Though it may be harder to see on some breeds, all dogs and cats can get jaundiced yellowish skin.  Check the gums, whites of the eyes, base of the ears, nostrils, abdomen, and genitals, as the jaundice may be more noticeable in these areas.  If you suspect your pet has jaundice, take him to a vet for immediate examination. If you pet has jaundice, he has an underlying illness, such as hepatitis or other liver problems, that will require veterinary treatment or it could become fatal.
