-up in the tissues, causing pale skin. Bilirubin can also get accumulated if its normal excretion is hampered due to some disease (e.g., cholestasis).
Accumulation of high levels of bilirubin is harmful for the dog. Bilirubin concentration is toxic and causes discoloration of the skin (i.e., jaundice) kidney and liver injury as well as brain damage.
All breeds of dogs can be affected by this condition.
